Why Your Choice of Airline Matters When Flying with a Pet from New Orleans

Flying with a dog or cat out of Louis Armstrong New Orleans International Airport (MSY) demands more than just a carrier and a ticket. Every airline that serves the Crescent City has its own pet travel policies—and those policies can swing from exceptionally accommodating to near-impossible for some breeds or travel styles. The carriers that consistently rank as the best airlines for pets from New Orleans do more than say they accept animals. They publish clear fee structures, maintain climate-controlled cargo holds, and staff their gates with people who genuinely understand pet welfare. Picking the wrong one can mean surprise costs, a last-minute denial at the check-in desk, or a journey that risks your animal’s health.

New Orleans’ subtropical climate adds another layer of planning. Summer heat regularly triggers embargoes that block pets from traveling as checked baggage or cargo. Even during mild months, understanding which airlines allow in-cabin pets, what size carriers they accept, and how to prepare health documentation can make the difference between a calm trip and a frantic morning at the terminal. This guide gives you an expanded, airline-by-airline breakdown of pet travel rules from MSY, plus checklists that cover everything from carrier sizes to airport relief stops.

Pet Travel Options: Cabin, Checked, or Cargo

Before comparing individual airlines, it helps to know the three main ways pets are transported on commercial flights out of New Orleans:

  • In-cabin: Small pets ride under the seat in an airline‑approved carrier. This is the least stressful option for most animals. Weight limits (pet plus carrier) typically fall between 15 and 25 pounds.
  • Checked baggage: Larger pets travel in the cargo hold on the same plane as you. The compartment is pressurized and temperature‑controlled, but capacity can be limited. Airlines often charge more and may impose seasonal restrictions.
  • Cargo: For travelers who aren’t on the same flight or whose pets exceed checked‑baggage limits, dedicated cargo services move animals through freight terminals. This works for many large breeds and exotic animals but requires extra paperwork and advance booking.

Not every airline offers all three methods. Southwest, for example, only accepts in‑cabin pets. Knowing which service your airline provides is your first step.

Airline‑by‑Airline Guide: Top Carriers for Pets Departing New Orleans

American Airlines

American Airlines operates major routes from MSY and allows small cats and dogs in the cabin on most domestic flights. The combined weight of pet and carrier must stay under 20 pounds (9 kg). The carrier itself needs to be leak‑proof, ventilated, and small enough to slide under the seat in front of you. American’s soft‑sided carrier maximum is often around 18 x 11 x 11 inches, but exact dimensions appear on their website.

For larger dogs, American offers checked pet service via American Airlines Cargo. Expect higher fees and an earlier airport arrival—usually at least three hours before departure. A health certificate issued within 10 days of travel (30 days for some international destinations) is mandatory. Because New Orleans can be hot, American enforces seasonal heat restrictions; when ground temperatures exceed 85°F (29.4°C), checked pets may not be accepted. Always verify the latest heat embargo at American’s pet policy page.

In‑cabin pet fees typically range from $125 to $150 each way, while checked pet fees can be considerably higher. Booking early is essential—American caps the total number of pets per flight.

Delta Air Lines

Delta serves MSY extensively and permits small dogs, cats, and household birds in the cabin. The in‑cabin weight limit for pet plus carrier is often listed as roughly 20 pounds, though international flights may impose additional restrictions. Delta’s recommended soft‑sided kennel dimensions are 18 x 11 x 11 inches, and the carrier must fit completely under the seat.

For pets that are too large for the cabin, Delta Cargo moves animals as freight. This requires a separate booking through the Delta Cargo desk and a USDA‑approved shipping crate. During summer, Delta may refuse pets at cargo check‑in when temperatures rise above 85°F (29°C). A health certificate from a licensed veterinarian is required for all cargo and checked‑pet travel, and for many in‑cabin trips as well if you’re crossing state lines or international borders.

Delta’s pet fees can fluctuate, but cabin pets typically cost $95–$125 each way within the U.S. Visit Delta’s pet travel overview for the most current prices and paperwork checklists.

Southwest Airlines

Southwest’s pet policy is refreshingly simple: small, vaccinated domestic cats and dogs may travel in the cabin only. The carrier must be leak‑proof, well‑ventilated, and fit under the seat, with dimensions around 18.5 x 13.5 x 9.5 inches. The pet count per flight is capped at six, so booking early on your New Orleans departure can make or break your plans.

Southwest does not transport pets as checked baggage or cargo. If your dog or cat exceeds the in‑cabin weight limit (pet plus carrier roughly 20 pounds) or belongs to a brachycephalic breed that struggles with breathing, Southwest simply isn’t the right choice. The pet fee is a flat $95 per carrier each way, paid at booking or check‑in. Read Southwest’s full rules on their pets page.

Alaska Airlines

Alaska Airlines consistently earns praise from New Orleans pet owners for its well‑defined, animal‑friendly procedures. Small dogs, cats, rabbits, and household birds can fly in the cabin for a fee of $100 each way. The combined weight of pet and carrier must not exceed 20 pounds, and the carrier needs to fit under the seat—soft‑sided carriers up to 17 x 11 x 9.5 inches are typical.

For larger animals, Alaska offers both checked baggage service and dedicated cargo through Alaska Air Cargo. Temperature‑controlled holds keep animals comfortable, and Alaska’s staff is trained to handle pets with care. Still, summer heat embargoes apply, so plan morning or evening flights when temperatures are lower. Health certificates are required for all cargo and checked‑pet travel, and Alaska strongly recommends them even for in‑cabin journeys. Book your pet’s spot as soon as you purchase your ticket; flights fill up fast. The latest policy updates appear at Alaska Airlines’ pet travel page.

Frontier Airlines

Frontier operates several routes from New Orleans and allows small pets in the cabin on domestic flights. The pet‑plus‑carrier weight limit is approximately 22 pounds, making Frontier a slightly more generous option for a few extra pounds. Carriers must be soft‑sided, leak‑proof, and sized around 18 x 14 x 8 inches—check Frontier’s current dimensions before you pack. The one‑way pet fee is typically $99. Checked pets or cargo service are not available on Frontier, so larger animals cannot travel.

Since MSY can be sweltering, be mindful that Frontier may alter its pet policies during extreme weather. You can always find the most recent rules at Frontier’s pet info page.

United Airlines

United accepts in‑cabin pets on most domestic flights from New Orleans, with a fee of $125 each way. The pet and carrier together must stay under roughly 18–20 pounds, and carriers need to fit beneath the seat—typically around 18 x 12 x 11 inches for soft‑sided models. United also allows larger dogs and cats through its PetSafe program, a climate‑controlled cargo service that can be booked independently of your passenger ticket.

PetSafe requires a separate booking process and a special USDA‑approved crate. Because New Orleans’ summer weather often restricts cargo temperatures, it’s wise to call United’s PetSafe desk well in advance. A health certificate, proof of rabies vaccination, and careful crate sizing are mandatory. United’s complete pet travel parameters are listed on their travel with animals page.

Other Airlines: Spirit, JetBlue, and International Carriers

Spirit Airlines accepts small pets (dogs, cats, small household birds, and domestic rabbits) in the cabin for $125 each way. Weight limits hover around 20 pounds, and carriers must fit under the seat. No cargo or checked baggage option is available. Visit Spirit’s pet page for the latest.

JetBlue out of MSY permits in‑cabin pets with a $125 fee each way. The carrier must be no larger than 17 x 12.5 x 8.5 inches. JetBlue’s JetPaws program even includes a pet carrier tag, a list of pet‑friendly destinations, and bonus TrueBlue points. Larger pets cannot fly on JetBlue. Check JetBlue’s pet travel section.

For international flights, Air France sometimes allows pets up to 17–22 pounds in‑cabin, and larger animals in the hold. British Airways, Lufthansa, and other international carriers also serve New Orleans with specific rules. International health certificates, microchips, and import permits often apply, so start research months ahead.

In‑Cabin vs. Cargo: Making the Safest Choice for Your Pet

The in‑cabin experience keeps your pet close and minimizes anxiety, but it only works for small animals. When you book, confirm the exact weight limit—some airlines include the carrier weight, others don’t, and the total can be as low as 15 pounds. Pets with flatter faces (French Bulldogs, Persians) often struggle in the cabin’s pressure changes and should be carefully evaluated by a veterinarian before any air travel.

Cargo and checked‑baggage holds are pressurized and temperature‑controlled, but they’re noisier and require your pet to be alone for potentially long stretches. Airlines with stellar track records, such as Alaska and United’s PetSafe, manage these conditions well. However, heat restrictions from May through September around New Orleans can suspend these services with little notice. In those cases, driving to a cooler departure city or waiting for a winter flight may be your only alternatives.

Pet Carrier Guidelines and Size Requirements

An airline‑approved carrier is the single most important piece of gear you’ll buy. For in‑cabin travel, soft‑sided carriers with mesh ventilation panels are the norm. Look for these features:

  • Sturdy seams and zippers that can’t be nudged open from inside.
  • Leak‑proof bottom with an absorbent pad.
  • Secure straps that allow you to attach the carrier to a roller bag.
  • Dimensions that match your airline’s underseat space—commonly 17–19 inches long, 9–11 inches wide, and 9–11 inches high.

For cargo or checked baggage, a hard‑sided, USDA‑approved crate is mandatory. The crate must be large enough for your pet to stand without ears touching the top, turn around comfortably, and lie down in a natural position. Metal fasteners on all sides, a water bowl fixed to the door, and “live animal” stickers are standard. Always weigh your pet in the crate before you book; excess baggage weight can trigger additional fees.

Airline Pet Fees and Ticketing Procedures

Flying with a pet always adds to your travel budget. Here’s a rough snapshot of typical one‑way pet fees for flights departing New Orleans:

  • American Airlines: $125–$150 in‑cabin; higher for cargo.
  • Delta Air Lines: $95–$125 in‑cabin; cargo varies.
  • Southwest Airlines: $95 in‑cabin only.
  • Alaska Airlines: $100 in‑cabin; cargo fees quoted separately.
  • Frontier Airlines: $99 in‑cabin only.
  • United Airlines: $125 in‑cabin; PetSafe cargo varies.
  • Spirit Airlines: $125 in‑cabin only.
  • JetBlue: $125 in‑cabin only.

Fees are per carrier, so a single carrier with two small pets of the same species typically incurs just one charge—provided the combined weight stays under the limit. Always add your pet to your reservation either during online booking or by calling the airline directly. Waiting until the airport to declare your pet can lead to denied boarding if the flight’s pet capacity is already full.

Pet Relief Areas and Amenities

MSY offers designated pet relief stations both inside and immediately outside the terminals. These grassy, fenced patches give your pet a final chance to relieve itself before the flight. After the TSA checkpoint, post‑security relief areas exist in Concourses A and B. Look for signage indicating “Pet Relief Area” or check the airport map on the official MSY website. Airlines recommend a potty break no later than 90 minutes before your scheduled departure so you still have time to clear security and settle at the gate.

Health Documentation and Vaccinations

Nearly every airline asks for a health certificate from a licensed veterinarian, issued within 10 days of travel (sometimes within 30 days for international trips). The certificate confirms your pet is free of infectious diseases and fit to fly. Key items to have ready:

  • A current rabies vaccination certificate (pets under 3–4 months may be exempt, but age minimums apply).
  • Proof of other core vaccinations, particularly for kennels or international destinations.
  • A microchip registration document if required by the destination country.
  • Any import permits, parasite‑treatment records, or tapeworm certificates that your destination demands.

For domestic flights out of Louisiana, you seldom need more than the rabies certificate and health certificate. However, the State of Louisiana’s Department of Agriculture and national USDA guidelines can change, so double‑check with your veterinarian and the airline 30 days before departure.

Age and Breed Restrictions

Most U.S. airlines require pets to be at least 8 weeks old for domestic travel. International flights often push that age to 16 weeks or even 6 months. Brachycephalic (snub‑nosed) breeds—Bulldogs, Boxers, Persian cats—face extra scrutiny because of breathing difficulties. Some carriers ban these breeds from cargo holds entirely, even when they welcome them in the cabin. Confirm your pet’s breed status directly with the airline before paying for a ticket.

Heat Embargoes and Seasonal Considerations in New Orleans

New Orleans’ oppressive summer heat is the single biggest disruption for pet travelers. When ground temperatures climb above 85°F (29.4°C), many airlines stop accepting checked pets and cargo animals for the day. Even early‑morning and late‑evening flights can be affected, because the hold temperature can rise on the tarmac. The best defense is to book flights between November and March when temperatures are milder. If you must fly in summer, choose an airline that allows in‑cabin pets and schedule the earliest flight possible.

Booking Tips for a Smooth Pet Journey from MSY

  • Reserve your pet’s spot immediately. Pet capacity is limited to a set number per flight, often 2–6 animals in‑cabin. Don’t wait until the week before travel.
  • Call the airline directly. Many carriers don’t let you add a pet online for cargo or checked baggage. A phone agent can walk you through the paperwork.
  • Request a bulkhead seat. Some bulkhead rows don’t allow under‑seat storage, so ask specifically for a seat where a carrier will fit.
  • Pack a pet travel kit. Bring collapsible bowls, bottled water, a familiar blanket, and a small bag of treats. Don’t feed a large meal within four hours of departure to prevent nausea.
  • Label everything. Affix a tag with your name, cell phone, and destination address to both the carrier and your pet’s collar. Include a current photo of your pet in case of escape.

Weathering Delays and Cancellations with a Pet

MSY’s operations can be disrupted by thunderstorms and hurricanes, especially from June through November. If your flight is delayed, find a pet relief area immediately. During long holds, ask the gate agent if you can deplane with your pet for a bathroom break. Airlines generally won’t let you take the pet out of the carrier inside the terminal, so patience is key. Always have your veterinarian’s contact information handy in case your pet shows signs of stress.

International Pet Travel from New Orleans

Flying internationally with a pet from MSY adds layers of country‑specific rules. Besides the health certificate, you may need an endorsed USDA‑APHIS international health certificate, an import permit from the destination country, a microchip implantation (ISO‑compliant), and proof of taenia worm treatment. The process can take months, not weeks, so start by visiting the USDA’s pet travel site and your destination’s embassy pages. Many international airlines, including Air France and British Airways, serve New Orleans but enforce stricter weight limits and breed bans. Consult the airline’s cargo department directly before booking.

Final Checklist: The Day of the Flight from New Orleans

  • Print the pet health certificate and vaccination records; keep them in a waterproof pouch.
  • Attach a live‑animal tag and directional arrows to hard‑sided crates.
  • Arrive at MSY at least two hours early for in‑cabin pets, three hours for checked pets.
  • Skip the pre‑flight meal; offer small sips of water instead.
  • Walk your pet to the relief area immediately after parking.
  • At security, you’ll carry or leash your pet while the carrier goes through the X‑ray. Have a firm grip on the collar.
  • At the gate, keep the carrier closed and calm. A pheromone‑sprayed blanket can reduce anxiety.
  • Once boarded, slide the carrier fully under the seat and keep a hand on it during takeoff and landing.

Flying with a pet from New Orleans doesn’t have to be stressful when you choose an airline that treats animals as guests, not cargo. By matching your pet’s size and temperament to the right in‑cabin or cargo option, staying ahead of weather‑related restrictions, and nailing the paperwork, you can board your flight knowing you’ve done everything to keep your four‑legged companion safe and comfortable.
