Key Airport Options Near San Mateo
You’ve got a few airport choices near San Mateo when flying with pets. The main hub is San Francisco International Airport, which offers pet-friendly amenities and a good selection of airlines.
If you’re heading to or from Los Angeles, knowing your way around its airports will help you plan for your pet.
San Francisco International Airport
San Francisco International Airport (SFO) sits about 5 miles from San Mateo. It’s fairly pet-friendly, allowing service animals on the AirTrain and requiring other pets in terminals to be kenneled.
Most major airlines operate here, including Alaska, American, United, and Delta. Alaska Airlines, in particular, has a reputation for good pet policies.
You’ll find pet relief areas in the terminals, which is a relief (no pun intended) if your animal needs a break. SFO even has pet hotels nearby for longer stays.
The airport’s location and services make it a strong choice if you want less hassle traveling with your pet.
Accessing Los Angeles Airports
Los Angeles has several airports, but LAX is the big one. It’s about 340 miles south of San Mateo, so you’re looking at a long flight or a connection.
LAX offers pet relief areas and kenneling options, which is helpful. You might need a shuttle or a rental car to get to and from the terminals, depending on where you land.
If you fly into smaller airports like Burbank or Long Beach, expect less crowding but fewer pet-specific services. Planning your route ahead of time can make things smoother for you and your pet.
Regulations and Requirements for Flying with Pets
You’ll need to follow some rules when flying with your pet—think size, age, and health. There’s paperwork involved, and you should be ready for airport security checks.
Federal and State Government Regulations
Federal rules from the USDA and Department of Transportation set limits on how long an animal can be in a crate during travel. For example, flights over 12 hours usually can’t carry warm-blooded animals in cargo.
California state laws also protect animals during transport. Local rules might affect your trip, so check ahead.
Airlines often limit the types of pets allowed—mostly cats and dogs—and set size or breed restrictions.
Documentation and Health Certifications
You’ll need a current health certificate from your vet before flying. This proves your pet is healthy and fit for travel.
The certificate usually needs to be dated within 10 days of your flight.
Some destinations, especially international ones, might want extra paperwork—think vaccination records or quarantine clearance. Always check with your airline about what’s needed before you book.
Airport Security Preparation
At the airport, you’ll go through security with your pet. Smaller pets in the cabin usually have to stay in their carrier while you pass through screening.
Larger pets in cargo may need special handling, so ask your airline what to expect.
Make sure your pet’s carrier is labeled with your contact info. Keep some treats and water handy, but remember, all carriers must meet airline size limits and security rules.
Tips for a Smooth Pet Travel Experience
A little planning goes a long way to keep your pet safe and calm while traveling. Knowing how to pick animal transport services and keep your pet comfortable can really take the edge off.
Choosing the Right Animal Transport Services
When booking, always check the airline’s pet policies first. Some let small pets ride in the cabin, while bigger animals have to go in cargo.
If you’re bringing more than one pet, you might need to buy an extra seat.
Look for services that specialize in animal transport and have a solid reputation for safety. Ask if they’ve handled pets from San Mateo or your area before—it never hurts to double-check.
Gather all your documents early: health certificates, vaccination records, and anything else the airline wants. Every airline has its own list, so don’t leave this to the last minute.
Pet Comfort and Safety Guidelines
Use a sturdy, well-ventilated carrier that fits your pet just right. Your furry friend should be able to stand up, turn around, and stretch out inside.
Label the carrier with your contact info, just in case.
Let your pet spend some time in the carrier before the trip. Toss in a favorite toy, a treat, or maybe a blanket that smells like home.
Skip the big meal right before flying—nobody likes a queasy tummy, pets included.
Never sedate your pet unless a vet gives you the green light. Keep checking on them when you can, and do your best to keep things calm and quiet.
A familiar item or two can go a long way in making your pet feel safe. It’s not magic, but it definitely helps.
