Introduction: Sun Country Airlines in 2025

Sun Country Airlines has solidified its role as a focused, affordable carrier for leisure travelers departing the Upper Midwest and an increasing number of point-to-point vacation markets. Headquartered in Minneapolis, the airline operates a growing network that spans the continental United States, Mexico, the Caribbean, and Central America. What started as a small charter operation in 1983 has evolved into a publicly traded ultra-low-cost carrier (ULCC) with a fiercely loyal following among travelers who understand its à la carte philosophy. In 2025, Sun Country competes directly with Spirit, Frontier, and Allegiant on price while differentiating itself through an all-Boeing 737 fleet, friendly service, and a route map that prioritizes sun, snow, and outdoor destinations.

For passengers, getting the most from Sun Country means embracing the unbundled model. A low base fare is just the entry point—luggage, seat assignments, and even carry-ons must be purchased separately. This detailed guide unpacks every fee, policy, and perk so you can plan a trip that stays within your budget. You’ll find updated baggage rules, seat selection costs, change and cancellation policies, loyalty program insights, and a look at how the carrier stacks up against its ULCC rivals. By the end, you’ll know exactly how to keep the total ticket price low without sacrificing comfort.

History and Fleet Evolution

Sun Country’s story is one of adaptation. The airline launched as a charter outfit for tour operators, carrying vacationers to warm-weather spots and casino junkets. Ownership changed hands multiple times, including a period under the umbrella of a Minnesota-based business group and a brief bankruptcy filing that led to a restructuring in 2008. The pivot to a low-cost scheduled model came in the 2010s, and a public listing followed. Since then, Sun Country has focused relentlessly on cost control and fleet simplicity.

By early 2023, the airline completed an important milestone: retiring its last Boeing 737-700 in favor of a uniform fleet of 737-800s and 737 MAX 8 aircraft. The 2025 fleet comprises roughly 50 aircraft, with the MAX 8 continuing to arrive under an existing order book. The 737-800s are configured with 186 seats in a single economy cabin, while the newer MAX 8s seat 189. These slimline seats average 30 inches of pitch in standard rows, though exit rows and forward-positioned Preferred seats can stretch to 34 inches. A uniform fleet slashes maintenance, crew training, and parts inventory costs—savings that help fuel the airline’s famously low entry-level fares.

Route Network and Destinations in 2025

Sun Country’s network follows a hybrid strategy: scheduled year-round flights from Minneapolis-St. Paul (MSP) to key cities, plus a robust seasonal portfolio that ebbs and flows with vacation demand. Winter brings near-daily frequencies to Cancún, Puerto Vallarta, Punta Cana, Montego Bay, and Liberia (Costa Rica). Summer unleashes service to Anchorage, Portland (Maine), Traverse City, and other outdoor-oriented markets. Year-round, the airline connects MSP to Dallas-Fort Worth, Denver, Las Vegas, Orlando, and Phoenix, among others.

What sets the 2025 route map apart is the expansion into smaller secondary airports. New routes from Provo, Utah; Melbourne, Florida; and St. Cloud, Minnesota cater to communities that legacy carriers typically serve only with regional jets or not at all. A crucial ingredient is the airline’s partnership with tour operators and package-vacation sellers. These bulk purchases stabilize demand and allow Sun Country to fly thin routes profitably. The carrier does not serve massive corporate hubs like New York, Chicago O’Hare, or Washington, D.C., and has no intention to do so—its identity is thoroughly leisure-driven.

Baggage Policy: Fees, Dimensions, and Strategies

The Free Personal Item

Every fare includes one personal item that must fit beneath the seat ahead. Dimensions are limited to 17 x 13 x 9 inches (43 x 33 x 22 cm). A purse, small backpack, laptop bag, or diaper bag all qualify. If your item cannot be squeezed into the sizer at the gate, you’ll pay a gate-check fee that is substantially higher than an online carry-on purchase—sometimes north of $60 per segment. Travelers who pack light and stick strictly to a compliant personal item avoid all baggage charges, which is the ultimate ULCC money-saving move.

Carry-On Baggage

Overhead bin space is not complimentary. A full-sized carry-on (maximum 24 x 16 x 11 inches, including wheels and handles) must be purchased. There is no published weight restriction, but you need to be able to lift it solo. When you prepay online during booking or via the “Manage Travel” section on the Sun Country website, the carry-on fee typically ranges from $30 to $45 per segment. Pricing is dynamic—popular dates and routes climb toward the upper end. At the airport, the carry-on charge commonly jumps to $50 or more. Locking in your decision during the original booking is the cheapest path.

Checked Baggage

Checked bags are also an add-on. Sun Country accepts up to two checked pieces per passenger, each adhering to a linear size limit of 62 inches (length + width + height) and a weight cap of 50 pounds (23 kg). Prepaid online, the first bag runs $30–$45, and the second $40–$55. Airport counter rates start around $50 and $60 respectively. Overweight luggage—between 51 and 70 pounds—incurs an additional fee that can reach $100, while oversized pieces over 62 linear inches also trigger a $100+ charge. Bags heavier than 70 pounds are not accepted.

Special items like golf clubs, skis, and snowboards are treated as standard checked bags as long as they fit within size and weight limits. A rigid ski case that exceeds 62 linear inches will face the oversize surcharge. Instruments that fit within carry-on dimensions may travel in the cabin if you buy a carry-on allowance; larger instruments must be checked and face the same oversize and overweight rules. Always consult the official Sun Country baggage page for the latest numbers.

Seat Selection and Boarding Options

Sun Country does not assign a specific seat with the base fare. Instead, you can choose to pay for a seat or let the airline randomly assign you one, free of charge, at check-in. Seats fall into three pricing tiers:

  • Standard seats: $10–$30 per segment. These are the majority of the cabin and represent the most affordable way to secure a specific spot.
  • Exit row seats: $20–$50 per segment. With 34 inches of pitch, these provide meaningful legroom, especially on flights longer than three hours.
  • Up-front Preferred seats: Positioned in the first several rows, these cost the most but offer quicker deplaning and, in some cases, a bit more recline.

Priority boarding can be tacked on for a fee and is especially useful for anyone who has paid for overhead bin space. Priority boarding passengers board after pre-boarding but ahead of general groups, reducing the odds that the bins will fill up and force a gate-check of your carry-on.

Change, Cancellation, and Refund Policies

Sun Country’s change-fee structure is relatively straightforward and compares favorably with the basic economy offerings of legacy carriers. The fee depends solely on how far in advance you act:

  • 60 days or more before departure: No change fee. You pay only any fare difference.
  • 14 to 59 days before departure: A $39 change fee per passenger, plus fare difference.
  • 0 to 13 days before departure: A $99 fee per passenger, plus fare difference.

Cancellations do not produce cash refunds. Instead, you receive a travel credit valid for one year from the original booking date. This credit is not transferable and can only be applied to future Sun Country flights. For extra peace of mind, the “Flight Flex” add-on (purchased at booking) reduces or eliminates change fees and adds other flexibility perks. For most travelers, the standard policy is manageable, but if your plans are tentative, Flight Flex is worth pricing out.

In-Flight Experience: Food, Drinks, and Entertainment

As a ULCC, Sun Country offers a buy-on-board refreshment service. Complimentary snacks and soft drinks are not part of the deal, but the for-purchase menu includes snack boxes, sandwiches, and an array of alcoholic and non-alcoholic beverages. Prices are typical for a U.S. low-cost carrier—think $3–$4 for a soft drink or coffee, $7–$9 for a beer or wine, and $8–$12 for a meal kit. You can also bring your own food and non-alcoholic drinks through security, which many budget-conscious travelers do.

In terms of seat comfort, Sun Country’s slimline seats are more cushioned than those found on some competitors, and the 30-inch pitch is slightly better than Spirit’s 28-inch standard. Power outlets and USB ports are available on most MAX 8s, and the airline has rolled out a streaming in-flight entertainment system available through your own device. No seatback screens are installed. Overall, the cabin experience prioritizes low costs, but the friendliness of the Minneapolis-based flight crews regularly earns positive mentions in reviews.

Sun Country Rewards Program

Sun Country Rewards is a spend-based loyalty program, not a distance-flown scheme. Members earn points on every dollar spent on Sun Country flights, including taxes and ancillaries like bags and seat fees. Redemption options include flights, vacation packages, seat upgrades, and merchandise. The program is refreshingly simple—there are no complex award charts or blackout dates for flight redemptions, which makes it particularly appealing to leisure travelers who fly a few times a year.

Three elite tiers unlock progressively valuable perks: complimentary checked bags, priority boarding, dedicated check-in lines, and expedited customer service. Status is earned through qualifying spend and segments. The top tier mirrors some benefits of legacy airline mid-tier status, minus lounge access or upgrade instruments. For those who fly Sun Country regularly to Mexico or the Caribbean, the program can deliver genuine value, especially when paired with the airline’s co-branded credit card—though card availability and terms change, so checking directly with the airline is wise.

Customer Satisfaction and Operational Performance

Online reviews for Sun Country paint a picture of a carrier that does the basics well but isn’t immune to the ULCC fee-related frustrations. The airline earns praise for its low upfront fares, efficient boarding, and friendly cabin crew, according to reviews on Skytrax. Complaints often center on the accumulation of fees, the absence of complimentary in-flight snacks, and limited phone support (Sun Country does not operate a 24/7 call center).

Operational statistics help tell the story. In 2024, the U.S. Department of Transportation’s Air Travel Consumer Report showed Sun Country with a mishandled baggage rate and involuntary denied boarding rate below the industry average. On-time performance hovers near 80%, aided by the airline’s concentration of flights at MSP and its avoidance of the most congested northeastern corridors. These numbers reveal a carrier that executes a relatively simple operation with discipline.

Pros at a glance:

  • Ultra-low base fares on leisure routes
  • Modern, all-Boeing fleet with new MAX 8 deliveries
  • Unbundled pricing lets you pay only for what you use
  • Crew friendliness and cabin comfort often rank above ULCC peers

Cons to consider:

  • Baggage fees can quickly lift the total cost above a legacy carrier
  • Limited route network focused on vacation spots, not business hubs
  • No free carry-on—overhead bin space always costs extra
  • No 24/7 customer service and no traditional refunds

How Sun Country Compares to Other ULCCs

Travelers frequently weigh Sun Country against Spirit, Frontier, and Allegiant. Direct fare comparisons are tricky because each airline bundles and unbundles differently. However, a few patterns hold. Sun Country’s standard seat pitch of 30 inches is consistent with Frontier and slightly more generous than Spirit’s 28 inches. Seat cushion comfort is subjectively better, and the carrier’s online bag fees are often a few dollars cheaper than Spirit’s early-purchase rates. The real differentiator is network focus: while Spirit and Frontier chase volume on major business routes, Sun Country doubles down on leisure-heavy, point-to-point service from the Upper Midwest and secondary markets.

Allegiant shares a similar leisure-first ethos, but Sun Country’s all-Boeing 737 operation and slightly broader international reach set it apart. Another advantage is Sun Country’s charter business. The airline operates flights for college sports teams, casinos, and tour operators, which provides reliable revenue during off-peak travel periods. This financial cushion has allowed Sun Country to avoid some of the dramatic capacity fluctuations that have buffeted other ULCCs.

Booking Tips and Money-Saving Strategies

Maximizing value on Sun Country requires a bit of planning. Use these tactics to keep your total trip cost as low as possible:

  • Book bags at the time of ticket purchase. Prepaying for a checked bag or carry-on during the initial booking locks in the lowest price. Bag fees rise as departure nears, so indecision is expensive.
  • Master the personal-item-only approach. A well-packed 17 x 13 x 9-inch backpack can hold a surprising amount. On a short weekend trip, you can eliminate all luggage fees and breeze through boarding.
  • Weigh and measure bags at home. A portable luggage scale costs less than a single overweight fee. Confirm dimensions and weight before leaving the house to avoid counter surprises.
  • Check alternative airports. Sun Country flies to many smaller airports. If you live near one, you might find a nonstop vacation flight that would otherwise require a connection on a larger carrier.
  • Use the Sun Country mobile app. It stores your boarding pass, delivers real-time gate updates, and lets you manage bags and seats up until check-in. Having it saves time and helps you react if your flight changes.
  • Consider Flight Flex only if plans are shaky. For most trips, the standard change-fee schedule is acceptable. But if your dates are uncertain, Flight Flex can save money compared to paying multiple change penalties.

Looking Ahead: What’s Next for Sun Country

The 2025 outlook for Sun Country points to controlled growth. The airline will take more 737 MAX 8 aircraft, which offer 20% better fuel efficiency per seat than the 737-800 and a noticeably quieter cabin. New seasonal routes to secondary airports in the Caribbean and Mountain West are likely, and there’s persistent industry chatter about a premium seating product. Whether a “Big Front Seat” with extra width and pitch or a blocked-middle-seat option, such a move would mirror what Spirit has done and unlock additional revenue without sacrificing the low-cost base model.

Regulatory changes could also influence the landscape. The DOT’s push for clearer fee disclosure and stronger passenger compensation rules might nudge Sun Country toward even more transparency in its booking path. For passengers, the ability to compare all fees upfront—already a strength of Sun Country’s website—makes it easier to evaluate whether that $49 fare really beats a legacy carrier ticket. Tools like the metasearch site Aviasales can help shoppers stack up all airlines on a given route in one view.

Final Thoughts

Sun Country Airlines isn’t trying to be a full-service global carrier, and that’s its greatest strength. It delivers rock-bottom lead-in prices to beaches, national parks, and family hotspots, then charges individually for the extras that leisure travelers actually care about. By understanding the bag policies, seat fees, and change rules, and by booking add-ons early, you can build an affordable, comfortable trip without the sticker shock that sometimes accompanies ULCCs. For anyone flying from the Upper Midwest or seeking a no-frills connection to the sun, Sun Country remains one of the most practical and dependable options in the sky.
