10. Frontier Airlines: Flying Green

Frontier Airlines has redefined low-cost travel by committing to sustainability like no other airline. As North America’s greenest airline, Frontier prioritizes reducing its environmental footprint through initiatives like lightweight seats, fuel-efficient engines, and biodegradable cups. Their planes’ iconic animal-themed tails—from Francie the piping plover to Hudson the bog turtle—highlight the airline’s commitment to conservation.

This Denver-based carrier also continues to expand its reach. In 2024, Frontier significantly increased its routes from Phoenix Sky Harbor, making budget-friendly, eco-conscious travel accessible to more passengers. Travelers on a budget can feel good knowing they’re flying with an airline that’s as invested in the planet as it is in providing affordable options.

In 2025, Frontier Airlines news highlights an exciting network expansion with 16 new routes across 21 airports in the United States and the Caribbean. These routes include a return to Tucson, Arizona; Reno, Nevada; and Antigua and Barbuda, with fares starting as low as $19. These additions reflect Frontier’s commitment to providing affordable travel options and connecting passengers to a broader range of destinations.

9. Allegiant Air: Affordable and Accessible

Allegiant Air knows its niche: connecting smaller cities to major destinations with affordable, no-frills flights. For travelers looking to avoid crowded hubs, Allegiant is a standout option. Think routes like Savannah to Akron-Canton or Grand Rapids to Sarasota—perfect for skipping long drives or inconvenient layovers.

Though its offerings are stripped-down (pack your snacks!), the airline’s consistently low fares make it a top choice for cost-conscious flyers. One reader even described it as “the best airline for regional airports,” praising its ability to bring convenience to places often overlooked by larger carriers. Allegiant proves that regional travel doesn’t have to come at a premium.

8. American Airlines: Global Connections

As the largest airline in the world by fleet size, American Airlines excels in connecting passengers across the globe. Its 10 domestic hubs, including Miami and Dallas/Fort Worth, serve as gateways to an extensive network spanning the Caribbean, Latin America, and beyond.

In 2024, American Airlines introduced new routes to lesser-known destinations like San Andres Island, Colombia, and Chetumal, Mexico—adding variety for adventurous travelers. The airline has also made strides in innovation, committing to supersonic jets from Boom to shorten transatlantic flight times in the future. With its combination of reliability, global reach, and forward-thinking technology, American remains a powerhouse in the industry.

One of the best airlines to fly to Europe from the USA, American Airlines, will fly to five new routes to Europe for the summer of 2025.

7. United Airlines: Endless Horizons

United Airlines continues to stand out with its ambitious expansion into international markets. In 2024, the airline introduced flights to destinations like Amman, Bergen, Mallorca, and Lagos, adding to its already impressive global footprint. United’s hubs, spread across the U.S. from Chicago to Guam, make it a versatile choice for both domestic and international travel.

Passengers also appreciate United’s commitment to sustainability. With 270 new fuel-efficient aircraft set to join its fleet, the airline is working to reduce emissions while enhancing passenger comfort. Add in its decision to eliminate most change fees, and United Airlines is a strong contender for travelers looking for flexibility and a broad range of options.

United Airlines has announced its largest international expansion in history. Starting in May 2025, it will launch new services to eight cities.

6. Southwest Airlines: Bags Fly Free

Southwest Airlines has long been a favorite among budget-conscious travelers, and 2024 was no exception. Known for its “bags fly free” policy, which allows passengers to check two bags at no cost, Southwest continues to offer unbeatable value.

Its expansive route network now spans Hawaii, Latin America, and the Caribbean, proving that “Southwest” is no longer just a regional name. While the open seating policy remains a polarizing feature, travelers agree that Southwest’s friendly service and dependable schedules make it a top pick. For those who value simplicity, transparency, and great deals, Southwest delivers every time.

Southwest’s summer 2025 schedule now includes 33 overnight flights with service from Hawaii and the West Coast, traveling east to various key Southwest cities.

5. Hawaiian Airlines: Island Vibes in the Sky

Hawaiian Airlines offers more than just a flight—it provides a preview of island life. From the moment you board, you’re treated to a uniquely Hawaiian experience, complete with island-inspired snacks like caramel macadamia nut popcorn and furikake chips.

The airline also shines in premium service, offering lie-flat seats on ultra-long-haul routes and exclusive cocktails in partnership with On the Rocks. Hawaiian’s reliability is another standout feature, with the airline consistently ranked as one of the most punctual in the country. Whether you’re traveling inter-island or heading to the Pacific Rim, Hawaiian Airlines makes the journey as enjoyable as the destination.

In a significant development in 2024, the U.S. Department of Justice has allowed the proposed $2 billion merger between Alaska Airlines and Hawaiian Airlines to advance, marking a pivotal moment in the U.S. airline industry. This merger aims to broaden travel options from Hawaii to the mainland United States and expand Alaska Airlines’ international presence. The DOJ’s decision not to block the merger indicates a green light for the airlines to proceed, though final approval from the U.S. Department of Transportation is still pending.

4. Tradewind Aviation: Boutique Excellence

For travelers seeking exclusivity and personalized service, Tradewind Aviation is a hidden gem. Specializing in private charters and shuttle flights, Tradewind provides unparalleled convenience to high-end destinations like Nantucket and St. Barts.

Flying with Tradewind means skipping crowded terminals and enjoying private lounges stocked with refreshments and snacks. With a fleet of propeller planes and Citation jets, this boutique airline offers a stress-free, luxury experience that’s hard to match. For those who value time, comfort, and privacy, Tradewind is the ultimate way to travel.

3. Alaska Airlines: Tech-Savvy and Traveler-Friendly

Alaska Airlines has won over passengers with its friendly service and thoughtful details, like craft beer and wine from the Pacific Northwest. Though once considered a regional carrier, Alaska now boasts a network spanning from Hawaii to Mexico and the East Coast.

The airline is also a leader in sustainability, partnering with Twelve to develop aviation fuel made from recaptured carbon dioxide. Alaska’s commitment to innovation, paired with its generous rewards program, keeps it among America’s favorite airlines. Whether you’re flying for work or pleasure, Alaska delivers a seamless and enjoyable experience.

2. JetBlue Airways: High-Flying Comfort

JetBlue continues to redefine the flying experience with its passenger-first approach. Features like free high-speed Wi-Fi, extra legroom, and seat-back entertainment set it apart from competitors. The airline’s Mint Class, with spacious lie-flat seats, is a favorite for transatlantic routes, including flights to London.

JetBlue also earns praise for its consistent innovation. In 2024, it expanded its offerings to include more flights out of Boston, solidifying its status as a major player in the U.S. market. JetBlue is set to enhance its premium offerings by introducing its first-ever airport lounges at New York’s JFK International Airport and Boston Logan International Airport. The JFK lounge, spanning 8,000 square feet, is scheduled to open in late 2025, followed shortly thereafter by an 11,000-square-foot lounge at Boston Logan.

These lounges will feature areas designed for relaxation, work, and socializing, complemented by JetBlue’s distinctive branding and local artwork. This initiative reflects JetBlue’s commitment to elevating the travel experience for its premium customers.

1. Delta Air Lines: A First-Class Experience

Delta Air Lines remains the gold standard in American aviation, thanks to its blend of luxury, innovation, and reliability. The airline’s stunning $4 billion terminal at New York’s LaGuardia Airport, featuring art installations, high ceilings, and premium lounges, set a new benchmark for airport design.

Onboard, passengers rave about Delta’s free in-flight messaging, cozy business class suites, and premium dining options.
