When it comes to planning long-haul flights this summer, choosing the right cabin can make or break your trip. Economy class may get you there, but business class turns the experience into part of the vacation itself. From reclining seats and chef-curated menus to personalized service and elegant lounges, today’s best business class airlines have transformed flying into a luxurious art form.

For the summer of 2025, a few carriers outside the usual spotlight of Qatar and Singapore are impressing frequent flyers. Let’s take a look at some of these standout airlines that deserve your attention this year.

KLM Royal Dutch Airlines – Classic Style with Modern Comfort

Amsterdam-based KLM continues to impress with a product that balances European sophistication with passenger comfort. Their fleet of Boeing 787 “Dreamliner” aircraft offers fully flat seats with direct aisle access, large windows, and improved cabin air pressure for less flight delay.

What makes KLM one of the best business class airlines in 2025 is its simple charm. The catering service offers Dutch-inspired dishes, and every passenger receives a collectible miniature Delft Blue house filled with Dutch gin—an iconic amenity that loyal customers adore. For travelers heading to Europe this summer, KLM is offering competitive prices and convenient connections via Amsterdam Schiphol.

SWISS International Air Lines—Simple European Luxury

Zurich-based SWISS has long been associated with efficiency and precision, and their long-haul business class reflects just that. The staggered seating arrangement gives many passengers extra privacy, especially the sought-after “throne seats.”

Another highlight: SWISS collaborates with regional chefs across Switzerland to create menus that highlight seasonal Alpine ingredients. This attention to culinary excellence places them firmly among the best business class airlines  for travelers who appreciate good food in the air.

Delta Air Lines—Delta One Suites

Delta has redefined premium travel in the US with Delta One Suites. Featuring sliding doors, direct aisle access, and premium bedding by Westin, these suites provide a private and relaxing space even on busy transatlantic routes.

In 2025, Delta continues to roll out its Airbus A350 and 767 cabins, ensuring that more passengers can enjoy this experience. Combined with Sky Clubs and strong operational reliability, Delta is now recognized as one of the best business-class airlines flying from the US.

United Polaris—Consistency Across the Network

United’s Polaris Business Class has been continuously improved since its debut, and by the summer of 2025, the experience will finally be consistent across nearly all of its long-haul aircraft. Every seat converts to a fully flat bed with direct aisle access, and the plush product—the Saks Fifth Avenue bed, enhanced food service, and dedicated Polaris lounges in key hubs—adds to the appeal.

For U.S. travelers heading to Europe or Asia, United’s extensive route network coupled with the Polaris product makes it one of the best business class airlines for global coverage.

American Airlines Flagship Business—Improved and Competitive

American Airlines has invested heavily in its premium long-haul cabins. Flagship Business seats on the revamped 777-300ER and 787 Dreamliner offer spacious seats, ample storage, and comfortable bedding. On select routes, American Airlines also offers Flagship Dining, an exclusive pre-flight experience that feels more like a fine dining restaurant than an airport lounge.

These improvements have helped American Airlines secure a stronger reputation among airlines, especially for transatlantic routes to London, Paris, and Madrid.

Finnair—Scandinavian Simplicity with Innovation

Finnair took a bold step in redesigning its long-haul business class with seats that don’t recline in the traditional sense. Instead, they use a fixed, soft-padded shell that transforms into a wide, flat sleeping surface. This innovation, coupled with the soothing aesthetic of Nordic design, sets Finnair apart.
Flying via Helsinki will also mean seamless connections between Europe and Asia, making Finnair one of the most exciting and innovative options among the best business class airlines in 2025.

Iberia—Spanish Style and Comfort

Often overlooked, Iberia has quietly built a competitive business class offering. Their Airbus A350 aircraft feature modern reclining seats, large entertainment screens, and Spanish wines and tapas-style food. For travelers heading to South America, Iberia offers one of the best networks with direct flights from Madrid. For those looking to combine affordability with style, Iberia is an underrated member of the best business class airlines club this summer.

Qantas Airways—The Kangaroo Route Expert

For decades, Qantas has perfected long-haul travel between Australia and the rest of the world. Its business class on Boeing 787-9s and Airbus A380s features spacious seats, a fine selection of Australian wines, and the comfort of dishes designed by celebrity chef Neil Perry.
What makes Qantas among the best business class airlines in 2025 is its emphasis on well-being. From in-flight stretching exercises to lighter, fresher meal options, Qantas understands the unique demands of ultra-long-haul flights like Sydney-London.

Korean Air—Blending Tradition with Modernity

Korean Air’s Prestige Suites on Boeing 787s and 777s combine modern design with classic Korean hospitality. Expect warm service, delicious Korean meals like bibimbap, and high-quality amenities.
The airline also benefits from an efficient Seoul Incheon hub, which offers one of the smoothest transfer experiences in Asia. These details place Korean Air firmly in the ranks of the best business class airlines for travelers heading across the Pacific.

Oman Air—Boutique Luxury in the Middle East

While not as big as Emirates or Qatar, Oman Air offers a boutique experience that rivals both. Business Class seats on its A330 and 787 aircraft are spacious, with a 1-2-1 configuration that gives every passenger direct aisle access. Omani-inspired hospitality and fine dining menus add cultural richness to the journey. For those flying between Europe, Asia, and the Middle East, Oman Air remains one of the hidden gems among the best business class airlines in 2025.
