The combined fleet is incredibly diverse, ranging from ultra-long-haul widebodies to regional turboprops.
The backbone of the alliance's domestic and regional networks is dominated by two families:
For transcontinental flights, the alliance features some of the most advanced jets in the sky:
NG • Shortest 737
Introduced in 1998 as the smallest Next-Generation 737, the -600 was the direct replacement for the classic 737-500. With room for about 130 passengers, it found a niche on regional and short-haul routes where capacity mattered less than efficiency. Scandinavian Airlines was one of the largest operators—ideal for thin Nordic and European sectors.

NG • Medium Range
The 737-700 entered service in 1998 and effectively replaced the 737-300. It became a favorite for domestic and thin international routes, with a 6,230 km range that allowed transcontinental US flights. The -700ER variant, launched in 2006, offered extended range for operators like All Nippon Airways, pushing the narrowbody into long-haul markets.

NG • High-Capacity Workhorse
Launched in 1998, the 737-800 quickly became the best-selling 737 NG variant and the backbone of low-cost and traditional carriers alike. With 162–189 seats and 5,765 km range, it defined medium-haul narrowbody operations for two decades. Thousands were built, and it remains one of the most common jetliners in the sky today.

The 737-900 entered service in 2001 as the longest 737 NG, stretching the fuselage to seat up to 189 passengers. It targeted high-density domestic and medium-haul routes. The -900ER (Extended Range) followed in 2007 with extra fuel and optional exits, making the platform even more flexible for airlines like United and Lion Air.

MAX • LEAP Power
Boeing’s answer to the A320neo, the 737 MAX 8 first flew in 2016 and entered service in 2017. It combines the LEAP-1B engine and advanced winglets with a familiar fuselage, cutting fuel burn by double digits versus the 737-800. The type faced a worldwide grounding in 2019–2020 after two accidents; it returned to service with updated software and procedures and now flies for carriers globally.

It fills the gap between the MAX 8 and the MAX 10 and is popular with airlines that need extra capacity on busy medium-haul routes without stepping up to a widebody.

The 737 MAX 10 is the longest 737 ever built and began deliveries in 2023. It seats up to 230 in a single-aisle layout and competes directly with the Airbus A321neo for high-density domestic and medium-haul routes. Unique folding wingtips allow it to use the same gate footprint as smaller MAX variants while maximizing wingspan for efficiency.

CEO • Smallest A320
The A318 entered service in 2003 as the smallest member of the A320 family—often called the “baby bus.” With 107–132 seats and 5,950 km range, it was aimed at regional and thin routes. A standout feature: it was certified for steep approaches into London City Airport. Only about 80 were built, making it a rare and distinctive narrowbody.

The A319 entered service in 1996 as the shortened version of the A320, seating 124–156 passengers with up to 6,850 km range. It became a workhorse for domestic and medium-haul networks and is also widely used as a corporate or government jet. Several air forces operate it in tanker or transport roles, and it remains in production today as part of the A320ceo family.

The A320-200 entered service in 1988 and helped redefine single-aisle travel with fly-by-wire controls and a wider cabin than the 737. It became the core of the world’s best-selling narrowbody family and sparked the rivalry with Boeing that still defines the market. Thousands of -200s remain in service alongside the newer A320neo.

It proved that a narrowbody could handle dense domestic and medium-haul routes without a second aisle. The type laid the groundwork for today’s A321neo, LR, and XLR variants that dominate medium-haul growth.

It quickly became the default choice for airlines renewing their single-aisle fleets and has outsold the 737 MAX in orders, defining the current generation of narrowbody travel.

Airlines use it to replace older A321ceos and 757s on busy medium-haul routes. It also forms the base for the long-range LR and extra-long-range XLR, making the A321neo family the most versatile narrowbody in production.

Powered by Pratt & Whitney’s GTF, it opened a new market: long-haul point-to-point with a single-aisle. Airlines use it to serve secondary city pairs that don’t justify a widebody.

The A321neo XLR entered service in 2023 with a record 8,700 km range—the longest of any single-aisle airliner. It effectively brings “mini widebody” range to a narrowbody, enabling nonstop transatlantic and other long thin routes with lower trip cost than a twin-aisle. The XLR is a key part of airlines’ strategies for point-to-point long-haul.

The A330-200 entered service in 1998 as the shorter, longer-range sibling of the A330-300. With 13,450 km range and 246–406 seats, it was designed for ultra long-haul and thin long-haul routes where the -300 was too big. It became a favorite for airlines like Emirates, Qantas, and many others on marathon sectors such as Dubai–Sydney or London–Perth.

More than 1,500 -300s have been built; it remains a classic workhorse for full-service and leisure carriers, with 277–440 seats and 11,750 km range.

With 287–440 seats and 13,334 km range, it is the modern replacement for the classic -300 and a key widebody for medium- and long-haul networks.
