Boeing 757-200 vs Airbus A321neo

The Boeing 757-200 and Airbus A321neo are compared because the Airbus is the first single-aisle able to do most of what the 757 did. The 757-200, in service from 1983 and out of production since 2004, is a 47.3 m narrowbody seating around 200 in two classes, with Rolls-Royce RB211 or Pratt & Whitney PW2000 engines of up to 43,000 lb thrust and a range of about 3,900 nautical miles. Its power gave it superb hot-and-high and short-runway performance and, in the 2000s, made it the aircraft that opened transatlantic routes from secondary US cities. The A321neo, in service since 2017, is 44.5 m long, seats around 206 in two classes, and in its long-range version flies about 4,000 nautical miles; the A321XLR extends that to 4,700.

The A321neo burns 20 to 25% less fuel than a 757-200 on the same route, which is why Delta, United, American, JetBlue, Icelandair and Aer Lingus are replacing their 757s with it. What it cannot match is the 757's raw thrust and climb performance, which matters at high-altitude airports and on the longest sectors, and its payload at range. The XLR, with an extra permanent fuel tank, is Airbus's explicit answer to the 757's transatlantic role, and it entered service in 2024.

Passenger experience

Both are long 3-3 cabins. The A321neo's fuselage is about seven inches wider than the 757's, so its seats are typically 18 inches against 17, and its Airspace cabin has larger bins and a quieter interior. The 757 is older and louder, though Delta's and United's remaining aircraft have been refurbished with modern seats and lie-flat business class on transatlantic routes, and the 757's tall landing gear gives it a distinctive high ride. Transatlantic A321neos at JetBlue, Aer Lingus and TAP carry lie-flat business seats as well. Both are slow to board through forward doors; sit near a door if you have a connection. For the best seat on either, take a window forward of the wing or an exit row.

Which to choose

For airlines the A321neo is the obvious economic choice, and the 757 survives only where its performance is irreplaceable or its purchase price long since written off. For passengers the A321neo is the wider, quieter and newer aircraft; the 757 is the one with the history.
