May 29, 2025, © Leeham News: We are writing an article series about stretching the A220 to a capacity in the A320neo range. The idea is to replace the A320neo over time to make room in the A320/321 production lines for more A321s and extend the A220 family with a larger variant.

We analyzed what we need to change to bring the capacity to the level of the A320neo. We could achieve this with a fuselage stretch, but then the Maximum TakeOff Weight (MTOW) would need to increase to keep the A220 range. The wing and engines would then have problems, the takeoff run would get longer, and the climb to an efficient initial cruise altitude would be affected.

We now examine the potential fixes for these problems.

Summary:

• The A220-300 wing is not highly loaded compared to other Airbus single-aisle aircraft. With some modifications, it should be sufficient for an A220-500.
• The A220 engine is the mid-sized Pratt & Whitney geared turbofan, the PW1500G. It has limited thrust stretch capability. An alternative for a long-range (and thus heavier) A220-500 would be the CFM LEAP-1B from the 737 MAX.
