*aerospace · news · 2026-04-30 · Simple Flying*

## Key points

- The A220-300 has about a 12% per-seat cost advantage over the A319neo and 737 MAX 7.
- Nearly a fifth of the global A220 fleet is grounded due to Pratt & Whitney PW1500G engine issues.
- SWISS and Egyptair have grounded major portions of their A220 fleets due to engine reliability concerns.
- A220 sales are currently hampered by engine maintenance delays and higher-than-expected maintenance costs.
- The 737 MAX 7 retains much of the MAX 8's structure, making it heavier and less efficient than A220.
