Re: AF to order A220, replace A380 with 787 or A350?

German media says 50-70 A220 order from AF on the way, to be placed by end of August at the latest. They also estimate same amount of A320/321 (NEO) will be ordered. https://www.aerotelegraph.com/bis-zu-70-airbus-a220-fuer-air-france Reuters: https://www.reuters.com/article/us-airbus-airfrance/airb...

1. The 787 can definitely take a larger fan.
2. You don't have to increase fan diameter to increase bypass ratio.

The "family concept" is overrated as an airline achieve massive scale. For large, network carriers, it is more important to have the right-sized aircraft with the right economics. A large fleet of A220s operated over decades, saves far more money than commonality does. This is why no carr...

In terms of passengers carried, definitely the 779 would be the best replacement. But, a 787-10 or A359 might be better in terms of yield (& profit).
