Is Airbus taking for granted the Airbus-heavy fleet?
Still cannot fly LAX-SYD. Can't fly JFK-BOM.
Airlinepilotforums is probably the only place where you can read the 359 underperforms.
Here is an 8 page discussion between pilots from Cathay and Qantas validating A359, A35K performance and comparing it to 788, 789 and 777 as well. They use real flight data from several airlines (including published data from Delta) and Fcom .. No underperforming issues.
