Using the configuration data supplied by Airbus, the smaller A350-800 would compete directly with the 787; the larger A350-900 would go head-to-head with the 777-200.

However, Boeing's vice president of marketing, Randy Baseler, said Airbus is exaggerating its seating projections and that the larger A350 won't match up against the 777.

He claimed, instead, the plane's number of passengers would be comparable to that of the stretch version of the 787, the 787-9.
