Cargo considerations
I always understood that one reason for the A300 JFK-SDQ was the greater cargo capacity. So either a reduced cargo business or fleet consolidation considerations (or both) are conspiring against the A300 and other twin aisles.
If you fly AA, you may learn to miss the A300 when you're packed like a sardine into seat 39B on a 757 and it takes half an hour to deplane down the single aisle.
