I'd like to see the results of loading several hundred people into a widebody jet in a free-for-all for seat assignment with a 30 minute turnaround :-) (from a safe vantage point, of course...)
Yeah, and after 6 hours with their knees in their faces, eating 10 euro plastic sarnies, arriving into 'New York East' (Windsor Locks) and 'Boston North' (Bangor Maine) - with fleets of busses to take them to Kennedy and Logan for their onward journies of course.
I doubt those hour long taxi delays and International Landing Charges in KJFK would suit MOL?
