Imagine a B767 based for example in STN or LTN or HHN or BGY. Bound to New York. Single ticket costs € 150 and return € 300.
Pax can go to the airport and buy the ticket or book a flight on a certain day but with no schedule provided. The 767 will depart when all seats are occupied with a maximum waiting time of 48 hrs.
Maybe, instead of JFK or EWR it can be a better choice PHL, relatively close to NYC.
I know something like this has already been tested some year ago, but I think times have changed and maybe it could work.
What do you think?
