That would likely be a bit claustrophobic should it ever be made. That's what I mean - big planes should be used between big hubs, for example leaving from the ocean beside England and landing in the ocean beside new york, then you take a bunch of trains to the various destinations.

Check-in, security checks and all that can then be distributed amongst all the small train stations. When you arrive at a plane hub, you just walk in with your hand luggage.

I used to think that smaller regional planes were the future, but nowadays I'm thinking perhaps the large titanicesque planes may be the way to go to solve this problem.
