I think Europe could work - like England , Ireland to PHL - then you could connect on our network all across the US. You could also connect on Wizz all over Europe. That article said Shannon airport was talking to F9 management. Also saw something about F9 talking to space ex about getting WiFi.

Hawaii could work also, but it is a more expensive destination. I know Allegiant tried it a while back when they had the 757s but it didn’t work out. Not sure why.
