The flight was awesome but a little long. I would prefer a flight with a layover. The amount of space available was minimal and a little uncomfortable for that long of a flight.

The flight was awesome but a little long. I would prefer a flight with a layover. The amount of space available was minimal and a little uncomfortable for that long of a flight.
