Looking for advice for seat choice on PS flight for next week. I'm already in C, seat 6C. Should I stay there or grab 9 A, B, or D. I chose 6C just in case a/c is downgraded to regular 757 so I would still have FC seat.

Also anyone have any idea how long taxi ride is to JFK from 54th and 6th ave in Manhattan at 5 am? (got a 7am flight JFK-SFO).

Thanks for the help!
