Currently have 2 PAX booked in IN on SFO-EWR, waitlisted for SFO-JFK.
SFO-JFK has XN available.
Am I better off:
1) Splitting the 2 PAX into their own reservations, so one of them has a better chance of clearing?
2) Booking the XN and doing a Plan B, without giving up the confirmed IN booking, and then cancelling one or the other closer in?
