I would specifically contact YouFirst on this, once you have checked available seats on alternative services. It's a lot easier all round if there is A bucket availability, so I would check those options first and then call up. I think LAX - JFK would be OK, but only in the same cabin as PHX-PHL. Check also routings via BOS and ORD.
