I've given up on the idea of being on flight 3, the inaugural flight on Dec.18th from JFK to LAX, due to the lack of J availability. However, for those who might be interested, there are J seats available on the inaugural A321XLR from LAX to JFK on 12/18. This is flight 4 departing LAX at 3:20 PM. A one-way ticket in J will cost you $1,850 or 105K miles. I think I'll try to get on the inaugural international flight of this aircraft, whenever that might occur.
