As far as I can see, this itinerary requires me to spend the night at JFK both ways; quite unappealing or is there a decent solution available? Cheap hotels near JFK maybe? Lounges at JFK seem to be closed at nights.
Also, no upgrades to business elite on SEA-JFK for medallions and v.v. even though the current business elite on the 757-200 is nothing to write home about (no flat bed seats; Delta must be crazy to demand premium prices for a fancy pillow).
Please let me know if I'm mistaken.
