Better to be stuck in MAJ where there are hotels and other facilities than in KWA like some of us were last March. We were guests of the US Army for ~12 hours while awaiting a fixed airplane.
A bit unfortunate they didn't find a way to get a reserve crew to you in TKK; that's not so far from GUM that it would be impossible to schedule it to happen.
Did you try to declare Trip In Vain at GUM and get your fare refunded? That was another 6 hour ordeal on our trip.
