Oh yeah, they were loaded alright, all 2000 of them, on a 777, if you think thats bad, there's still another 2000 to be sent to other parts of the world. Anyone can see the "left overs" when boarding from Gates 1A or 1B. I had the privilege of working on a night shift when the disruption actually occured, not a pretty sight. I've never seen First class passengers walking about in their PJ's before.
Worst case i've ever experienced is a passengers (correction, First class passenger's) bags being tagged to Lagos when he was off to Dubai.
