Here's what happened to me. They changed my return flight Sat 12/3 by 1 lousy minute and it said on-line I no longer had assigned seats. So tonight I called, I knew they'd be busy, like goofy4tink, I spent about 20 min on hold. Then someone not very customer friendly said that I had no seats on the plane and he couldnt help me and that was that. I paid for these tickets months ago, said he couldn't help me. I asked to speak to a supervisor, I spoke to a nice lady named Kathy who said that yes, of course I still have seats on that flight, they just don't know what seats they are.
