How do I complain to the DOT?
I looked into the cost. Of just canceling the Hkg to BKK segment and then paying cash for the tickets. Looks like it'll cost over $1500 to do that (not including any change fee from AA, which I guess should be 0). And that's for economy - I booked business for the award tickets. It's frustrating because there were other award options when I booked these tickets, but now all are gone and I'm left with either a 14 hour layover or spending $1500.
