I had an award ticket for mid-December ANC-SEA-MSP-MSY with the first two legs on AS and the last one on DL. Today that set of flights disappeared and were replaced by ANC-SEA-MSY, all on AS. That was not an option when I booked it, even though the SEA-MSY flights had been loaded. Anyone think it odd that AS has dropped my DL award flight? Just sayin'.......
