Fun was trying to book a Y-Up fare Mon afternoon and then trying to select seats for an hour only to have it do one of: barf, Tell me I was booked in I Class and not bring up seat maps, or just pretty much ignore anything I tried to do. The seat maps when brought up were apparently completely wrong as they didnt show any of the occupied seats. Of course getting so far as to put in airport codes was also a challenge earlier. Co.com phone support was so busy they apparently pulled the tech weinies to answer the phones - to which I wondered - why weren't they fixing it instead?
