I've made 4 round trip reservations so far this year, and all have been buggy, the best case I described above. The other three giving no opportunity to call up existing reservations. I'm starting to lose faith.

I'm losing faith because it seems like there are dozens of airlines out there with functioning websites. I'm not talking about making super complicated transactions. It would seem proven programming to simply recognize your reservation code and last name and pull up the data.
