Giving these guys a rating of just one star is being super charitable! We started at Kayak to purchase airfare to Sydney, Australia. By the time I paid for the tickets, I discovered that Kayak had pawned us off to Vayama which Ive never heard of before. Too late, monies had already been sent. Then the problems really began. TWO weeks BEFORE we were scheduled to leave, I called Vayama to see if we could upgrade our Qantas seats to premium economy. The agent politely asked if we were aware that our final segment home was cancelled. I said no and asked when were they planning on notifying us? I received no reply. They said they had to send this up to the ivory tower and would hear something within 48 then 72 hours. ONE week later, they provided us with a flight changes. We tried to obtain seats and after researching American and Qantas, we determined that Vayama had somehow obtained two different record locators for us, one being an impossible route. We called again to notify them of this and an agent confidently indicated we didnt know what we were talking about double locators were impossible. She said shed send this up to the ivory tower again. THREE days before we were to leave, Vayama emailed us to indicate that indeed we had two record locators for the same trip and that between them and American Airlines, they determined the best approach would be to leave well enough alone and to struggle through our seat assignments at the airport. Well never use either of these travel agents again.
