Here's more travel fun. I recently was looking at airfare for the week of May 17'th - 24'th (2014). Jacked up expensive vs. a couple of weeks or so later. Finally decided to try to book on Orbitz.
I probably went through 8 to 10 Orbitz listings, and every time got a yellow bar telling me something to the effect that the airfare market is volatile and the flight I just tried is no longer available. Did this again and again and again, I'm telling you.
A day or two ago I tried again, just out of curiosity, to book 1 (wouldn't have gone through with it; just wanted to see if I could book one) and nope, got the same response. I could understand maybe the Orbitz system messing up a day or so, but this was probably a couple of weeks or so later that I tried that one more time.
So there were a lot fewer options than I thought.
At least you're booking so far out that you shouldn't have that problem.
Richard.
