That happened to me, too, but our prices went up astronomically. We are going in January and I had been watching the prices since about mid-July. They kept fluctuating up and down a little, the lowest I saw was in early September - $489 RT for 3 of us. The next time I checked it was $595. I could have kicked myself for not buying at the lowest, but our dates weren't absolutely firm (didn't know about husband's work) and I didn't want to take chances. By the time our dates were firm, the prices were $630. So I decided to just hold out a wee bit longer hoping it would get below $600 again. Less than two weeks later, it was at $1070!!! I called the airline and she said it was a supply and demand type of thing. There were only 7 seats left on the plane, so they were charging more. Needless to say, we've changed our dates to a week earlier and I bought tix immediately for the $630.
