Oh, I just ran into this.

I went online and researched tickets last Friday for my trip in mid-February. I picked out a few different flights, and brought them home so FH and I could decide which one we wanted.

Yesterday (monday) I logged back on, and the price had gone up OVER $100 dollars each! I called the airline, and they said that one of the connecting flights had sold out, that's why it went up so much. So we had to take a different flight.

I wish I'd just bought them on Friday!!
