My flight has been creeping up on Delta... however, it is difficult to tell now, due to come changes they made to flights, and that will likely drive up the prices...
We were booked at $203 each RT from Cleveland to MCO 1/31 - 2/5 That price has been fairly stable, but they have changed out flights twice (, once each way by combining multiple flights into one) Now there are fewer seats left so, the prices will likely start to climb. I ended up using those flight changes to negotiate better flights out of other cities. (I really want to do a connecting flight in the south due to the winter weather). I ended up on a much more expensive flight, without having to pay the difference. However, that flight has gone up every week for the last 2 weeks also.
Initially I thought I let my excitement of planning force me in to buying too early, but it seems clear that early was at worse an OK decision, and might even turn out to be the best decision.
