I was checking their website every 2 hours at work. Noticed the price drop for our dates in July around 2 pm. For our desired times (early am, late pm return) price was 215.15 per person with the 5% for booking on the website. This is the lowest price I have seen for our times. Called my fiance and he said go for it. I went back to book 5 minutes later and price had jumped to $250. I went to Orbitz and found the flights for $225 (the first price I had plus the 5% discount). I called USAir to see if they could match it. I was on hold about 10 minutes. She said no, in this instance they couldn't match. I went back to Orbitz and tried to book it. It was GONE! So I tried the next latest return time, which I then booked. I was mad though, even though the times are pretty much what I wanted, I really wanted the 9:20 flight. Plus, I ended up losing the 5% discount and having to pay orbitz's service fee.
I have been stressing about airfare for over a month though, so it is somewhat of a relief that I finally have tickets that I know I can afford for the times that are pretty close to what I want. I was hoping to get them cheaper, but I didn't want to risk the prices skyrocketing again (which they ended up doing today). So, my advice is, if you see a rate grab it. Even 5 minutes to call your significant other may be too long!
