What I do is pick what airline or airlines I would like to fly for my trip. THen I go to their web site about 3 times each day and check my flights. I have been doing this for about the past 3 weeks. I also did this last year when we went and we got a 130 rt fare. You just never know when these low fares are going to pop up and they usually don't last even a day so if you are pretty systamatic about checking you should be able to find a good rate.
