Just for fun I looked at AA.com and found airfare 4/17 thru 4/24 for $309 roundtrip. If you have any flexibility, the cheapest days to travel vary but are often midweek. I also get frequent fare updates from free services such as Airfare Watchdog. I fly from NYC and am usually good at finding cheap flights. I use a credit card that gives me miles so I accumulate air miles quickly. This past December I was able to do my roundtrip for $130 by booking two 1-way flights, using air miles one way and a voucher. Even without the voucher, my trip would have been $230 - still not bad. You still have some time before you have to panic. Watch the fares closely and see if you can find a trend.

Good Luck !!
