I would say that this week isnt a good week to look at these things. Simply since most flights into & out of The Northeast were cancelled yesterday, some on Sat others this morn. That everyone had to be rebooked and that would have taken away any availability and possible cheaper fares.

that being said one can usually get a cheaper fare if its at least 7 days out, but that also depends on the mkt. A flight to FLL for yesterday was $168 last Sun, after 1am (it was then Mon morn) it went up to $218 , since there wasnt a 7 day advance any longer. good thing I decided for other reasons not to go. We had alittle snow here in NY yesterday. Of cause with JetBlue flying there also from EWR it helps to keep the fares down.

since it seems that you are from CLE , Id check fares out of Akron, Toledo, and even DTW. It might not be on CO but you might beable to save some $$$
