Hi 4Nana, I've just been watching their patterns lately... They won't open up availability again until August 15th probably, long time off for sure... It seems they release availability 4 months prior to the last day of their current schedule....
I'll tell you though there have been no good fairs out of the Northeast lately... We got our Delta tickets months & months ago on a day they seemed to drop to 167.00, we had credit & got them for 99.00/rt... I guess we'll stick with them even though I'd love to add one more day to our trip it doesn't look like it's going to be possible... I have SWA credit & I was hoping they would have a reasonable fare & I could just take the credit on delta... Guess not!
If you haven't already done so, go over to travelocity & sign up for notices on your airports, so you know when the price drops!
