We fly from Buffalo too. We paid about $170 round trip in December on SW. Both ways were nonstop- early flight down, evening flight back. I am still waiting to book for early May. Right now the early nonstop is $157, evenings are 157 & 132, so round trip would be almost double our Dec prices. There are some $105 flights, but they are late flight down, early flight back. SW seems to have changed their strategy about pricing.
We book SW or JetBlue, they have the only nonstop flights to Orlando from Buffalo. JB changed their times, their nonstop is no longer early morning. Their flight to Buffalo is now the early morning flight & then they return to Orlando & get in there at about 2:30. Those times seem to waste both my arrival & departure days, so we won't book them, even tho we prefer JB over SW. SW does have several nonstops every day. I just need to get my mind around the increased cost this year.
