Also note typical WN fare sale rules: no Sunday travel.
FL does not seem to have this rule....I would expect carries to either match this lesser restriction or match carrier for carrier--ie, non FL destinations will be restricted to WN fare rules but FL destinations will be more lax.
Lastly--from Houston, I'm seeing some FL fares through June 1...not sure if they're just spectacular attacks or whatnot...the fares don't quite match the sale amount, but BUF, ROC, and WAS are standouts here, with a successful pricing of a WAS ticket at 199ai a few minutes ago.
