Found these today:
PBI-PHL has only
$270 Anytime fares inside seven days.
PBI-MHT has $99-$104 flights five of those days (x7, and too late to buy for today). During the week #2623 and #1141 are direct with a stop at PHL.
PBI-PVD has $104 flights two of those days, with connections at PHL.
No time to write a proper thread intro today; will try to add it later. Also wondered whether it should be the Official Hidden City/Custom Connection/Alternate Airport thread. I consider BWI and PHL alternate airports, and four or five of the FLA airports as viable alternatives to each other even though southwest.com does not.
So for example, here are some alternate airport options:
FLL-PHL is
$275 Anytime inside seven days.
FLL-BWI is $72 Thu-Sat ($59 one week from tomorrow).
MCO-PHL still available at $79 today, $59-$79 every day in the seven day window.
MCO-BWI has a couple days at $99, Thu-Fri at $54.
IIRC, if you look at the routing on some of the FLL-BWI flights, there are hidden city deals available by booking one of those connections and getting off early.
