Flew SW from Little Rock to MBJ last April. Connected over Baltimore. All flights departed on time, and arrived early.
Probably the smoothest trip to Jamaica yet. Packrat is correct on using the SW credit card. Usually can get a 50,000 bonus
for signing up. If you travel on the right days, that close to two round trip tickets.
