Here's a 190 trip out of Dec's bid.

Day 1- BOS-DCA-BDL-DCA (17:40 in DCA)
Day 2- DCA-FLL-DCA-FLL (13:20 in FLL)
Day 3- FLL-SJU-FLL (11:54 in FLL)
Day 4- FLL-BOS

It appears that BOS has the best 190 trips, it's also the largest 190 base. JFK is 2nd , tends to do a lot of JFK - Upstate NY or PWM/BTV/BOS legs. MCO 190 does more island flying...Get the plane to San Juan and then fly around on the island hops.
