Saw this oddball departing off a rainy Runway 4 after I dropped my fiance off at LGA early Saturday morning: A BahamasAir 737-400 (N42XA) leased from Xtra Airways (hence the XA on the tail), flying to FLL as Spirit 705.

Apparently she's been doing this run for a couple of weeks but I guess the 645am scheduled departure is too early for anyone to have noticed. I know Spirit has been chartering some interesting metal to add capacity, but this might be the best one so far.
