Never been to this airport - Flying southwest PUJ to BWI to RDU - I have two optiosn 1hr 40 min and 2 hr 55 min as layover options on a sunday evening - Will be traveling with an almost four year old- so that always takes a tad longer (getting stroller plane side, etc) - how long do I usually need? thinking of leaning to the longer layover just to be on the safe side, although I hate waiting in airports?

thoughts?
