What kind of trouble might be stirred up if I were to book a two leg flight to St Thomas (or anywhere) and a two leg home and then bail the last leg and just rent a car for the final short hop leg due to an overnight layover. Would checked baggage be pulled if the passengers don't show up?
Continental has a great fare from alb-STT, like $350. But there are no late flights that work with the 7:00 arrival of STT-EWR coming home. All are the following morning. To save $150 apiece for 4 people it might be worth renting a car for those last 180 miles.
