I fly frequently on Southwest and have experienced time changes but usually only a few minutes difference, however last year I had a flight on a Friday from providence that was suppose to go to Raleigh thru BWI with no plane change. We got to BWI and were told to get off plane and go to gate 4 for instructions. We didn't have boarding passes as this was suppose to be no plane change. When we got to gate 4 no one was there and we were told there were no flights till next day. I was going for a wedding the next morning. I had to rent a car and drive the 10 hrs to Raleigh airport and pick up my bags in the morning. Terrible treatment for the 24 people who were suppose to be on original flight. I got the one way flight back but not the cost of the rental car booked one way last minute. So southwest was pretty shabby to me and I'm a frequent flyer with them. We have had this happen again and my husband would not get off plane unless one of the stewardess's accompanied us to next gate .
