This happened to us a few years back when traveling with friends. Had to divert to San Juan for fuel- we were going to CLT. No one to tell us which line to get in so by the time we got to the front of the line there were no tickets home. Had to fly standby to Hartford. We got on but our friends didn't. Spent the night in a very crappy hotel. Next day their flight went through NY to get to Boston (not Hartford). Of course that was the day that Boston was on lock down because of the bomber thing. Told our friends to get off in NY. Then they had to find a way home from there on their own dime. Would have had to do it from Boston too. Horrible experience. Just curious though, did you have assigned seats for your flight? I always choose my seats when I buy the tickets. So sort of wondering how they can put 2 bodies in one seat??
