Has anyone taken any of those $39 flights out of Portsmouth, NH? We fly out Thursday, but I just wanted to see if anyone had any experience with parking, if there are delays, etc. We don't have assigned seats -- how early should we be there? Anyone get a rental from Alamo in Sanford, and find the counter not open since arrival is after 9 p.m? These are my worries!! Thanks to anyone with information, and Happy Holidays.
