We flew Allegiant this week and the couple that flew with us paid extra for exit seats. There was a plane change on the out going and incoming flights. We went from an MD80 to a B757. The exit rows don't match up, so they were told that they could not have an exit seat even after paying for it. They were given no compensation or other recourse just TS. We hope they can get their money back, but good luck with that. I say that because this week my son had to change his flight dates and it took him 6 days and several hour each day to get to talk to some-one at Allegiant to change the dates.
