We are Canadian's and not familar with this airline but because we are a border town we decided to fly from the US to Orlando instead of our usual airport in Canada. I notice that airtran has very cheep flights but concered with the check in. Does this affect us sitting together. I have younger children and if it is between sitting together and paying more money, I will just suck it up. Also is it a good airline. Could someone ease my worries?
