Thursday at 1:55, I can go online with Air Tran and do the online check-in. My question deals with seat assignments. We have 2 family groups flying together , one family of 4, one family of 3. Do we choose seats, or are seats assigned? Is there any chance we will be able to sit together, or can we forget it? I can't imagine they would have my children sit seperately from an adult-could they? I'm getting nervous about it... Any help is greatly appreciated!
