This past Sept (slow time of year) we saw people at the AirTran desk raising holy heck yelling that they couldn't believe Air Tran would separate their families and when told the flights were completely full, were demanding that other people be moved. They were told in no uncertain terms by AirTran, that since they had had the chance to pay for their seats and chose not to, there was no way AirTran was moving people who did choose to pay the money to pick their seats.
They were also asked why if it was so important for them to sit together, why didn't they choose to pay the $6.00. However, they were then told that once they got on the plane perhaps other passengers might choose to give up their seats, if they were asked nicely and if not, the FA might be willing to ask for assistance for them, but they were told that if people refused to give up their paid seats, that they would not be forced to.
Your friend is going in June, during a time that plane will be full of vacationing families with kids. I would not be expecting those families who paid to sit together to give up their seats for a family who chose not to pay. Sorry. Also flights seem to be flying completely full these days. I know my flights in Sept and also in Jan were completely full and they were asking for volunteers to fly on later flights. With all the kids out of school, and everyone vacationing, that situation is only going to get worse in the summer. I'd be afraid that if I didn't have an assigned seat I'd be the one involuntarily bumped.
Even people who are not with big families often choose to pay for their seats, because they like to be in a certain part of the plane. I know I travel down there solo several times a year and usually choose to pay for my seat, because I don't like flying and want to be as close as possible to the front, and will not sit in a middle seat, and don't particularly like window seats. I have no problem paying to get my favorite row 13 aisle seat and have no intention of giving it up. As soon as my neighbors (in the middle and window seats) get seated, I put my eye mask on and try my best to get to sleep to avoid thinking about how high up I am
. I have flights booked on Air Tran for both my upcoming May and my Sept trips. This time I have decided to pay for seats only on the flights back. For the flights down there I am hoping to get a seat in those first few rows that they open up at 24 hours. I know it's a gamble, but one that as a solo I am willing to take. If was going with family (even adult family) I would not be willing to take that chance. For my flights home, I will not have access to a computer 24 hours from my flight times, so chose to pay for my seats and got an aisle seat as close to the front as I could. Sorry, but unless I get a comparable seat (an aisle close to the front) I am not moving. My feeling is that family had a chance to purchase seats just like I did and chose not to. If it wasn't important enough for them to pay the $6.00 to assure they were sitting together, why should it suddenly become important to others.
