From what I understand this is the problem (but someone please correct me if I'm wrong)...I'll use AT for AirTran and SW for Southwest... If you book AT flights through AT, you pay a fee to pick your specific seat. Then, you get your picked seat when you board. Easy peasy, right? Keep reading... If you book SW through SW, then you don't get to pick your seat but no one does so it's not that big of a deal. If your party has children, you'll get to sit together and this will be determined upon check-in. Again, rather easy to understand. But just wait... I *think* booking SW through AT is working out fine but I could be
wrong. The issue is (again, from what I understand) occurring when someone buys an AT ticket through SW. That flight is actually listed on two different websites (SW and AT), one site is letting you pick your seat (for a fee) and one is not letting you pick your seat at all. Well, when the seating is figured out, the people who have picked their seats (and paid the fee via the AT website) are of course given the seat that they picked. This then leaves random seating throughout the plane (2 seats here, 3 there, 1 there, etc.) to put the people who didn't get to pick their seats in advance because they booked through SW. So then, upon boarding, those who booked AT through SW are wanting their party to sit together but theres no room for that because those who booked AT though AT are refusing to move because they paid for their seat. What's the easiest solution? Book AT with AT and book SW with SW. But of course, the prices for these flights are likely different on each site, and with prices of airfare going up and up we all want the best deal.
