kaytieeldr said:NotUrsula makes some excellent points. If a Southwest passenger thinks there's a chance they will be asked to purchase two seats, do that up front. If it turns out the plane isn't full, Southwest WILL refund the second ticket in full. Why subject oneself to potential embarrassment? On the other hand, I know I'm fat. It's not like a Gate Agent is going to surprise me with the news. I DO fit in one seat with the armrests down. Knowing Southwest's policy on Customers of Size, if I choose not to purchase a second ticket, the ONLY person I can blame for any potential awkwardness or embarrassment is ME.
Honestly, if the economy or one's finances are such that purchasing a second airline seat is a hardship, maybe this is the wrong time to be flying anywhere.
My BIL is a large person and he prefers SWA for this reason, he gets more room and they almost always refund him the price of the second ticket. Sometimes even when the plane is full.
