Two years ago, I had a flight from OKC to Houston that had to circle for a bit due to weather. We ended up landing in Dallas to refuel, and by the time we had done that, we could fly straight to Houston and land. A day later, I got an email apologizing for the inconvenience with an attached $25 LUV voucher. I was shocked. Southwest isn't as stingy as some people claim, and I certainly don't think that I was owed anything. It was completely weather.
