Now, the question is, should I fly standby, or pay for a change fee? I want to fly standby for the flight to MCO but risk not getting a seat. Right now, there is a lot of seats available in Economy, but couldn't that change due to the fact that it's a popular travel time to Florida? The problem with a change fee is risking about whether the seats sell out or not. What do I do if there is a delay and all of the nonstop seats sell out?
