This has never happened to me before--I was seated on a fairly small plane (2 seats on one side, 1 on the other) out of FAY and I had gotten on standby in order to have a longer connection in ATL, so my seat wasn't guaranteed in advance. But as we were just about to depart, they told me I had to get off again because the plane was too heavy. Does this happen a lot? I weigh 115 pounds--my checked luggage another 25 maybe. How do they calculate this, and why could they not know before I boarded that this might be an issue? It sucked to be all excited to have gotten on the flight and then I was so disappointed to have my hopes dashed and spend another 4 hours waiting in the FAY airport for my original confirmed flight. I assume I deserve no compensation since my seat was never guaranteed, right? Is this a common thing that happens?
