Have you tried again today? Even though they have told you their position, sometimes their position changes as the storm gets closer and they are more likely to rebook you without the charges if there are seats available. Although the way the airlines have been right now finding seats might be the bigger issue. I remember for Matthew, prior to the storm a lot of incoming flights were cancelled to keep planes from being at MCO in the storm and they closed the airport and flew out the remaining planes out to avoid damage, so when the airport reopened while people had trouble getting out, most people coming in that were booked on an after storm flight seemed to have it pretty easy as they needed those flights to work to get planes back to MCO to get people out. Although this morning, the way the models are looking isn't good, and looks like there is a potential for a lot of wind damage in the Orlando area. The path can always shift again though, so who knows. With an inland area, a slight shift can make a major difference as to how strong your winds are.
