I also have to say southwest was awesome for us. Feb was my first time to use southwest and go to disney in a wheelchair. coming home we had to change planes due to a problem, we were already on the plane and we had to get off. Since my wheelchair was going to be loaded on another plane, not only did they bring me their wheelchair they also did all the preboard stuff for us for the new flight.
The butt level was yuck lol. I told my husband that is the only issue I had with using my wheelchair.
I had to take my wheelchair through all the ride lines and the CM's were great when we were clueless.
At the airport in orlando: my wheelchair went off so they gave it a good check but they also made me get up and be body searched. The lady doing the search kept apologizing, a little humiliation there but they were just doing their job. They said some times the machine malfunctions.
