Airplanes can have different size cargo doors, depending on the size or type of aircraft. Check with the airline in advance to verify that your motorized wheelchair or scooter will fit the plane.
Colon, the second largest city of Panama, is a port town that features a duty free shopping district and access to the Panama Canal. While definitely worth the visit, Colon can be difficult to access for the physically challenged traveler, as one must utilize ground transportation to see more than just the portside shops. On our visit to the canal, we were able to see two ships pass through the locks, which was an amazing sight.
