I was traveling with a companion that utilizes a scooter to get around. We have flown together many times and used other airlines. Southwest by far is the most accommodating airline in the fleet your staff Makes the accessibility easy and convenient for for this type of travel. We would personally like to think the flight teams of our two flights for being very accommodating and helpful throughout our trip.
