Here is the one I purchased. I was pricey but I now think I can make it all day in the park which I haven't done in the last few years.

I searched far and wide for a cover so I could put it on an airplane to no avail. My problem was I couldn't get adequate information from American on whether they could baggage check it all the way through to Orlando. Online they had a good description on how to gate check it but I learned my lesson flying through Charlotte in October. DON'T GATE CHECK anything. I never have less than an hour connection BUT if your plane is late getting in you could be moving as fast as possible from the end of terminal E to the end of terminal C and SOME OF THE MOVING SIDEWALKS WERE NOT WORKING. It was miserable. I missed my priority seating so had a long line in front of me to board and was sweating and breathing so heavily the flight attendant was concerned and brought me water.
Anyway, yes they can baggage check it.
I'll let you know how I make out. It came fully assembled and easy to use.
