I used mine for our flight to North Carolina recently. It was pretty convenient. I strapped it around my waist and then my DS sat on my lap and strapped on to me. You can also use it on chairs etc. I think next time we fly most likely my DS will be too big for it, so I figured I would sell it if anyone else needs it. It's made by One Step Ahead and retail price is $29.95. It folds up into it's own little pouch which you can just keep in your diaper bag. Send me an FM if interested!
