This appears to be an old thread, but to keep from starting a new thread I'd thought just use this one. We are gate checking our stroller (Uppababy Cruz) and want to use a bag for it, just to make it easier for both us and crew to handle/move. The one that Uppa baby makes specifically for this model of stroller is pretty substantial and therefore, substantially expensive ($100+). For those that do use a bag, do you have a recommendation? I'm not looking for armor plating here, just something to keep it from flopping open or the fabric pieces, like the canopy, getting smashed or caught onto things as the crew brings it back/forth down to the hold.
