J.L. Childress Univeral Gate Check Travel Bag for Strollers and Car Seats - Extra Large Airplane Travel Bag, Red

If anyone is confused about what this product is, it is essentially a giant bag. It has a drawstring to close the opening, and it has handles sewn into it so that you can carry the bag. It also folds up into itself so you can store it away when not in use. I used two of these on a recent trip (one each for a stroller and car seat) and thought they were great. Very important note (and is in the description) that these are primarily intended for checking at the gate only. If you check these with luggage normally, the bags (and their contents) are much more likely to be damaged. Even with gate checking, the bags did end up with black scuff marks and some minor holes. Some people will say that the holes indicate an inferior product, but honestly, it's just a giant bag. I interpret the dirt and holes to be more indicative of the way in which all baggage is handled and stored, and I'm thankful that the bags prevented my items from being covered in that same dirt or getting scuffed up. Highly recommend this for people who are flying. It makes handing off these items for gate checking very easy.
