At most this kind of car seat travel bag protects your car seat from dirt and maybe weather... these bags provide no padding and no support or structure for your car seat so they can be handled appropriately. The best thing you can do is take your car seat on the plane! This is safest option for the car seat and your baby or child! Just make sure your car seat is FAA certified for use on an airplane (sticker on your car seat) But since that’s not always feasible, please get a padded travel bag that actually fits the shape of your car seat and gate check it instead of putting it under the plane. carseat flywithbaby travelcarseat travelbag carseattravelbag newmom baby maxicosiromi fetch faa LTKBaby LTKTravel LTKItBag
