i haven't tried this carrier brand, but to put your mind at ease - we travel with the airlines a lot (united a few times) and no one cares about your carrier, sorry to say. they won't check it at all. as long as it zips completely closed and fits under the seat you're fine. the height dimension is the one to worry over, if any, because sometimes you can end up on a smaller plane with less clearance underneath. i'd recommend a soft, pliable carrier for that reason |
