I usually use my old coach legacy. It was my first designer bag I ever bought. I love it because no logos on the outside, perfect crossbody if needed and side pocket for easy grab of map, etc. I should say was my go to bag. Now, not sure if it would work with the littles and we haven't flown with them all yet. For now though it's nicely stashed in her dust bag and will come out for air in a month or so for her massage (leather conditioner).
