When I know I pass thru United club fly grab n go at IAH (they have freshly squeezed oj), I bring a small paper bag, because I’ve never seen staff giving bags proactively, and I don’t see many people putting food into their bags. But a full size empty carry on?? There’s always bigger fish.

If she had a whole family in tow, and she was gathering food for them, then the amount could end up being reasonable per person basis, but if I were her, I'd be too embarrassed to do that, and I'd let all of my family members to pack their own small paper bags.

Maybe they should post yet another sign, and a carry ‘out’ sizer, similar to bag sizers at gates?🤭
