Poster tube carry-on?
 

Does anyone know if AC will allow a 42" poster tube as carryon on a US-bound flight? I can't run the risk of them forcing me to check it in at the gate.

I've never had a problem domestically, to the US, or to Europe, and I do it a fair bit. I would be very surprised to hear of you having problems with a poster tube as carry on.

I've seen many come on board. The challenge is whether passenger security and screening will allow them through. Generally, they do.

The only issues I've had are once through security at LHR T2 and once when an EI agent decided to get a bit uppity and try to tell us what security is going to let through (of course he was wrong).

But AC was great with it. Both domestically and internationally.

And most of us are happy to stow them in forward cupboards (space & size permitting), on request.

I have transported them over 20 times with no problems at all.
