Strict cabin allowance?

Im travelling UC for the first time next year and I’m just wondering if It will be problematic if I have a cabin bag that is maybe 1 or 2 cms too big? The height is fine but the width and/or depth is too big? Any experience and advice gratefully received.

Thanks

Welcome to V:Flyer

I very much doubt anyone will say anything unless your carry-on is noticeably larger than usual. I’ve certainly never experienced Upper Class check- in staff at any airport pay much attention to my carry on.

Thanks so much I was just concerned that the dimensions were a guide to how big the overhead locker is and that being slightly over the allowance would mean the door wouldn’t close. Thanks avain
