It is. Being a pain in the ass when faced with jobsworths, we were once told we couldn't have an item of hand luggage on a TC flight because it was 7kg. "No problem" I said, "That's her (Steph's) bag and I have no hand luggage at all - so we're 3kg under!". No, not acceptable - 5kg maximum per item.
So I literally took a carrier bag from inside the 7 kg bag, filled it with half the contents of 7kg bag, she weighed both, and printed our boarding passes.
I then, to make a point, happily put the carrier bag of things back in the original bag (on her check in desk right in front of her eyes), thanked her and off we went with one 7kg bag. Ridiculous but true.
