Out of curiousity, how many times have you guys had your carry-on luggage weighed? I actually never have. The closest I came was in LHR a couple weeks back when the ticket agent asked me to lift my bag so she could see how big it was, then said fine. This was in T1 connections from Europe and there was no scale there so I don't think she could have anyways...but I'm just wondering how strict they will with the carry-on weights...
