Is there a weight limit and size limit? I can pack my carry on till it holds 35+ lbs and it still fits the size requirement. No problem for me lifting it into the overhead.I'm in London now, and am travelling Europe only with carry on that meets the size requirements. However, my bag (25lbs) will have to be checked due to the low weights allowed for carry on. Check with the individual carriers for the limits, but it was a shock for me for how little I was allowed to take compared to most US flights.
