We have a flight that goes from Sacramento, checking in at United, and then a 1 hour layover at LAX then direct to Munich on Luftansa. If we "check in" with United I understand that we need to be compliant with Luftansa's regulations for carryon weight, etc. My question: Does Luftansa even have a place to weight the carryon if you have already been through security? I'd imagine they have sizing box handy.
We plan to hold to the 17 lb.s but just wonder if we were 17 1/2 or 18 lbs. by their scale vs. ours.
