I checked in at Budapest as I usually do with Lufthansa with the same roll aboard I always used. Weighed in at 11.1 and forced to check it through to JFK. I asked when the weight rules were effective the checkin desk said always. I checked with delta sky miles team and they are 12 kg minimum before saying checkin. Also I did know Lufthansa is too cheap to allow for priority security line. Last time I fly Lufthansa anywhere. If I want Ryan air rules I will fly them for one tenth the fare to Frankfort. Be aware of this before booking Lufthansa.
