I spend so much time on this forum - sad life , but I love it!
It’s about 96cm so yeah, that sounds right and you are limited to 60cm on most airlines. In August, I flew from SanFrancisco to Zurich with just a longboard which was 100cm long but only 2 cm in depth and it just went on top of all the bags in the cabin so no one cared. With a complete, you can’t do that but maybe, you’ll be lucky cause it seems like most of the time, not many care but there is always that 1 person that spoils the whole thing.
Ohh, to answer your question, I never tried because I never knew what to do with it if i wouldnt be allowed to carry it on.
