Not flown recently, but 3 1/2 years ago I wasnt charge anything to fly from YVR.
One thing to remember is clean your bike like you have never cleaned it before, they wont allow any foreign dirt in. I nearly missed my transfer to Christchurch while they jetwashed my bike with Dettol.
It’s now 1 or 2 x 23kg depending on ticket. Gold, gold elite and koru you get an extra 23kg. Not lenient any more sadly but I can get my hard case and a bag through on 2 x 23kg. This was from 2 weeks ago. Am in wgtn but all bikes too big sorry
