Currently flying NZ to UK with Korean Air and am delighted with their service treating our bikes as checked luggage but in Seoul was called to transit luggage where they had spotted a CO2 cartridge in my gold bag. They asked to open it in front of me and insisted on disposing if it before my bag could be sent to London despite it having already flown in from Auckland! Not a big deal but this could result in bags being delayed or not arriving. I wonder if they will spot the other CO2 cartridges in London Heathrow on its way to Manchester?
I think I’ll. it risk it in the future
