Are you taking on the peaks and have to transport your airbag backpack by plane? Find out in advance (minimum 15 days before) if your airline accepts airbags.
Consult IATA regulations (International Air Transport Association) on their website www.iata.org, section 2.3A concerning hazardous goods.
If your airline does not accept airbags then it's mainly due to the gas cartridges. Depending on your destination, you can choose to travel without the cartridges, however if you do so then make sure that a sports store on site will have the right cartridges. If this makes the outbound trip easier, you need to comply for the return.
How to prepare your bag for your plane trip:
Unscrew the cartridges and deactivate the system by pulling on the handle.
Screw in the cartridges, close the zip and attach the inflation system using the Velcro.
Caution: do not transport unscrewed cartridges.
Print the IATA documents (table 2.3A) and place them in your airbag backpack.
Put your airbag backpack in your travel bag.
Check in your travel bag at the airport.
Do not use your airbag backpack as cabin baggage.
Transportation regulations related to transporting cartridges are available on the following website: https://www.iata.org/en/programs/cargo/dgr/
It is strongly recommended that you keep a copy of the IATA guidelines with you so you can show them to the airline staff at any time.
