ABS IN PLANES
ABS avalanche airbags are generally permitted aboard an aircraft according to the general rules of IATA (International Air Transport Association). However, as the IATA regulations are only a framework every airline and every country is free to pass stricter regulations.
You always have the option to bring your ABS backpack only and look for an ABS dealer at your destination who offers the rental of ABS cartridges and handles for the time of your stay. Here you can find an ABS dealer at your destination where you can rent an ABS backpack or an activation unit.
The US American Transportation Safety Administration (TSA) will not allow your pressurized cartridge on board. Discharge (activate) the gas cartridge before entering the airport. Only once your cartridge is fully discharged, unscrew the cartridge head from the cartridge and put both in re-sealable plastic bags. Carry them through the TSA security checkpoint so they are visible to TSA personnel. Afterward, the cartridge head can be screwed back on the cartridge by hand. An ABS dealer at your destionation can replace the empty cartridge for a new one.
When flying to or from Canada (without stop in the US) we recommend that you inform the airline about the ABS TwinBag and provide the extract from the IATA table and the data sheet which describes the content of the cartridge and the activation handle (Download on the left side) before booking your flight.
It is very important that both the cartridge and activation handle are checked in together with the ABS TwinBag. Please print the section from the IATA table and the data sheet and attach them to your ABS backpack. This is to ensure that the purpose of the cartridge and backpack is obvious to the airport staff. If you check in the cartridge and activation handle separately, they may be confiscated!
Extract from the IATA table
"Avalanche rescue backpack, one (1) per person, containing a cylinder of compressed gas in Div. 2.2. May also be equipped with a pyrotechnic trigger mechanism containing less than 200 mg net of Div. 1.4S. The backpack must be packed in such a manner that it cannot be accidentally activated. The airbags within the backpacks must be fitted with pressure relief valves."
All ABS cartridges and activation handles starting from the double airbag models are compatible. For this reason, you also have the possibility to take your ABS backpack only and look for an ABS dealer who offers the rental of ABS cartridges and handles.
