A few years ago I was involved in an interport race in Hong Kong. The visiting team (from Ireland) were not allowed to take their PFDs on the flight. I forget which Airline (either BA or Cathay Pacific.
The small Co2 canisters are not too expensive and are readily available, have you considered removing the canister and purchase a new one on arrival, a bit of a nuisance but will avoid problems with the airline.
How odd. I thought I posted a comprehensive reply to this but don't see it. The gist of my reply
was that the carriage of C02 inflated lifejackets as passenger baggage IS permitted, with the
approval of the operator (airline). The current (42nd) edition of the IATA (International Air Transport
Association) Dangerous goods regulations refer. From memory Sect 2.3.4. which deals with
'Dangerous goods' as baggage. Again, from memory, I believe 2 additional 'spare' cartridges permitted
per passenger. The bottom line is call the airline and quote the above if you get someone
not sure what you are talking about! I recently travelled from Heathrow to Hong Kong with a PFD as
hand bagagge and after security checked with a supervisor, I was let through no problem.
Definitely best to get prior approval just in..............
