Transporting Lifejackets on Aircraft
We are occasionally asked if it is OK to take inflatable lifejackets on commercial aircraft
IATA publish Table 2.3A regulating the transport of dangerous goods which states that:
Subject to prior approval
from the airline, self-inflating life jackets are permitted if they contain not more than two small cylinders with a non-flammable gas in Division 2.2 plus not more than two spare cartridges per person.
They are permitted as: Carry-on baggage Checked baggage On one's person
Not all airlines follow these rules, so consult with your airline well in advance and also allow additional time for check-in."
