Answer:
If you already know that you will need oxygen onboard during your flight then you can bring your own supply.
You should ask about bringing oxygen when you book your flight and you can do this by contacting our contact centre by telephone.
Please contact customer contact centre.
Oxygen can be carried in gas canisters or air cylinders. Liquid oxygen is not permitted onboard.
The canister/cylinder cannot excede the maximum weight or dimensions for permissible hand luggage, and the gas pressure must not excede 3000 PSI.
It is not possible to book this via email or online.
