Information for passengers with disabilities and reduced mobility
You should always be able to use supplementary oxygen if you need to.
Airline policies vary and some will provide oxygen for you to use, but a charge may apply.
If an airline allows you to bring your own oxygen (usually contained in a Portable Oxygen Concentrator - POC) they should not charge you to take it with you.
You should be allowed to carry oxygen in addition to your free cabin baggage allowance.
You must let your airline know, in advance, if you plan to take your own supply with you.
You should always check with the airline and your doctor. Also note that some countries do not allow POCs to be taken with you for security reasons.
Guidance about airline policies on oxygen is available from the British Lung Foundation.
