Travelling with oxygen Some people with pulmonary hypertension (PH) need to take oxygen therapy. If you need oxygen therapy and plan to travel by plane, you should tell your travel agent or airline before you book your tickets. Most airlines are able to accommodate people who need oxygen. However, different airlines have different rules and some may charge you extra for carrying or supplying oxygen. Because of this, it can help to shop around to find the best prices. Some people with PH may need oxygen when flying even if they don’t usually need it. It is therefore worth arranging oxygen, even if you think you may not need it. We have compiled a list of the airline rules on oxygen for people who need oxygen on flights. If you need oxygen cylinders while you are away from home (in the UK or abroad) you will need to organise this well in advance of travelling. Your oxygen supplier will be able to provide more details on this. For more information about obtaining oxygen while away from your home, visit FAQs: the oxygen supplier page.
