I've just done this for myself. I flew last week, and I'm flying again next week.
I don't have a prescription for Oxygen. Even if I did, you can't take NHS oxygen out of the country, so it wouldn't help.
We'll come to the actual oxygen in a minute, but first you need to speak to the airline.
Google the airline name, plus the word "oxygen" and you will find the airline webpage about special medical needs...
They all have different policies (see below for more), but in every case, they need some form of medical form or letter which proves that you have a medical need for oxygen, and that you're broadly stable - medically speaking.
So you will need to see your GP for this letter.
I found my GP very happy to do this - I just rang their receptionist and I emailed the forms from the airline. The GP filled them in, scanned them and emailed them back.
Or just go and see your GP. The hospital told you that needed Oxygen to fly. They should have also sent a letter to the GP saying this. If they didn't, I'm sure the GP would believe you if you told them you had already been advised of your need for Oxygen when you fly. You're not asking them for the actual oxygen, just for a letter. At worst you may need to ring the hospital clinic that told you needed Oxygen to fly and ask them to send a note confirming them to your GP. Their is probably a clinic nurse you can call. Look at letterheads from the original appointment letter.
Your hospital visit in July to find about "supplemental oxygen" is - I think - talking about whether you need oxygen generally, rather than just when you fly. "Supplemental" just means "extra". So, on the plane, it won't be extra to the extra you already need! So I don't think your appointment in July effects you flying. You can arrange things now.
When they say you need "2 litres" of oxygen, I'm sure they mean you need 2 litres *per minute*. This is a "flow-rate" and is the setting for the oxygen you take on board. This is a very standard amount, it's what I need.
So what about taking oxygen - how do you get it?
British Airways seem to be the only airline (I could be wrong) that will let you use the oxygen bottle already on the plane. This is free and super easy. I did it myself last week. They treat you like royalty, letting you board first and they take extra care of you on board (I got an extra mini bottle of wine...!). You sort it with the "Pre Clearance Unit" as part of the process when you get their form filled it (the oxygen, not the wine...).
For everyone else, you will need to rent and bring your own oxygen. Taking actual oxygen bottles would be cumbersome and complicated, so I'd suggest you don't try and do this.
Better to take a "P.O.C" which is a Portable Oxygen Concentrator. This is a battery-powered machine, which compresses the air from the cabin and extracts the oxygen for you, meaning you don't need any bottles. Super easy.
Speak to someone at healthoxygen.com/rental-inf... (as also linked to by StoneUK above). Sarah there was really helpful to me, very kind and knowledgable. Expect to pay around £250 per week for a machine. Not cheap, but they are thousands to buy.
- Don't wait for July appointment.
- Find your airline's policy on oxygen on-board, and ring them to find out what they need to know.
- See your GP to get their form filled in, or get a letter (depending on what the airline needs). Send it to the airline, if required.
- Speak to Sarah at healthoxygen.com about renting a P.O.C. machine. They also need a letter from your GP. Whatever you got from them for the airline will probably be enough.
- Now you have clearance from the airline, and a P.O.C. machine to take on board.
- Enjoy your holiday!
I hope this is useful. Don't worry, it's all very straight forward. Reply to this message if you want me to clarify anything!
Some airline info:
Easyjet just need you to bring a letter certifying that you need the oxygen and that you are stable generally. You can show this on boarding, and you don't need to tell them anything in advance.

Others, such as BMI (0330 333 7998) and Jet2 (0800 408 5591), advise you call them up, at least 2 days in advance, to let them know. They also have forms to fill in.
British Airways have a form you need to download and have your GP fill in. They say 7 days in advice, but I did it with 24 hours notice and they were super helpful.
