What happens if you fly with low oxygen levels?

Lower levels of oxygen in your blood may make you feel unwell or could even be harmful to you during or after your flight. This means that, even if you do not usually need oxygen, you may need it while flying. Additional oxygen keeps the oxygen levels in your blood at a comfortable level and keeps you safe.
