Health issues and flying
What to do if you've been SCUBA diving, or are at risk of DVT.
This page tells you about certain health issues you should be aware of when you fly, including Deep Vein Thrombosis, or flying after SCUBA diving.
Important: If you have an existing medical condition, this may be affected by flying, so please read this information carefully to find out what you need to do. Our Special Assistance team can help make sure you're cleared to fly.
For most of us, flying is a safe way to travel. However, the pressurised cabin can potentially affect passengers with existing medical conditions, people who have recently been SCUBA diving, and people at risk of Deep Vein Thrombosis (DVT). See below for further details. If you’ve had a general anaesthetic or dental treatment within 48 hours prior to your flight, you won't be able to fly.
Please be aware that our cabin crew may spray insecticide in the passenger cabins at the start or end of some flights. This is harmless to humans. You can find out more information from the US Department of Transport.
