Post-dive activities must not include going to altitude or areas of low pressure. While diving after flying is fine, flying soon after scuba diving is dangerous. If there is any excess nitrogen in your blood system, going into an area of low pressure will allow the nitrogen to escape into your tissues or joints.
Can you fly within 24 hours of scuba diving?
The Divers Alert Network (DAN) recommends a 12-hour minimum surface interval before flying, and the Professional Association of Diving Instructors’ (PADI) Flying After Diving guidelines say divers should not ascend to a high altitude within 12 hours of completing a single dive or 18 hours after doing multiple dives ( …
How long should I wait to fly after scuba diving?

What happens if you come up from scuba diving too fast?
If a diver ascends too quickly, the nitrogen gas in his body will expand at such a rate that he is unable to eliminate it efficiently, and the nitrogen will form small bubbles in his tissues. This is known as decompression sickness, and can be very painful, lead to tissue death, and even be life threatening.
What altitude is safe after diving?
So the standard advice rings true: don’t fly or go beyond 300 meters or 1,000 feet for at least 24 hours after your last dive. And if you’re planning to dive in mountain lakes above 1,000 feet enroll in an altitude-diving course.
