Flying back from a brief work assignment in Dubai, I decided to have a gin and tonic to help me relax.
I happened to be flying over Iranian airspace at the time, while it was also 7am in London. Thus two rules were very thoroughly broken. However, I think an early drink is acceptable when one is flying. It helped me sleep for much of the flight. It was also definitely past 5pm in Sydney.
Finally, it got me out of some hefty reading, so that’s another good point. So cheers from the Middle East!
