There are a number of airlines that fly out of the UK and connect in Iran.
Using Skyscanner.net we were able to find airlines based in the European Union which fly to Iran. We have reached out to each of the airlines to find out what their policy is on gay flight attendants who fly to Iran and whether LGBT crew can opt out of flying to a country which could potentially execute them because of their sexuality.
There are a number of countries in the world that outlaw homosexuality and at least 10 of which have the death penalty for homosexual acts.
The airlines which will be flying to Iran from May include: Air France, Alitalia, Lufthansa and Austrian Airlines
A spokesman for Austrian Airlines said,
All our crew members are informed about local traditions and laws. Furthermore, we of course do not know about private details like sexuality of our crew members. If a crew member does not want to fly to a certain destination because of reasonable personal reasons, this will be considered within his roster.
Compared to Air France, Austrian flights to Iran are very popular among our crews, there are no complaints regarding headscarves or the like.
Air France, Alitalia and Lufthansa have yet to respond to our request.
