On my last EK 413 flight I noticed the entire cabin had female FAs. FA walked me to 1A asked if she could get me anything and I cheekily said "I'm disappointed there are no male crew in this cabin."

A few minutes later she reappeared and introduced me to a male FA and said "He will be working the bar at the back and will be delighted to look after you."

So yes, EK is LGBQTI friendly.
