About 90% of the time for me it’s too cold. I’m the one sleeping in 3 blankets with at least 2 scarves over my face. It’s also an issue I’ve found to be a lot worse on BA than other carriers, and most of my routes for the past year have been 777.

Its the second reason why I’d choose another carrier over BA (first and foremost choosing the most direct/fast/best timed route for me).
