How to Keto on Travel?

Hey guys. I need some recommendations. I travel internationally a lot for work. I started keto and IF in late December and all has been well staying at home. Starting in February I start my trips to Japan and China. What recommendations do you have to survive the long haul flights in coach? The box lunch they provide is mostly carbs. Also I’ll take any ideas from experience Keto-ers on what to eat in China and Japan. I feel like this is going to be hopeless.
