Last week I flew from Tokyo to Bangkok using an ANA 78X. I took off, turned on the autopilot, went about my day and came back to my phone in time to land.
As I was reviewing my flight footage (as I usually do to check my takeoff and landing) I happened to stumble on something peculiar: a Thai Airways 777-200 coming straight at me at FL340. I knew I was flying at the correct altitude because I was flying at a southwesterly heading. The other guy was flying towards the northeast, which means he should have been at an odd number flight level (e.g. FL330 or FL350).
Previously, when I saw people flying at the wrong altitude, I didn’t think much of it, but now that I’ve gone headfirst into a Thai 777, my mind is starting to change.
I decided to post this on the community to see what kind of ideas can come from having a general discussion about this.
