Not too long ago I took an airplane to the West for business and it was the most superb and nice flight I suppose I have ever taken in my life. Everything about the flight was wonderful, which was not very common for an airplane. The one thing especially that was shockingly good and contributed to the wonderful atmosphere was the fact that the central a/c device on the plane was perfect. It is not often you will have good a/c on a plane. Usually the a/c is murky and horrible, and you are actually fortunate if you can even breathe fantastic air quality. But on this flight both the air quality and the a/c device was nothing short of perfect one hundred percent. You never actually know what you are going to end up with when riding on a plane. And I just got extremely lucky. I do not expect to be on another plane anytime in the near future that has such superb a/c. And on the flip side, I do not see myself being on a plane that also has enjoyable air quality, but great air quality and good a/c are the keys to ideal indoor comfort. Sure you can have excellent air quality and good a/c in a household or place of business, but to have good air quality and good a/c on a plane is just something that really doesn’t happen all that often. So never expect it. If you enjoy it, just be thankful and consider it a bonus and a lovely surprise compared to the norm.
