Why the height in feet?
By the way if you want to fly a nice airline Air Canada was really great and the US customs in Hawaii and Calgary were first class.

All airport temperatures are in Celsius everywhere. I've found that at a lot of airports, pilots have a choice of looking at Metars or the old SA's. many choose the latter which gives temperature in Fahrenheit. But at least we have the choice. On another subject, recently flew on Lufthansa, in their inflight magazine all articles in English use feet and inches which irks me, I had to refer to the German side to get metric units. Same goes for the airshow, moving map display with altitude temperature and distance on it. I'm writing to complain. Believe i already complained about this last year.
