What is the highest altitude commercial aircraft fly?

[Bluueyee]

Hello all
What is the highest altitude commercial aircraft generally fly? I know I have been in planes that flew between 25,000 and 35,000 ft. It seems that some international flights are on the higher end like 32,000 to 35,000 ft. Does anyone know if there are any regulations on what the highest altitudes allowed are? Are max altitudes any different for aircraft in Canada?

The Boeing 747-400 has been certified to 45.000 ft, but the limit is generally the legal requirement for the crew to have Oxygen masks donned whenever they are above 41.000 ft.
The supersonic Concorde was the only commercial aircraft, apart from corporate jets, that used to fly between 51.000 and 55.000 ft (depending on weight), but obviously does not anymore!

Flew back from Canada on a 767 at 39,000ft. Apparently there were strong tailwinds at altitude, so (as the pilot put it) we 'took a different route home', taking off from Calgary, heading SE to the US / Canada border, then followed the border and straight across the Atlantic into Gatwick. None of this great circle lark! First time for the pilot too...
