I thought there was alot of weight restrictions on summer Asia flights out of Calgary which limited cargo revenue hence 1 reason for the new runway.

I have also heard that at peak times the US rush doenst allow for more slots and choices at those times for carriers.

Remember also, a longer runway adds to the safety aspect of landing in bad weather etc. Of all the Airport Authorities I always thought Calgary ran a relatively effective airport. Especially with 0 government money going to the airport. They charge who they should for air travel, the people who use the airport.
