This is the best summary I could come up with:

Air Canada is slashing six major routes out of Calgary this winter, in part due to an industry-wide pilot shortage that the carrier says threatens its "overall operational stability."

The country's biggest airline confirmed Wednesday it will no longer offer non-stop flights from Calgary to Ottawa, Halifax, Los Angeles, Honolulu, Cancun, or Frankfurt as of the end of October due to ongoing fleet and crew constraints.

A pilot shortage has been brewing across the continent for several years due to a variety of factors including an aging workforce and the rapid proliferation of new discount airlines that are putting pressure on the labour supply.

Also this year, WestJet acquired Sunwing Airlines and folded it into its main operations, a move some critics have said will mean less service and higher fares to sun destinations from Western Canada.

John Gradek, who teaches at McGill University's aviation management program, said of the six cities Air Canada will no longer offer as non-stop connections to Calgary, Cancun and Honolulu are a surprise.

In an email, WestJet spokeswoman Madison Kruger declined to say whether the airline would increase its service offerings in Calgary as a result of Air Canada's move.
