Actually, every airline will have the option to harmonize or not with the one to fifty. That includes Air Canada. We are not really saying that Air Canada won't.
Let me give you an example. In Germany, Lufthansa operates many types, including Boeing 707s, 727s, 737s, and 747s, McDonnell Douglas DC-10s, and Airbus A300s, A310s and A320s. Under similar regulatory requirements, they chose to standardize their fleet equipment so that they fall within those three types and therefore went through the one-to-fifty standard. They are doing very well and are more profitable.
Every airline company in Canada will have the option to harmonize. It will be strictly up to them, based on their load factors, the type of aircraft, and whether they can combine the types to make that decision.
