Air Canada recently launched a pass program similar to cellular telephone plans: It lets customers prepurchase a set number of flights in the U.S. and Canada at a fixed price. Some plans are targeted to vacationers heading to Florida or Hawaii; others to oil workers commuting to work for three-week shifts into northern Alberta. Big companies can buy as many flights as they want, usable by as many as 300 employees within any three month period.

Some big U.S. carriers are eyeing the program with interest.
