Air Canada is mulling to buy more aircraft to support its fleet and is just reportedly close to deciding which from Airbus or Boeing it will enter the deal with.

A spokesman for Air Canada said the company will make the announcement as early as next week. At least 100 new aircraft will be involved in this purchase acquisition.

Citing unidentified sources, AirWise said Air Canada's acquisition will be done in two phases.

The airline may opt for 30 or more jets immediately by placing firm orders. Options for up to another 30 as insurance against a faster than expected upturn in the economy may likewise be put in place.

This shopping spree could result to a worth of US$6 billion.

Air Canada, starting in the spring of 2014, will begin taking deliveries for the first of its 37 Boeing 787 Dreamliner aircraft on order. These aircraft have been eyed to replace the less efficient Boeing 767 aircraft in mainline Air Canada's fleet. It will be put in place to service Air Canada's low-cost subsidiary, Air Canada Rouge. The transfer will help improve the Rouge fleet over the next several years.

Moreover, the airline company is touted to place additional orders for the slightly smaller category of jets at a later date.

Air Canada for its major fleet was said to be deciding between Airbus for medium-haul jets, and its revamped A320neo version, or eventually transfer to the Boeing 737 MAX.

The Canadian flag carrier has already brought five new Boeing 777-300ER aircraft. Deliveries are expected in early 2014.
