Boeing 737 fleet Every aircraft in the Lynx fleet is the very latest iteration of the ultra-reliable 737 family. These planes have advanced aerodynamics, highly efficient engines and upgrades to the airframe and flight systems.

Before ceasing operations in February 2024, Lynx Air operated a fleet composed exclusively of Boeing 737 MAX 8 aircraft. As an ultra-low-cost carrier (ULCC), Lynx chose the MAX 8 specifically for its high-density configuration (typically seating 189 passengers) and its fuel efficiency, which was critical for their business model of offering rock-bottom fares. At the time of its shutdown, the airline had nine of these modern jets in service, with dozens more on order from Boeing and various leasing companies. Following the airline's collapse, these aircraft were quickly reallocated within the Canadian market; most of the leased fleet was picked up by WestJet, which already operated a large number of 737s and could easily integrate the "ex-Lynx" planes into its network with minimal pilot retraining. Air Canada also briefly utilized some of the aircraft to fill capacity gaps caused by delivery delays. While Lynx Air itself is no longer flying in 2026, its "dauntless" liveried planes helped prove that the 737 MAX 8 is the preferred workhorse for the low-cost sector in North America due to its reliability and competitive seat-mile costs.
