Two-thirds of the 3,500 mainline airliners, regional jets and turboprops in service with low-cost cost airlines serve the two prime and mature LCC markets - North America and Europe.

 LCC fleet share

Data from Flightglobal's ACAS database in this year's Airline Business interactive special on low-cost airlines shows that the size of the fleets in these two markets is similar, with North America just edging Europe at 1,200 units against 1,186.

The Airbus A320 and 737 families are the low-cost work-horses, accounting for 84% of the global budget carrier fleet. The 737 Classic and NG families are the most popular, with a combined 61% market share.

The A320/737 order backlog splits four ways thanks to the emergence during 2011 of the re-engined A320neo and 737 Max families - the former also bringing Pratt & Whitney back into the short-haul fold in force for the first time since the demise of the JT8D-powered airliners. But CFM remains the dominant supplier, with an 86% share of the current A320/737 fleet and 67% of the overall backlog.
