In the last few years, engine technology has improved significantly for narrowbody aircraft. The competitive nature of the current short-haul U.S., European, and Asian domestic markets have airlines competing on cost and efficiency to offer the lowest possible ticket prices to their customers. The single biggest direct cost on almost all routes is the fuel that the aircraft burns, and burning less fuel is always better. Frontier Airlines is one of a few Ultra Low Cost Carriers (ULCC) in the U.S. that has been aggressively pursuing a modern, fuel efficient, all economy-class fleet to complement their ULCC business model. They are a U.S. launch customer for the Airbus A320neo (or New Engine Option) family of aircraft and also operated some of the first commercial flights with the CFM LEAP-1A engine. I was lucky enough to ride on one of these shiny new aircraft and talk to the flight crew about how it is changing the way we fly.
