• US carriers fared poorly in the study with none cracking the Top 20.

After years of battling it out for the title of Worst Airline in America, Spirit and Allegiant now find themselves near the top of an even more dishonorable list: Worst Airline in the World.

"Our fares are 'unbundled,' meaning that the base fare does not include the cost of amenities such as checked baggage, in-flight entertainment, priority boarding, or seat selection," an Allegiant official told Insider via email.

Allegiant's no-frills approach results in lower operating costs and customer savings, according to company officials.

"Most of our flights are under four hours, which doesn't allow enough time for meal service that may be offered on longer international or domestic flights," Allegiant said.

Allegiant doesn't offer in-flight entertainment. "The equipment adds weight to the aircraft, which burns more fuel," Allegiant said. "That increases the cost of operating the flight."
