AirHelp, a company that assists passengers on Europe flights in filing claims for flight delay compensation, has launched a global airline ranking based on data it has gleaned from 235,000 claim filings.

The AirHelp Score ranks 27 airlines on the pace at which they accept and pay claims, as well as on the frequency with which, at least in AirHelp's view, they wrongfully reject claims.

The score also factors in airline on-time data maintained by FlightStats and quality performance ratings developed by the Skytrax website. On its own website, AirHelp breaks down how each airline has been judged in the different categories.

AirBaltic topped AirHelp's initial ranking, followed by Austrian Airlines. Delta and United are part of a four-airline tie for 10th, and American is part of a two-way tie for 14th. Portugal-based carriers TAP and Sata tied for last.

The ranking does not include Southwest or other U.S.-based carriers that don't fly to Europe. Under European Union regulations, ticket holders who are denied boarding, whose flights are canceled or whose flights are more than three hours late on arrival are often entitled to compensation of between 250 and 600 euros.
