Keep the current system, but include options like letting you see the rankings of airlines within regions, such as EU, North/Central/South America, Africa and Asia.
Won't change much for airlines based in the US, but for European and African airlines it can help, especially EU airlines that can compete with others because of the Open Skies Agreement. No actual benefit of this, but makes the competition side with other European Airlines more interesting.
