(Reuters) – Elliott Investment Management has informed Southwest Airlines that it is requesting a special shareholder meeting, Bloomberg News reported on Monday, citing people with knowledge of the matter.

The hedge fund has launched a campaign to oust the carrier’s CEO, Bob Jordan, and other top executives, blaming them for the company’s underperformance.

It wants Southwest to change the way it runs its business and has laid out plans to replace two-thirds of the board’s 15 directors.

Elliott and Southwest did not immediately respond to Reuters’ requests for comments.
