JetBlue's chief executive agreed to halve his salary on Monday in a show of solidarity with employees as the low-cost carrier struggles with soaring fuel prices and a slowing U.S. economy.

David Barger, who took the helm at JetBlue last year after founder David Neeleman stepped down, is to have his base salary cut to $250,000 from $500,000. The cut only applies for the six months from July through December, according to a regulatory filing.
