American Airlines pilots have voted overwhelmingly in favour of striking, despite claims from the airline that negotiations are still in progress.

The vote was announce Monday. No walk-offs are imminent. Federal law makes federal airline worker strikes difficult to pursue, according to the Wall Street Journal.

According to the Allied Pilots association, which represents more than 15,000 American Airline pilots, 99 per cent of the vote was in favour of authorising a strike, with 96 per cent of its membership participating in the vote.
