TRAINSPOTTING author Irvine Welsh took a pop at American Airlines after his flight was delayed by almost two hours.

The Scottish author vented his frustrations on social media after his jet was unable to leave because the airline had 'lost all the updated flight manuals from our iPads.'

He later tweeted saying the problem had been fixed but the pilot was waiting for it to download on his ipad and compared the incident to, "a Mission Impossible films but with only the crap bits left in."

He later joked: "Ain’t no party like an @AmericanAir party!"

The airline apologised to the author and fellow passengers tweeting: "Thanks for hanging in there."
