The Civil Aviation Authority, which regulates the industry, estimates that pilots are flying 30% more hours than a decade ago but maintains the "finest flight time limitations system in the world" means fatigue is not an issue.
Roger Wiltshire of the British Air Transport Association, said pilots are flying well within their regulated flying hour limits.
"Although short haul pilots are flying more hours than they were that's because the schedules are more efficient," he said.
Well as someone once famously said "They would say that, wouldn't they?"
