With any luck, the fatigue levels will go through the roof. It needs hundreds of pilots to go fatigued as it’s only when BA start cancelling flights due to shortages will they recruit more. I’m astounded at how many pilots soldier on flying 5 or more trips a month. On long haul, that would probable mean 5 nights out of bed without any sleep. Is that really how we should be operating aircraft in the 21st century? 2 pilots across the Atlantic overnight, without any rest? Controlled rest doesn’t really cut it i’m afraid.
