So says someone whose experience of long haul flying is whether they feel like eggs or salmon when they are woken at TOD. Next time you hear ‘We are about 30 minutes from XXX where the temperature is XX. We hope you got some rest during the night...’, remember that the person saying that quite likely hasn’t slept properly in at least 36 hours and could most probably throw up at a moments notice through fatigue. And - will be doing the exact same thing at the opposite end of the clock in about another 36 hours time. After dealing with various domestic and training issues in between.
