In seven years with the 744, I've never been able to climb higher than FL 410
Same here with 4 years experience. However it is not unusual to always be at FL410 at the end of a flight with a light load.
If my memory serves me correctly, my beloved 742F had a ceiling of FL450. The sporadic empty shuttle flights I flew from Hong Kong to Manila was flown at FL430.
Lemurian,
is there hype pertaining flying above FL400? I always thought it was always who flies the biggest plane
