'KB' I think you will find that the flying public don't give a stuff about flying time they just want to know how long it will take to fly from A-B once they are strapped in. When the door is closed to them that's when the clock starts ticking!
'ccysam' would be spot on as would 'CW', 40 mins flight time & an hr elapsed time from sit down to get up on the AY-SY run! The 'cattle' just want to get there & as fast as possible, 30 mins is dreamtime !
