Flitegirl - you might perhaps spend a large part of the first 24hrs sleeping, however you then have another 30 hours to spend some of your US$250 (this is a minimum Dixons-son)... and layovers are a minimum of 54 hours...
IF there is a MEL return eventually, crew will be rostered a maximum of 1-2 of these per month...
Days off (9 per 28 day roster period) are all at home base...
There will be NO standby downroute - this is now official...
