Back to only operating Tequila Sunrise flights.....
I don’t understand your blocks so using 4 weeks.
44 hours return over 5 days?
44 x 2 = 88 hours for 10 days work.
Repeat 10 times a year = 880 hours per year working how many days? Oh sorry plus sim and recurrent! Actually probably more sim to keep landing currency.
Who honestly would not see that as a sweet roster? As I said I know SQ guys who loved it, and done who hated it!!!
