Where OLIWW is going wrong on Thurs is that the ACE flight changes from 1030 to 1505 - 0125 (Fri) in the peak period and on Sat. the AGP flight is not 1540 but 0800 -1200 in the peak period.
Doing the calculations by timings this needs 4 aircraft with 5 spare full rotation slots.
Mon... 1605 -
Tues.. 1505 -
Wed.. 1505 -
Thurs. 1605 -
Sun... AM - 1605
My calculation seems to fit in with Air Humberside
