EWL,
Are you sure that someone didn't just press a few wrong buttons when trying to add the new SYD-OOL schedule to the system? Do the old flights have to be deleted first?
Problem seems to be fixed by now (Thu), the new schedule has a couple of daily 763 flights (are these the all economy 767s?) and the rest 717s. Interesting one of the 717 flights only operates on Tue,Thu,Sat,Sun, but I can't find what sector this aircraft does on Mon,Wed,Fri. Any ideas? Also Mel-Ool will have 5 x 717 flights/day as from late March.
