Interestingly if you look at the Full Season Allocation you will see that there appear to be 7 less movements for Cathay in the season.
Thanks Scottie, I should have noticed that.
there are some cancelled flights in May, don't know why, lack of a/c or crew!
If it is absolutely necessary for either of those reasons, May is probably the right month. Last Year, May saw the lowest LF for CX flights, but even then it was 80.4%, which is hardly a disaster!
