I have noticed an interesting pattern with my weekly LF and PAX.
In weeks when my LF is high, my PAX is low and vica-verca. It doesn't really make sense, however when I looked into it, the weeks when this was happening was when I had b-checks or a lot of c-checks happening, hence my overall capacity is down. But... the reduction in capacity seems to be counter balanced by the fact that a lot of my flights go to the same destinations - albeit well spaced throughout the day. So the reduction in capacity for certain 'heavily utilised' routes on the weeks in questions seems to be counter balanced by a large increase in LF in the planes that are flying. Makes sense - its the only reason I can think of anyway. The effect still seems quite large considering when flying to the same destination, I have been careful to space flights throughout the day.
Anyone have a similar pattern, experience?
