Just found a strange display for some of my routes. I am running a route with 2 classes (Y and C) but for some days, it shows 0% for F class in the route history like below:
Route Date Load factor
VHHK - RJAA Thu, 22-Jul-93 Y: 95.1% C: 90%
VHHK - RJAA Wed, 21-Jul-93 Y: 94.1% C: 100%
VHHK - RJAA Tue, 20-Jul-93 Y: 91.2% C: 100%
VHHK - RJAA Mon, 19-Jul-93 Y: 99% C: 100%
VHHK - RJAA Sun, 18-Jul-93 Y: 97.1% C: 90% F: 0%
VHHK - RJAA Sat, 17-Jul-93 Y: 93.1% C: 100%
VHHK - RJAA Fri, 16-Jul-93 Y: 94.1% C: 100% F: 0%
VHHK - RJAA Thu, 15-Jul-93 Y: 91.2% C: 100%
Not sure if it was asked before.
