Whenever I have had an airline and looked at the competition on a route, the highest number of tickets available for any competitor seems to be "9". Yet I look at LF from the statistics page and some of my competitors are only 75% full, others 85% whilst I am 90%+ and it shows that I have more tickets available than them ?

Only 9 tickets will be shown to competitors. So you cant figure out the exact loads but just get a rough estimation.

Reminds me of websites like booking.com, which will keep saying "Only 9 seats left available! Book immediately!" forever. ^_^

Ah right - makes sense, so does "9" mean 90% empty do you think? Because they range from 3-9 normally. Must be a formula behind it :))))))))))))

Nope

I’d assume, it means at least 9 seats are still empty. If it’s less, then it’ll show the number of empty seats.

Absolutely correct. This is standard airline practice in the real world. If it is not your airline, you can only see if the flight is full (0 seats available), almost full with an actual figure (1-8 seats) or has 9 or more seats available (shown by a 9). If it is your own airline you will see the actual seats available as this is not commercially sensitive

Comes from real world reservation systems, where availability of 9+ seats will show as 9, anything less will show as real number. No big science or conspiracy or complicated formula into it.
