low LF until a second A/C added

[Mr.HP]

Hi,

I'm wondering if anyone has the same situation like me?

I started the first route to A, the demand is 320 pax/day with no competition. The route served by a SB20 with 58 seats. Average LF was about 60%, CI and RI at that time were 30 and 55

The first route had the LF of 60% for quite a long time. Then I added the second SB20 route, and both of them have decent LF. The average LF of the first and second are 78% and 72%. CI and RI now are 33 and 68

Can anyone explain what happened and why is it like that?

Thanks
