The really big problem is that your flights are too close together. They should be a minimum of 1 hr apart, and instead they are 30 minutes apart. That means the LF gets penalised, that's why it is so low.
I assume that is 5 planes, flying the same route 3 times daily each?
If you change them from starting at 0400, 0430, 0500, 0530, 0600, and instead make them start at 0400, 0500, 0600, 0700, 0800, there'll be no more penalty.
If your CI is lower than his, that also won't help.
You've also got 68 HD seats in each plane? That hurts too against a competitor with standard seats.
But neither of those things is as big a problem as flights being too close. Fix that, and you'll probably be ahead on market share, and LF should probably climb above 60 or 70%.
