Frequency benefits for LNB and SNB on LH flights do not stack. In other words, A 752 x3 daily vs 1x daily 772 will be seen as a daily 752 vs daily 772. That should remove flooding a LH route. At least as far as NBs are concerned.
I was trying to get this across. That on certain routes, frequency
would "disappear" as a factor completely, and pax allocation would be a function primarily of capacity
. So if a route calls for a 772, and one airline supplies it with a 772, while another supplies it with 2x757, the 2x757 would be treated as one larger aircraft (~772).
The end result de-emphesizing frequency and allocating by capacity is that all the airlines would have very similar LF.
So as far as a way to achieve this, some combination of:
- "remove benefit" (of frequency)
- "add penalties" (for narrowbodies, and techstopping
My preference would have been majority of the deisred effect to come from "remove benefit" of frequency, and only minority of the desired effect to come from addition of penalties. With that approach, long thin routes would have been only minimally affected.
