That's a separate issue. The frequency bonus needs to be addressed, and the best proposal on that is Jona's proposal, in my opinion.
Jona's proposal is that the frequency bonus be changed so that "appropriate" aircraft size for a given distance could not be overwhelemd by smaller, less appropriate aircraft for the distance. He has different distances and sizes, but if you take just one example, say > 3000nm, the appropriate aircraft would be a 300 seat aircraft. So if airline A flies 1x300 and airline B flies 2x150, airline B would get credit for only 1x300, not 2x150.
I like Sanabas' proposal better, but I understand and would welcome Jona's as well...
Regardless, I think everyone agrees that frequency needs to be fixed. However, until frequency does
get fixed, I don't know if I should support changes that make it easier to dump frequency on routes. Allowing more planes at a base certainly would enable more frequency dumping, which is why I'm not too excited about the prospect.
That said, once frequency and other competition related problems (mostly having to do with pax allocation) get fixed, I would happily support unlimited aircraft at bases.
