Why is it illogical ?
It`s been said often before that slots start low and will grow over time to cope with the illogical situation that aviation service starts with a bang some day at 0:00 everywhere in the world with some hundreds of airlines.
Itīs also coded this way to slow growth overall. It would be quite illogical having some mega-airlines right during first year.Or having airports with 120 movements per hour without the technical equipment to handle this traffic in the 50s and 60s.
Evidently itīs still too easy for a lot of airlines to make money to acquire aircrafts and opening routes that airports run out of slots so fast.
Itīs that same discussion about Heathrow over and over again.This problem wonīt be solved until CBD will be introduced (you can use another London airport), connecting traffic will be coded (that way you decide where people change planes), and there would be a significant number of players being content with a perfectly managed smaller airline outside of LHR,ORD,ATL, LAX and NRT.
Also in real life LHR is producing headlines because itīs limited and everybody wants to fly there. BA and some big Americans still defending it against political plans to close it for a bigger new airport east of London, I guess, because of the exact same reason everybody wants to get in here, too.... being in means monopolizing your routes due to lack of competition....just because of the lacks of slots.
