Available slots decay
« on: August 27, 2018, 05:03:03 pm »
I've noticed an effect where it seems like, very frequently, if you don't immediately use slots granted by an airport expansion they slowly "decay", or if you free up slots they slowly go away. This is at an apparently fairly steady airport loyalty, etc.

Even if this is due to modestly declining loyalty, could this effect be moderated somewhat? It's extremely annoying to be forced to "lock in" slots the moment you do a possibly extremely expensive expansion, or cut back on one route.

Yeah, I've noticed this as well. Assumed I was doing something wrong...

Yeah sometimes I'll have negative slots so that they actually disappear as soon as I free up slots from a certain route :/
Thought that was a bit odd.

Maybe it's that since the slots are given on a basis of the airport's view of our airline relative to other airlines, they're decaying because of lack of relative local passenger/service quality growth as more airlines start to make routes there?

I figured it out, the primary cause appears to be airplane decay and maybe service quality decay.

I do wish there would be a warning before cancelling slots if we would just lose the slots.

Is there a general level where it is wise to replace old airplanes? Not sure if there is a threshold in the code or not, though my performance seems to get much worse below 60%.

40% is a hard cutoff where you have to replace planes or their performance falls apart precipitously.

I've been working on quantifying the value of condition above 40% to see if a renewal % higher than that is justified. Condition has a surprising number of effects throughout the game so I may well find that it is worth it, although my initial calculations suggested 40% was optimal. (They had some bugs, though.)

Let me know the result ;)

I dun even know that myself kekekeke

one thing for sure tho, if it goes below 40% it's going to get ugly

Yes in long run, the dominating factor when it comes to slots is loyalty

Loyalty is based on 2 things - passenger volume and service quality to that airport. If i remember it right, it takes the "lower" of the two. So if you have high enough volume, the determining factor is going to be service quality

And yes, service quality is affected by airline overall service level and airplanes conditions.  :D

Giving warning on losing slots upon lowering frequency is probably a good thing to do. An easier thing that i could do is make available spot to go negative to indicate that the airport is offering less slots than before.

Noted the issue thanks  :D

For your own hubs, in practice it's based on quality 100% of the time. So increases in flight quality directly and proportionally increase your slots.
