IMO the pay per rotation at airports should be the same for all airports. The number of paid rotations should be the differentiator between categories.
This way everyone is incentivized to fly everywhere (even cat 1 airports), and larger airports retain the potential to earn more due to their capacity to handle higher weekly traffic.
Vote for this idea here:
Hi @Karim-CTO-SimFly Any updates on the changes to CAT 5 - 6 - 7 payouts?
When do we plan to roll out this changes?
I like this idea; I completely agree.
The category should influence the number of flights allowed, not the payment.
Furthermore, there are other adjustments that airports need. For example: SEQM is the airport in Quito, the capital of Ecuador, and in SimFly it’s a Category 3 airport. SEGU is another airport, also in Ecuador, in Guayaquil, and in SimFly it’s a Category 4 airport.
SEQM has better infrastructure and more actual traffic than SEGU. The runway is longer and is being expanded.
Both airports should be Category 4 or even Category 5 if we compare them with other Category 5 airports in SimFly. But it’s a matter of properly adjusting the categories; the opinions and information that the community can provide will be very helpful.
I’m just giving one example, but there are many similar cases in SimFly.
Many airports in China that are currently in low SimFly categories are being expanded. This needs to be taken into account when updating each airport’s SimFly category. For example, ZGNN appears to be nearing Category 5 status.
I also think that changing category once the airport has been already purchased wouldn’t be a good idea, but, of course before buying an airport anybody can decide that simfly could raise the airport price 
, or why not, lower it..
Thank you @StarVen
I have also submitted this () as an AMA. Please vote for it if you have not already.
It’s also worth considering the possibility of paying the difference in value for the category, but subtracting the cost of the levels achieved. Of course, this wouldn’t make any sense in categories 5 and above; the difference would be enormous.
Hi @StarVen , a year ago i made the same question in the AMA for another airports with the same problematic. They answered me that if the airports are already been bought the variations is impossible. For airports that are still in the Bank of Simfly you can send a support ticket with the analysis and the motivation for the change of category and then they will evaluate.
I hope i was helpful, have a nice day.
Roberto once explained in the video, long long time ago. That, this could be possible and will do it for free. (I’m sorry I couldn’t find the clip since long time ago.), if there is(are) enough reason(s) to support.
Ex: some airports, CAT3, later expands its infrastructure, adding runway, terminals IRL., so what StarVen proposed was interesting, that the owner pay for the different (to be fair to both Simfly & airport owner), but should less than the original price of CAT4.
This also rewards to the CAT3 owner too (or another CAT), that he/she has a vision, study and well-planning to acquire the airport before it is developing IRL.
Hi, we will proceed with the changes this week. I’ll let you know as soon as they are implemented.
