Terminals complicate things too. Looking at LHR in AE, it can have five airlines with 200 gate terminals and the other 200 normal gates. It means that its not restrictive enough in my opinion. AE's LHR would have built over most of Hounslow and Southall by now, which is obviously not realistic.
Some people probably like the idea of being able to build over Southall so perhaps there should be a separate gate system for realistic and open worlds?
I suppose that's another issue.
Some time ago, didn't someone announce the development of runway slots (un1, I thought)? This seems better to me as there'd then be a fixed cap that could not be breached (we could possibly have some airports "opening" a new runway (airport led, rather than airline led) - give each airport in game its runway capacity and a number based on how many more runways it could have, i.e LHR would be low as its hemmed in on all sides pretty much, but something out in the desert could be much higher. New runways could be "requested" and built after a given number of airlines register interest). If runway slots defined things, an airline could have a terminal with capacity bigger than the runway capacity. But that wouldn't have to be bad, why not link excess terminal space to the forth-coming "on-time performance" feature?
This may be very hard to implement, but would probably be as close to realism as you could get. For example, in my games, I'd have to be more like BA. Instead of having a mega hub at LHR, I'd have to put some flights out of LGW or STN.
Just a thought.

The thing about that is that Heathrow is an anomaly. It's one of just a handful of airports worldwide that are truly slot restricted. Even at some of the busiest airports in the world, airlines can typically schedule flights as they please assuming they've got somewhere to park the plane.
Sure, I suppose every airport has runway limits, but few are close to breaching them. Acquiring places to park and load planes is usually the the bigger concern for airlines. Therefore, I think gate and terminal limits would probably be more realistic.

My results were...226, 26 over the limit. There are also a shocking 166 gates used in JFK. (this includes terminals)
This means that there actually isn't actually a strong demand for gates.
However..that will change as Moldova has announced that he will provide us with accurate gate numbers for various airports for AE3.1 (which will help to create a more competitive environment for gates), now for my required input of this thread (just input on foreign airports).
Limiting 5 gates at foreign airports, while not be realistic prevents people from fatally flooding other peoples hubs from just one country, at most the limit should be upped to 15 but not anymore as I would fear that it could cause airlines based completely on the international sector to go bankrupt, from one airline based in a completely different country. There are airlines that are indeed based in only one market, country 1 to country 2 and if an from country 2 airline floods every flight he runs the airline in country 1 will go bankrupt, which while allowed is other than horribly embarrassing, not that realistic. It would however be realistic if 2 or 3 airlines were apart of this, and one of them from country 1. That is the whole reason why I implemented the 5 gate limit. I have myself never passed 5 gates in a foreign airport before, as my number of hubs never exceeds 5, so I don't know how it feels to be unable to operate flights to a certain airport from all my hubs for reasons other than market & supply (or distance).
Now as for landing slots I was going to implement, I went in way over my head and caused an amazing amount of destruction of various pages trying to implement it..a fixed cap on landing slots rather than gates is what airlinesim has and what I hope AE inherits when timetabling is implemented. As for my opinion on this thread in general, I think 5 is good, but the power in the end is with Yuxi.
(oh and Brit, the gate systems for realistic and open worlds are different )
Now for airports in the countries you are based in...
Honestly, I would think loosening them up a bit is better, however my opinion on these is, I don't really care, I can live with the current system and no other option really intrigues me as being better. (Although yes, the current system is unrealistic)

May I ask why?

I guess you never played airlinesim, anyways instead of picking departure and arrival time on a list, you pick it on a timetable of when runway slots are open!

Right. My point is that's not very realistic for 99.9% of airports. Even at mega-airports like Atlanta, airlines can schedule flights any time they please. The limiting factor is finding a place to park the plane.
Yes but gates are smaller than runways, thus airports can build them a bit more freely.

As it stands currently, the situation is this: UK airlines have an advantage over my US airline on flights to the US. This is because I must operate all my flights from each of my hubs into just 5 gates at LHR, while on the converse routes, UK competition can operate from unlimited LHR gates. So if I have 5 hubs in the US, I effectively have 1 gate per route from the US while UK operators can have up to 5x the frequency to each of my hubs. The advantage is clear when they can operate 767s twice for each 747 and charge a higher price because they need fewer pax to fill the route. Basically, the nation with more 'hub-able' airports is at a disadvantage against the smaller nation.
This means that the 5 gate limit handicaps airlines that run into it. The airlines it handicaps most are those based in China, US, Japan, UK, Canada and Germany. This is because each of these nations has sufficient traffic to fill up 5 gates at foreign airports. While other nations have as many airports (India, Brazil, Russia, and Indonesia come to mind), they don't have the demand to where the limit comes into play (whether by geography or economics).
The primary issue here is that the major airports of each nation are protected for domestic carriers. As it stands, with just 5 gates at LHR in AE14, I have 5% of total LHR traffic and the largest carrier has only 7x the passengers.
A cursory review of the rankings suggests that the handicap against these nations is needed and that raising it will increase the disparity between the highly competitive (but very profitable) nations and the smaller nations.
The practical argument in the game environment aside, the limit is very unrealistic. My info may be out of date, but at one time, BA and United were the #2 carrier at JFK and LHR respectively. In LHR, Terminal 1's 40-odd gates and additional plane-stands are operated by Star alliance members--United alone operates 11. Granted, they also utilize each gate minimally--because most TATL flights arrive between 6am and 1pm GMT, it is inconceivable that a single gate could be used for 7 daily departures on 767s, 777s, & 747s. Maybe the way to approach this is increase the limit, but use one slot for each 30 mins of turn time (so a 744 would need 4 slots while an ATR could just use 1)--or even express gate utilization as hours per day rather than slots.

United might or might not have been the 2nd largest carrier at Heathrow back when they snatched up Bermuda II rights, but they only operate 7 or 8 flights a day out of that airport nowadays. As far as I know, they're not "operating" any gates over there. They have a stake that enables use of 11 of *A's common use gates in terminal 1. British Airways owns Terminal 7 at JFK, but for our purposes, they only have a handful of flights.
Realistically speaking, apart from certain open sky agreements already implemented, AE could cut the limit to 10 slots (1 gate) and cover all but a very small handful of international airlines schedules outside their borders.
There has been discussion of gate usage going to a time based system as well as gate sharing, but I don't know if Yuxi has any plans for it or not. When timetabling comes out, I'm personally hoping for a "no more airplanes at an airport than gates" (plus a few slots for standby fleets and what not).

In searching, I found multiple images with 5 AA and 4 UA aircraft visible in the same picture. We come back to my point that the 5 gate limit isn't realistic, but it makes game play much more reasonable.

...you might be able to find a picture with all 8 UA flights parked at 8 different Heathrow gates at the exact same time for all I know. That doesn't change my point.
Those gates at Heathrow don't operate and work anything like gates currently operate and work in AE. Showing a picture of UA with more than 5 aircraft at Heathrow at the same time doesn't mean AE needs to allow more than 50 daily flights by an American carrier into Heathrow.

And 250/7 is just shy of 36 flights per day. Not 50. 7 daily slots times 7 days is 49....or about 50 weekly slots or 1 gate.
