That is because they do not fly a lot and have maintenance by the hour.
In this game maintenance is the same as it is based not on flying time but real time.
Maintenance on older planes will kill you!

Zantop International flew very well maintained L-188 Electra's and DC-8's up until the early 2000's. They flew contracted routes for other lines as supplementals, and was the go-to airline for the American Automotive Industry, flying parts all over the place to keep the assembly lines going. They were known for the outstanding maint. program they had for these aircraft, and trained others using them.

In the end, it wasn't the old aircraft that did them in, but Pilot's Union troubles.

Don't forget all the DHL cargo flown by the likes of Atlas, Southern, Kalitta, and ABX. And the numerous small feed runs that are still flown by 9-30 seat aircraft that are 35+ years old in the USA.

Of course Order Aircraft fly (or have flown) freight today. But their utilisation is low (DHL aircraft sit idle during the day to fly a quick return in the evening and back before morning)
The maintenance cost is a function of the (low) number of hours flown.

In AWS the maintenance costs (and pilots) are the same whether you fly your aircraft 1 or 12 hours. Hence the benefit of flying as full a schedule as possible and the heavy maintien even burden of flying older aircraft. (Maintenance costs increase exponentially with aircraft age)

Even if you can fly older aircraft my point about it being too costly (given AWS calculation methods) remains
Swiss quality all over the world

Tying maintenance costs to flight hours and cycles would solve this issue. And also allow for airlines using a different business model such as Allegiant; buy a well maintained old MD-80 for $4 million, and fly it once or twice a day. Scrap it when the next heavy mx comes up. Could be a great opportunity to implement this together with city based demand and cargo.

Hello!

I want to add something new to this topic.

I think that full-cargo airlines should be allowed to open bases anywhere in the world. There should not be any restrications, such those in current games (opening bases only in HQ's country/UE). Most of the cargo airlines have bases throughout the world. FedEX and UPS operate at literally every continent, Cargolux operates base in Zhengzhou, China and even Lufthansa Cargo has bases in Russia and India.

What do you think about it? :)

They may operate a "Base" there, but almost always in conjunction with a locally-owned operator.

For Instance, DHL operated in CONUS for a decade, but only by operating a completely different company and airline with US Majority Ownership. The same rule applies almost everywhere.

The Fedx and UPS International "Hubs" aren't really hubs, but fed from local operators.

So IMHO use what the RW currently uses, which is LD3s and LD6s.

Very simple, larger aircraft, 757, 767, A330, etc carry the LD3's and LD6's.
https://en.wikipedia.org/wiki/Unit_load_device
That wikipage has the basic info on the LD3 and LD6 plus what each cargo aircraft can hold.
And for sake of simplicity use the same size dimensions for smaller aircraft, 737, A320, E170, etc. And sense an LD6 is just 2 LD3s it would be very easy just to use LD3s. It is the universal cargo shipping method in the airline industry, at least for the past 30 years.

The cargo system has already been made and is currently in the test phase. A system of volume vs. payload is used and three classes of cargo can be transported (light, standard, heavy)

Any updates on when this is to be implemented in a full world?

Would be nice as a mini game and as it is still under construction you can disable the achevements for see how it goes.
Looking forward to fly Cargo together with pax and see.
So if there will be a test game then sign me in :)

The basic problem with freight is that we have two variables,

 * volume (cubic meters/feet)
 * weight


In real life we can send a package that is 10 m3 in volume, but it can weigh from 0,5 kg to 5000 kg depending what it is. This naturally makes all the difference on to what kind of plane it can be loaded; dimensions and payload capability are the factors. And the COST of the freight is also dependant on this - airlines take the higher of the costs and charge that. If it's a light but large package, they make you pay according to the size, and vice-versa.

For the purposes of AWS we know the available volume of freight holds for aircraft, and we also know how much weight it can transport to certain distance (with full passenger load).

The tricky part is to combine the volume&weight variables into single factor that would be the "freight demand", for example "30 m3 of freight from XYZ to ZYX".

But to think of this idea further we could split freight into several categories (considered them travel classes, like C & Y & F) like suggested. But there is still a need to make a unified value (consider it an average) on what a certain volume of freight weighs (needed for payload/range stuff). For example: Light freight weighs 1 kg per 1m3, medium freight 100 kg per 1m3 and heavy freight 1000 kg per m3?

Package dimensions can't be considered as that would be complicated combined with the other stuff. But perhaps that can be simulated so that heavy freight requires a large or very large aircraft, and medium freight a medium plane, and light freight can be transported with any plane?  And 'superheavy' (ie. AN-124) freight is charter type stuff, so that won't be included.
One thing can be done is to assume standard volume-to-weight ratio like the other game, as airlines would usually balance those light-but-large cargo with those small-but-heavy cargo, unless you want to make some destination more likely to get high density cargo while others get low density cargo.
