Hi,
I am obviously i am working on adding historic airlines of europe into the game, but one issue i would like clarification on are IATA and ICAO codes.

Any airline between 1930 and 1947 will not have an ICAO code as they weren't introduced until 1947 and any airlines between 1930 and the early 1950's won't have an IATA code as they weren't introduced until 1953 (ish).

So most airlines i have put there successor codes on but some airlines like Air France have 5-10 predecessors, so what should i do about that?

I feel some sort of Route Distance Calculator is neccesary.

I am forever getting slots for routes that are too far away to be operated and only finding out they are too far away after i have reserved slots and paid for them, then the long winded process off cancelling those slots so i end up giving up and just having slots at airports i can't ue.

Hello everybody,

I'm just wondering what the airport landing fees are based upon in the game. Is it aircraft weight? Passengers inside? Something else maybe? I am not sure, but if someone could tell me that would be great.

Thanks.

The game worked very well  from 1930 to 1971... but  it froze in 1971.  When I tried to save game crashed.

on my research on Tuvalu, I found these stamps, what shocked me was that it said "Internal Air Service" after deeper investigation, i found out the service DID exist (Until 1993,mainly because of G73 Mallard's Aging) 

and then Tokelau came along...
i found out they also had a Domestic Air Service operated by Air New Zealand (Until 1983 this time, 'cause the Mallards won't stop aging) 
also,there was a plan to build a runway in Faka'ofo but it didn't go ahead. Alternate Scenario? Who Knows...
seemingly both served the whole place so,that'll be 10 harbors:
Tuvalu:
Nui
Vaitapu
Nukulaelae
Niutao
Nanumea
Niulakita
Nanumanga
Tokelau:
Atafu
Faka'ofo

Crash when I was changing the seat config of a Fokker 28 (added 4 rows of business class seats, 16 chairs) and it crashes when clicking 'Ok'. Reproduced multiple types with different models of the F28.

Crash log included as attachment, looks like it's trying to reference something that hasn't been instantiated yet. Best of luck!

Hello
Funny thing has just occured to me a moment ago, it is the beginning of Semptember 1965 in-game. I got the mail that runway had been closed at Madrid-Barajas. I checked things out and it appeared that my two airliners at this destination were gone from the fleet list. The route also vinished from all listings, but destination with empty slots remains.
Surely there are some sinister forces behind this, UFO perhaps . But maybe they reappear on some remote desert in the future .

As you know, I have started the Airlines of Europe Project, but i have a question.

How would you code in an Airlines information to see it merger to form another Airline?

For Example:
Air Orient, Society Generale des Transportd Aeriens, Air Union, CFRNA and Compagnie Generale Aeropostale all mergered together in 1933 to Creat Air France.

Not sure whats causing it?
