Good day,

In Patch H, I try to create a new airline. I click on the '+ CUSTOM AIRLINE' button. In the popup window, I choose a start date, like 1987

At this point, the game hangs up and I get a windows popup that says the program stopped responding. During a few attempts I thought it had crashed, but it turns out you have to wait for the program to respond. I actually only found this last part out while typing this bug report.

I figured you might like to know this, so you can either avoid the hangup, or add a warning to be patient. Otherwise you might get users thinking it's a bug.

Hope I've been of help, thank you for making this lovely game!

It would be really cool if we could create new fare classes, like many airlines have IRL - where you can pay extra and receive a full meal, a checked bag, priority service, free wifi, or other perks, without actually upgrading to new seats. Being able to target more than two or three segments of the market, and provide a way to squeeze as much money as people are willing to pay, would add some interesting gameplay. It would potentially add some roleplay potential too, as it mirrors real-life trends.

Game ran fine for 5 yrs. Sudden stop at season change, no ctd, nothing written in log

Hi,

My compagny was notified by mail in 01/02/1942 that C54-Skymaster "is now avaible for purchase".
But this plane does'nt appear in the list of Douglas Aircraft Compagny when I look for it in order to buy.

The others aircrafts notified " now avaible" at the same date, as the L-049 Constellation, are listed, and really avaible for purchase.

I'm playing an customised compagny, founded in Altanta USA, focused passenger, I chose the option "ignore the wars", version 2.14Patch H.
I tried, creating an subsidiary focused Cargo, to buy a C-54... same thing.
The same bug appears in the previous patch.

Hello, I'm new to this game, but I really like it.

I've tried to find the answer for a few days, but I just could not find any. So the question is: Is there a way to create a stopover route?
When I go to the Routes > Create a route - I don't see any tool for stopover flight. Or am I just blind? (It happens sometimes  )
I have my own custom airline operating from Wien, and the early Jets in the 60's just dont have enough range to reach for example USA.
I'd like to create a route, for example: VIE - LHR - ORD.

Thanks for help! 

i open the game .exe,and wait 30min and guess what,it didn't start,like,not even a window.
log adds this: "10/10/2019: 22:08 System.TypeInitializationException: The type initializer for 'TheAirlineProjectV2.Infrastructure.Model.CollectionsModel.CachedCollection`1' threw an exception. ---> System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.Configuration.ConfigurationErrorsException: Unrecognized configuration section startup. (C:\Users\usuario\Documents\TAPv2.14\TheAirlineProjectV2.exe.Config line 7)"
please help

Everytime I want to change my planes seat configuration, the game crashed by the time I clicked the OK button.
Custom Airline, 2019 start, all type airlines, no major airports and airlines unchecked.

Once the AI is better how about these:
You could have an Alliance of airlines that interline with each other and when you build a terminal you could choose to have it as an individual airlines terminal or an Alliances Temrinal?
