After nearly 2 years I've "rediscovered" your website and have tried my hand recently at new BW scenario.
I like the improved interface very much. I appreciated also the information that new features have been added (e.g. alliances) though not available in BW/Demo scenarios for obvious reasons
Here are my thoughts regarding any potential/further improvements:
(sorry in advance if my ideas stem from my still not very profound knowledge of the game)
1. C - checks:
Whereas A/B-checks can easily be dealt with by arranging the weekly schedule accordingly the case becomes more complicated with C-checks...
The bigger airline you have the bigger problem it creates. So many C checks require almost 24/day attention (aircraft swaps) Frankly it was the reason of my second bankruptcy since I went to the mountains for a few days off and could not see to it as often as needed
Do you consider implementing some kind of a tool which would actually help to organize the process automatically (for instance by providing the fleet with an extra number of disposable aircraft?)
2. Loyalty (frequent flyer) Programmes
Introducing an FFP would add verisimilitude to the whole concept of marketing - it does remain a very strong marketing tool generating up to 30% (or more) of real-life airlines' revenue. Even after reaching route image of 100% it can still be a deciding factor within a very strong price competition.
3. Aircraft types images:
As I remember well they did not change much since last 2 years.. it's high time someone refreshed it a bit
(I'm sure both Boeing and Airbus as well as other makers would allow using their nice looking factory-livery images)
Last but not least
4. When a given scenario is already in the final stage (closed to new players) maybe it's time to open a new one. Some wait impatiently to join the game
Thank you Sami for having created this fantastic simulation! It's a real fun!
