The improved Suppressed Demand tooltip and info badge.

Changes

  • Manufacturers are now much more responsive about opening new production lines when their backlog grows.

  • New lines are triggered by how many days of work are queued instead of raw plane count. This should help esp. with slower-to-build planes like the PAX series.

  • New lines also go to the model with the longest queue in days of work instead of the most planes.

  • Overhauled the Suppressed Demand badge. See the screenshot!

  • AI airlines are now much less aggressive about opening new routes if their existing network is struggling.

  • AI stops opening new routes while more than 10% of its routes are congested.

  • The airport Congestion tooltip now shows whose fault it is. Maybe it's your competitor's preferred queue!

Bugfixes

  • Fixed passengers who prefer an airline that doesn't fly their route waiting instead of just boarding a competitor.

  • Fixed demand suppression kicking in way too early.

  • Fixed passenger groups losing their place in line when only part of the group fit on a plane.

  • Fixed partially-boarded passengers sometimes jumping from the open queue into some preferred queue.

  • Fixed passengers who were split across two planes losing their demographic and airline preference.

  • Fixed AI airlines ordering planes past their own per-model fleet targets.

  • Fixed AI airlines attempting to open new routes and construct buildings way too frequently.

  • Fixed the Tourist Destination demand boost silently deleting itself after saving and loading.

  • Fixed a multiplayer bug.

  • Fixed some minor text issues.
