About the Game
Fly from Tokyo to LA, the short way.
Build your dream airline network on a custom-made globe of the Earth as you listen along to the game's original music. Or if you want, you can even play on terraformed Mars!
Compete with other airlines.
Advertise, construct hotels or steal concourses at airports to gain the upper hand against your competitors. Then, kick them out of your hub airports or purchase them outright in a hostile takeover.
Hub-and-spoke or point-to-point?
You decide. You can centralize your network to build a hub or utilize the game's flexibility to send your planes on long multi-city cycles.
Airports are ever-evolving.
At the start of the game they can spawn with random bonuses, and as the game continues you must make decisions such as building hubs, lounges and more in order to optimize your network.
Choose your flyer.
Play as the luxurious Flamingo, which receives bonus income from all lounges. Soar further than others with the Eagle, who gets a boost to plane range. Play as the Crow, Gull, Ostrich or more...all with their own unique bonuses.
Play with your friends.
Invite or join your friends through Steam and build a global airline network together.

Notes
Modding guide not released yet, some undocumented features include overriding existing planes. You can set "Enabled": false to take a plane out of the game entirely if e.g. you don't like the Roebling becauses it's too fast.
{ "Id": "puffin.roebling", "Enabled": false }
In general, you should be able to easily override fields like this:
{ "Id": "puffin.pico", "Cost": 12000, "Capacity": 90 }
v20.2-pre1
This is a preview patch, so you must be on the PREVIEW branch to try it.
Changes
- Congestion is now measured only against the queue capacity of airlines who actually operate at the airport.
- Since congestion drives demand suppression, expect stronger suppression at hubs now. This will change how the game plays, so feedback appreciated here.
- Since congestion drives demand suppression, expect stronger suppression at hubs now. This will change how the game plays, so feedback appreciated here.
- The Congestion tooltip now shows each queue's fill against its own capacity (for example 208/204, overflowing) instead of its share of all queued passengers.
- Renamed "Throughput usage" to "Boarding throughput" to clarify that it specifically measures how fast that passengers who are already at an airport can board their planes.
- Improved changelog
Experimental
- Experimental mod support (proof of concept, may break in future updates). You can drop JSON files into the Mods folder next to your saves to add custom airports and plane models to new games.

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.
v19.3
Bugfixes:
- Fixed bug where players would be unable to join a multiplayer game if the savefile was big.
- Fixed bug where airlines would not get money if they were forced to sell shares.
- Fixed bug where bulk order button would become clickable before you could actually afford it.
- Clicking on an airline's avatar in the route GUI will now navigate to that airline's stock trading view.
- Aircraft will now show 'Repairing' if they are repairing, to better inform players that they may need to build more hangars.
- Stale events will no longer show on game load.
Bugfixes:
- Fixed bug where AI would sometimes try to buy shares in dead airlines.
- Fixed bug where there were some blank tooltips in the stock trading view.
v19.1
Bugfixes:
- Fixed bugs with tutorial
- Moved the 'accept contract' button so that it is no longer hidden by the tutorial.
v18.1
Features:
- Added a "Random starting location" option in the New Game menu.
Bugfixes:
- "Veteran Veteran" achievement now takes into account used plane purchases.
Hello everyone, I'm back with a dev diary for Puffin Planes. I'll start posting occasional dev diaries instead of posting every single preview update as an announcement; this will help keep the library view cleaner. I'll still try to post patch notes to Steam and Discord though. By the way, did I mention that the game's on sale? Actually, I don't know why I'm mentioning this. If you are reading this dev diary then you probably already own the game. Maybe you can buy it for a friend? Anyways...
Coming Soon in v17.1
(And currently available on the preview branch)
New Main Menu
In order to redo the main menu windows, I first needed to reconfigure the main menu so that there was more space for them. To accomplish this I moved the action buttons over to the side.

Airline customization
You may have spotted in the previous picture a new "Airlines" tab in the New Game menu. This lets you customize the airline! You can now customize a few additional settings such as the bird and the start location.
[img src="{STEAM_CLAN_IMAGE}/45002107/bd2f0d5d9b40cb3cf507bb79dc44df9fe6d41d90.png"]
Advanced game rule customization
I added many more game rules for you all to customize. I know I can't satisfy everyone's preference for how they want to play the game, so I thought I would at least give everyone more choice.
[img src="{STEAM_CLAN_IMAGE}/45002107/d766df5de7441ecf78e02bd99619f761217af844.png"]
Loans and your CRANE Score
You heard that right: loans! These are definitely not balanced yet, I'm afraid. In fact the whole v17.1 update is probably unbalanced as heck right now. But hopefully, armed with the new game rule customization options, I can get some feedback from playtesters on the appropriate balance this new mechanic.

Full v17.1-pre4 Patch Notes
Features:
- New "Expand Airport" button on the Infrastructure GUI panel that allows you to add another building slot.
- Your airline now has a CRANE rating. This will affect how eager lenders are to give you money.
- There are four new loans available for you to take out.
- Whenever manufacturers launch a new model/block, they will offer discounts to each airline on their first 5 or 10 orders.
- Tons of new game settings including over features like buyouts, plane maintenance speed, and so much more.
- Can now customize individual airlines before game start.
Changes:
- Bulk discount has been reduced from 20% to 15% of the plane cost.
- Increased fuel efficiency of the Atto from 0.85 to 0.95
- Reduced upkeep miles cost from 8/health to 7/health
- Inflation is now ~25% of what it used to be. The old "Normal" inflation is now the new "High", for comparison. The idea is to try and increase plane costs and add early-game loans rather than rely on inflation for a more engaging early-mid game.
- Rebalanced plane costs; smaller planes increased around ~2x, larger planes between ~3-5x.
- Production line base capacity has been nerfed from 8/hr to 6/hr; I felt planes were being built too quickly. But starting efficiency has been boosted to 100% to compensate at least at the immediate start of the game.
- AI will now be more aggressive in stockpiling planes.
- Moderately decreased the cost for manufacturers to open new production lines.
Bugfixes:
- Fixed the Comfort chart.

- Debug menu will now show you airports that you have never unlocked before, for help with the Completionist achievement.
- If a new model is researched and there are no production lines to steal, then the manufacturer will go into debt to open a new one.
- Moderate (25%-ish) decrease to the price of starter planes
- Tightened up research costs to make planes appear earlier on average.
- Plane labor unit cost increases again (sorry I keep going back and forth on this).
- Two new planes, the 'Levering Veteran ER' and the 'Sawtelle Macro'.
- Added some more flavor to production line names.
- Nerfs to % income policies such as the "Status Program" and "Low Cost Carrier" policies (now just a 2.5% boost across the board except for LCC)
- Nerfed the Puffin % income bonus from 15% to 10%
- Significantly increased crew costs (50% increase); aiming for plane operating costs to be around ~80% of revenue
- ...to compensate, base income is back! Should help you out early game; 500 per day.
Bugfixes:
- Route ruler now shows the stats for the highest block that you have.
- Fixed the Midvale PAX-250 research cost being absurdly low for testing purposes.
- Fixed a typo in teh "Establish a Hub" contract.
- Removed references to the abandoned "lease" concept from the game.

- Made some pitiful attempts at game balancing (I swear it's so difficult!)
- Raised the amount of starting miles from 25K to 30K
- Significantly increased most plane prices (by 2-3x for many of them)
- Production lines should now slowly reassign to models with busier backlogs (threshold is 2x total length in days)
Bugfixes:
- Fixed airplane costs (fuel, crew, etc) not scaling with inflation (mega facepalm)
- Fixed discontinued planes getting new production lines (e.g. PAX-125)
Changes:
- AI is now less aggressive about ordering+stockpiling planes (unless they have the Hoarder trait)

- Fixed bug where when a new model became available, the manufacturer would panic when trying to find a production line for it.
v17-pre9
Changes:
- The "production line" concept has been partially split off into the "orders" concept.
- You can now only order the latest block of a given plane.
- Older blocks will be "retired" after all outstanding orders have been completed.
- Manufacturers will prioritize finishing outstanding orders for older blocks before moving on to newer ones.
{STEAM_CLAN_IMAGE}/45002107/bb6a883958be2b1144d185e42978602733b8fe41.png
- Removed the priority queue, replacing it with a new 'Priority Deal' mechanic. Priority Deals are first-come-first-serve and result in any existing orders being moved up in the queue rather than being put into a separate queue.
