Development Roadmap

Geopolitical events make certain routes illegal or require re-certification. The Cold War blocks Moscow to New York until détente. Indian independence reshapes colonial routes. The USSR dissolution opens 12 new republics while making Soviet domestic routes obsolete. Forces adaptive rerouting each era.

Major airports implement periodic runway closures or gate curfews tied to weather or maintenance: Denver in winter, Heathrow night curfews, Tokyo during monsoon season. Forces rerouting or temporary suspension.

Quarterly safety audits: poorly maintained fleets face regional demand penalties until they pass re-inspection. Rivals are subject to the same rules. A competitor neglecting maintenance will feel it.

Regional economic integration creates demand bonuses for connecting key city pairs. Corridors break during trade wars or embargoes, and rivals compete to claim the same routes.

Real-world aircraft retirements (Concorde 2003, DC-10 decommissioning) force players to proactively replace aging fleets before demand collapses. Creates strategic urgency around succession planning.

43 major hubs follow hand-tuned historical growth curves (Heathrow 1946, Changi 1981, Incheon 2001). All other airports grow dynamically by city population and aviation era. New Airport Expansion Alerts fire each January.

After winning an era, earn Legacy Points based on your domination metrics. Spend them on permanent unlocks: starting aircraft, lower slot costs, faster capital accumulation, or cosmetic airline badges that carry over to future runs.

Hand-crafted scenarios with unique goals and starting conditions: the Berlin Airlift supply race, breaking Pan-Am's trans-Atlantic monopoly, rebuilding from near-bankruptcy in the post-WWII era, and more. Includes scenario progress tracking across runs.

After winning an era, choose your legacy: Consolidation (40 bonus years building mega-hubs) or Fall from Grace (rivals merge into a single mega-competitor and you must survive). Each epilogue has unique victory conditions.

Routes track long-term demand history. Recession events compress demand globally, and players can pivot to more stable cargo operations or ride out the downturn, creating meaningful economic decisions across time.

Negotiate peak-season permits for routes that only make sense part of the year: summer tourism, winter ski resorts, or the Hajj pilgrimage. Temporary permits cost less but require quarterly decisions.

FIFA World Cups, Summer and Winter Olympics, World Expos, UEFA Championships, Rugby World Cups, Cricket World Cups. 8 recurring historical mega-events boost city demand in host regions and reshape competitive pricing around major dates.

Full hub-and-spoke algorithm with transfer UI, AI transfer awareness, and a Casey hub tip system. Routes can now act as feeders into major hubs, creating emergent network strategies.

Every screen in the game now has proper controller focus navigation (d-pad, focus rings, and focus lock on overlays) so the full game is playable with zero keyboard or mouse.

Origin selection persistence, win progress HUD indicator, trackpad zoom fix, Strategic Advisor "BUY ALL" fix, demo expiration handling, and dozens of smaller UX refinements.

Worst Routes Panel, Aircraft Timeline, Performance Benchmark, Keybinding Manager, Epic Games Bridge, Accessibility TTS, and the BusyIndicator system. All quietly shipped to improve the overall experience.

Your airline's stock price reflects revenue, reputation, and market share. Pay dividends to boost investor confidence, or reinvest for expansion. Rivals have stock prices too, and takeover attempts become possible when valuations drop.

When a rival tries to acquire your airline, deploy defensive strategies: poison pills, white knight partners, stock buybacks, or shareholder voting campaigns. The existing acquisitions system becomes bidirectional.

Manufacturers run production queues. New aircraft take 1 to 6 months to build. A global backlog tab tracks every order on the way, with a cancellation fee if you change your mind. Frame the order early or watch rivals beat you to the gate.

A dynamic AAA-to-D credit rating based on debt-to-revenue, cash reserves, and operating consistency. Your rating determines loan interest rates and whether banks will lend to you at all during downturns.

Post-2005 carbon markets. Older fleets cost more to operate under EU ETS; modern composite aircraft save emissions. Trade quotas with rivals on an open market. Aligns with the existing Carbon Offsets diversification.

Run ad campaigns in each city you serve. Tiers from $100K to $1M lift your local brand score. Every brand point adds passengers to routes touching that city, and a Chief Marketing Officer pushes the whole effort 50% further. Buy your way into a market without buying a single new gate.

Quieter aircraft unlock restricted airports (Washington National, London City). Operating loud 707s at sensitive airports costs reputation and triggers community complaints.

Historical "open skies" agreements unlock route pairs. Before 1978 US deregulation, most international routes required bilateral permission. Creates natural chokepoints and strategic inflection moments.

Configure each aircraft route with First/Business/Economy/Basic Economy mix. High-business-class routes unlock premium demand pools; all-economy configurations maximize capacity on leisure routes.

Negotiate codeshare agreements with rivals for routes you don't fly. Revenue splits, alliance formation, and the strategic choice between competition and cooperation.

Invest in research to unlock aircraft upgrades (winglets, fuel efficiency packages), ground systems (faster turnaround), or IT (yield management, loyalty programs). Creates a parallel progression vector.

Declare yourself a full-service carrier, low-cost carrier, ultra-long-haul specialist, or regional feeder. Each identity has unique buffs and debuffs, forcing commitment to a strategic archetype.

Sandbox mode toggle to enforce the full ICAO "Freedoms of the Air" hierarchy: cabotage rules, fifth freedom rights, and seventh freedom operations. For simulation purists.
