You are nobody with a plane. Your aunt staked you a little seed money. The industry has carriers that have never heard of you. The only aircraft you can afford is a leased eleven-seat turboprop. Everything you will ever own, you will have earned: the first profitable week, the first plane with your registration on it, the first jet, the first time a rival you used to look up at appears below you on the ladder. Skyline Sim is an airline management game built like a flight deck. Dark instruments, live numbers, decisions with weight. ROUTES Real cities on a real satellite map, with your network drawn between them. Weekly demand tells you who wants to fly and where nobody flies them direct. Every route is a boarding pass with load factor, on-time performance and weekly profit. Set the fare, set the frequency, watch the pass fill. FLEET Lease on day one, buy used when you can, order new when you have earned it. Fifteen airframes across turboprops, regional jets, mainline jets and widebodies, unlocked tier by tier as your market cap grows. Each aircraft carries three dials for wear, condition and range. Configure the cabin seat by seat. LIVERY Pick a paint scheme and a fin emblem. It goes on every aircraft the day it joins the fleet, tail, cheatline and all. PEOPLE Pilots, cabin crew, and ground and maintenance, each with happiness and workload meters, a wage you set, and job ads you post. Overwork shows before it bites. Fill the executive desk with a Head of Operations, Maintenance, People and Finance, and unlock a research tree of twenty-three upgrades. MONEY This is where you find out whether the quarter worked. Revenue and profit draw as traces on a black display. Unit cost as RASK against CASK. Break-even load factor for every route. A quarter report grades you, and a bank and investors watch how you do. THE INDUSTRY Sixty-eight carriers on a ladder, real rivals with real names, suppliers you bargain with, fuel prices that move, and a deck of events that can hand you a windfall or a cyclone warning. Crashes, courts and recalls arrive when you are big enough to be worth suing. FOUR HOME COUNTRIES The United States is the premium game: rich fliers, expensive union crews. India is the volume game. China is the patience game. Australia is the optimisation game of long thin routes. HOW IT PLAYS Time only passes while you are playing. Nothing happens behind your back. A session is a few weeks of the sim; a campaign runs from survival to empire. Free, with one optional sponsor ad you can choose to watch for an in-game bonus, and one short interstitial at most per quarter. No purchases, no accounts, no sign-in. Three save slots, all on your device. Plays fully offline. Built for iPhone. Requires iOS 18.

Verdict
The clearest difference is price: Skyline Sim at Free against REI Empire's $4.99. Skyline Sim also leads on update cadence (fortnightly vs every 3 months). REI Empire's advantage is ads (none vs shown) and device support (3 vs 1). On in-app purchases there is nothing between them.
