Fly the Line is the ultimate career-driven experience for flight simulator enthusiasts, now arriving in your favourite sim platforms!
Take your place in the cockpit as a short-haul airline pilot and begin your journey from Junior First Officer to Fleet Captain. With every flight you’ll build your aviation legacy - navigating realistic schedules, managing tight turn-arounds and handling unexpected diversions, all while flying the aircraft of your choice.
As you complete flights, you’ll earn cash, XP and skill points that can be used to unlock new abilities, improve your lifestyle and enhance your well-being. These elements don’t just add depth - they directly impact your performance and progression, making every decision matter.
Getting started is simple. Choose your airline, select your home base, generate your route network and you’re ready to fly.

Adds purpose and progression to flight sim specifically aimed at short-haul operations.
This addon is the ONLY addon i go to anymore for flight schedule simulation. There was some flaws with it when it was just the "Short Haul Edition". But on August 4, 2026 they released a new version called "Fly The Line: Airline Edition" which is now out on Just Flight but has not been updated here on simmarket as simmarket is slow at updating it apparently. If you own the Short Haul Edition then you get the Airline Edition free!
If you check out what the Airline Edition offers it basically fills all the wishlist items from me and I'm sure other users of the software.
It now allows custom route making for custom airlines, etc. It also allows "long haul" flights!
It has just gotten a much needed update to allow new items, if you wish to check the updated items, please check their page on Just Flight.
The only thing I still wish they would allow is cargo ops, but they may allow it with the new update, as i don't know yet.
I’ve been using Fly The Line for about **38 in-game days now
All airlines I actually want to fly are available. Great for immersion if you like to replicate real airline operations.
Virtual airlines are also possible. One thing to be aware of though: when creating routes for virtual airlines, you should filter airports quite aggressively. The route calculator can eat a lot of RAM, and if you leave too many airports in the search pool it may even crash.
The after-flight analysis is one of the highlights of the app. It’s very detailed and gives you a rating plus XP points after each flight. Watching your performance and slowly improving is quite satisfying.
Touchdown zone scoring is extremely strict. To get the full 5 points you must land exactly within 50% of the TDZ. If you're even 1% short of that, you only get 3 points.
Another thing that works really well is the career progression system. Getting promoted through ranks and receiving salary increases is surprisingly motivating.
A big part of the app is also the life simulation running alongside your pilot career. You have to furnish your house and manage things like health, exhaustion, mood, etc.*during your off time. It adds a layer of role-playing.
Things I don’t like that much:
The landing analysis doesn’t include a statistic for centerline deviation/tracking.
Touchdown zone scoring feels overly strict.
Odd design decision that you start without basic bathroom equipment (toilet and sink) in your house.
Calendar system loops the months. I started in February, flew for a full in-game month, and then the calendar returned to February 1st again. The only way to move to the next month is by creating a new route, which breaks immersion a bit.
Suggestions and Wishes
One idea would be an option where you cannot immediately fly any aircraft type. Instead, you would first need to complete a virtual type rating before being allowed to operate that aircraft.
I would also love more depth in the procedure evaluation, checking for things like:
* Beacon before engine start
* Landing lights used correctly below 10,000 ft
* Centerline deviation during takeoff and landing
Another improvement could be the Airline job system. Right now you can switch airlines anytime, but it would be more immersive if you had to **ply for a new airline and be evaluated based on both flying skills and pilot condition (health, fatigue, etc.)**.
Active Sky integration would be fantastic. For example, the training captain could reference the weather briefing from Active Sky before the flight.

Summary:
Despite a few quirks, Fly The Line is a *ery engaging career companion for flight simulation. The combination of detailed flight analysis, career progression, and life simulation gives every flight a sense of purpose.
After 38 in-game days I’m still motivated to keep flying.
To be perfectly honest, I don't recommend buying this add-on. In fact, I deeply regret buying it. It works great in the advertisements, but in practice it's terrible. It doesn't recognize all airline ICAO codes, and because of that, I couldn't even use it, since career mode doesn't interest me. When creating a fictional airline, too many airports appear, and it simply freezes trying to create routes. I'll stop using it and wait for a future update to fix the negative points.
