inFlight: the add-on that finally gives the empty cabin behind you a voice

There is a particular silence in Microsoft Flight Simulator that you stop noticing until something fixes it. You push back from the gate, run the flows, rotate, and behind the cockpit door there is nothing. No boarding chatter, no cabin crew, no seatbelt chime. Two hundred people are theoretically sitting back there and not one of them makes a sound.

A lot of add-ons have gone after that silence. Most of them are soundboards — you get a panel of buttons and you press Welcome Aboard somewhere around the top of climb, and it works, and it also means you are now a flight attendant as well as a pilot. inFlight, from Double5 Media, takes a different route: it watches your flight and fires the right audio on its own, then keeps going into territory the soundboards never touch — an economy, aircraft ownership, and a grade at the end of every flight.

That is the interesting part. The frustrating part is how little independent evidence there is to weigh it against, and that shapes everything below.

What you are actually buying

This is the first thing to untangle, because the product has been sold under more than one name and the pricing has layers.

Where	What it is called	Price
Steam	inFlight Addon for MSFS	$39.99
simMarket	inFlight Console — PAX/Crew Sounds/Scoring	€29.99
inflightaddon.com	Standard, one-time	Lifetime ownership
inflightaddon.com	Premium, subscription	$9/month or $99/year

There is also a free basic tier and a three-day Premium trial. The simMarket listing dates to November 2024; the Steam release is much more recent, 27 March 2026. Same lineage, different shelves.

Standard is a one-time purchase you keep. Premium adds the AI-generated voices and the real-time data features, and if you cancel it you drop back to Standard rather than losing the app. That is a more honest subscription than most — you are renting the AI voice generation and the live data feeds, which genuinely do cost the developer money on an ongoing basis, not renting access to software you already bought.

It runs as a companion application beside the sim rather than as a package inside it. That means a few prerequisites worth knowing before you buy: a free inFlight account, the .NET Desktop Runtime 6.0.22 (x64), and an active internet connection. Minimum spec is undemanding — an i5-8400 or Ryzen 5 2600, 4 GB RAM, 500 MB of disk — and it works on both MSFS 2020 and 2024.

There is a seven-day money-back guarantee with an unusual condition attached: you have to have completed at least three full flights. Read cynically that is a hurdle. Read the other way it is a developer saying actually use it before you decide, which for an add-on whose whole value shows up over the length of a flight is a fair ask.

What the community consistently praises

Here I have to be straight with you, because this section normally does the heaviest lifting on this site and it cannot this time.

There is no community consensus on inFlight yet. The Steam page carries no user reviews at all. AVSIM and the official MSFS forums have threads about cabin announcement tools that discuss Universal Announcer and CabinSim without mentioning inFlight. What exists is one piece of independent coverage, a handful of vendor-published testimonials, and the developer's own material. Everything below is drawn from that thin record and labelled accordingly.

The one independent write-up, from MSFS Addons in February 2025, was cautiously positive. It picked out the compact UI mode as a less intrusive overlay, the automatic aircraft detection, and improved responsiveness in the interface, describing the interaction as streamlined and efficient. It stopped short of a full endorsement, for reasons covered in the next section.

The testimonials simMarket carries are short and specific in a way that reads as genuine — one buyer saying they cannot stand flying without it now, another noting they no longer need a second program alongside it. A user comment surfaced around the Steam release said the AI speech was clear, installation was easy, and it did not cost them any performance. Vendor-published, so weigh accordingly, but the performance note matches what you would expect from a companion app this light.

What I can assess directly is the design, and the design is the strongest argument for it. The automation is the right call. An announcement system that needs you to trigger it is solving half the problem, because the half that breaks immersion is remembering to be the cabin crew. inFlight reads the flight phase and plays the appropriate audio without input, from boarding through to arrival. The language coverage — over fifty languages and regional variants, including Mandarin, Hindi, Arabic and Russian alongside the usual European set — is unusually deep for this category, and it is the kind of feature that matters enormously to the portion of the community that has quietly put up with everything being American-accented English for fifteen years.

The career layer is more ambitious than the audio, and more unusual. Contractor mode gives you aircraft ownership with real financial consequences, maintenance to keep on top of, and penalties when you crash. Fly Now mode drops all of that if you just want to go flying. Running underneath is a grading system built on NBAA safety guidelines that scores you on handling and flags passenger comfort violations, which is a more interesting basis for a scoring system than the arbitrary point totals these things usually run on. Add SimBrief integration, a live traffic map and real-time airport data, and the pitch that it replaces a flight tracker, a career generator and a sound pack all at once is at least structurally true.

What keeps coming up as a problem

The headline problem is the one MSFS Addons put its finger on, and eighteen months later it has not really been solved: there is very little material showing what inFlight actually does inside the simulator. Their words were that there are very few examples of it in the sim, only a video from the developer. That was February 2025. Searching now, the situation is not much better — the YouTube presence is largely first-party, and independent video coverage is thin to absent.

That matters more for this product than it would for an aircraft. Nobody needs a video to understand what a 737 is. An audio and career layer is almost entirely experiential — the question a buyer has is does this feel right in flight, and that is precisely the question the available material does not answer. The three-day trial exists to close that gap and you should use it, but a trial is a worse discovery mechanism than a five-minute video, because it costs the buyer an install and an evening.

Second: the absence of a review record cuts both ways. No user reviews on Steam months after release is not evidence of a bad product, but it is not nothing either. It means nobody buying today can check the developer's claims against a stranger's experience, which is the normal way people de-risk a $39.99 purchase. "Join thousands of pilots" appears on the site; there is no public evidence available to size that.

Third: the two-product identity is genuinely confusing. inFlight Console on simMarket at €29.99 and inFlight Addon on Steam at $39.99 are close enough to look like the same thing and priced differently enough that a buyer will want to know which they are getting and why. Nothing on the storefronts explains the relationship.

Fourth, and the one I would weigh most heavily if I were deciding: this is a paid product in a category with capable free competition. Universal Announcer and CabinSim are both on flightsim.to at no cost, and CabinSim ships with a large library of genuine announcements from real airlines. Neither automates the way inFlight does and neither has anything resembling the career layer, so this is not a like-for-like comparison — but a buyer will make it anyway, and inFlight has to justify $39.99 against free. The automation and the career mode are the answer to that question. The storefronts do not currently make that argument clearly enough.

Finally, a smaller thing: the internet requirement and account login mean this is not an add-on you can rely on offline, and the AI voices and live data sit behind the subscription. Neither is unreasonable given what they cost to run. Both are worth knowing before you buy rather than after.

Performance and stability

There is not enough public reporting here to say anything with confidence, and I would rather say that than dress up a guess.

What exists is consistent as far as it goes. The one user comment I found on performance said it did not slow the sim down. That tracks with the architecture — a companion app playing audio and reading flight state is not doing work that competes with the simulator for frames, and the 500 MB footprint and modest CPU requirement point the same way. The recommended spec, an i7-9700 or Ryzen 7 3700X with 16 GB, is really a description of a machine that runs MSFS well rather than a demand the add-on is making.

No crash reports, no bug threads, no stability complaints surfaced in the search. On a product with this little coverage, that is genuinely ambiguous — it is what a stable add-on looks like and it is also what an add-on nobody has stress-tested in public looks like. I have scored this section conservatively for that reason, and it is the number most likely to move when there is a real record.

Who should buy it

Airliner pilots who fly full-length routes. This is the core case and it is a strong one. If you fly two-hour sectors in a study-level tube and the silence behind you has been bothering you, inFlight is aimed directly at that and the automation means you are not managing it while you fly. Take the trial and fly one full route with it.

Anyone who wants MSFS 2024's career loop to have more teeth. The Contractor mode — ownership, maintenance, financial risk, a grade at the end — is doing something the built-in career does not, and the NBAA-based scoring is a more serious foundation than most. If that layer appeals, it is the most distinctive thing on offer here.

Simmers who fly in or from a non-English-speaking region. Fifty-plus languages and accents is the standout feature and nothing else in this category comes close. If you have spent years listening to cabin crew who do not sound like any airline you have flown, this is the one to try.

Bush, GA and short-hop pilots — probably not. A Cub does not have a cabin crew. There is audio coverage beyond airliners, but the value proposition here is overwhelmingly about the airline cabin, and if you do not fly one you are paying for a feature set you will not use.

Anyone who wants to hear it before paying — take the trial, and expect to have to. The material available online will not answer your question. Three days is enough for a couple of full flights, which is what it takes to judge this. If you would rather not spend an evening finding out, wait for the coverage to build.

On a strict budget. Try Universal Announcer or CabinSim first. They are free, they will not do the automation or the career layer, and if you find yourself wishing they were smarter about when they fire, that wish is exactly what inFlight sells.

Where it stands today

The design instincts here are good ones. Automating the audio instead of handing the user a soundboard is the correct answer to the problem. Building the scoring on published safety guidance rather than invented criteria is the correct answer to a different one. Fifty languages is a real investment in a part of the community that usually gets an afterthought. And a subscription that degrades to a perpetual licence rather than a dead app is a more customer-friendly structure than most of what is being shipped right now.

What it does not have is a track record you can inspect. Every strong claim above about how it feels in flight comes from the developer or from a testimonial the developer published. That is not an accusation — new products start here, and the one independent reviewer who has looked at it came away positive with a caveat about visibility rather than quality. But it does mean the score below is provisional in a way most of ours are not, and it is going to move once there are forum threads and store reviews to read.

What would change it fastest is not more features. It is footage. A handful of unedited full-flight videos showing the audio firing on its own through a real sector would answer the single criticism that has followed this add-on since early 2025, and would do more for it than any update in the changelog.
