No, according to the terms of service no one but you is allowed to use Microsoft systems under your login. Not your wife, not your children.
I’m not saying this is fair, nor that this is enforceable, just that this is what you agreed to when you entered into the contract with Microsoft. And this is why you can’t pass that airport you downloaded on to someone else.
Terms are simple as explained by @NeoKingRthur above. You bought a non-transferable licence exclusive to YOU to use MSFS and any add-ons you license in perpetuity or until they shut down the service. You don’t own the sim nor any add-on any more than you own an apartment or car you’re renting. You’ve paid for the right to use it personally, nothing else.
Any sharing, selling, lending, or passing on of said account is against MS’ terms of service. End of story. Sharing, selling or in any way transferring the sim is a violation of your both the MSFS and your Microsoft account’s terms of service and is considered illegal in most countries.
I’m honestly surprised this thread has been allowed to exist this long considering it’s encouraging what MS would consider to be illegal activity.
I guess the legality is debatable, but sure, you can sell your account, or give it away. Just give that person your login details. Making sure to remove any credit card information, obviously. People did it on NBA 2K all the time. People would make a build, grind the stat upgrades out, then sell the account information. But, no I doubt there’s any way to actually sell or gift individual add-ons for the reasons mentioned.
The legality isn’t debatable. It’s 100% against the legally binding EULA / TOS that you agree to by paying for or signing up for a license.
That said, people are free to make their own choices. Sure, you can sell it. People sell non-transferable MMO accounts, characters, and other game accounts all the time. Just like people drive drunk, commit robberies, murder, etc all the time despite those acts being illegal (although far more serious, of course). Because they do it doesn’t make the legality debatable. They just choose to disregard the legalities. Those are 2 very different things.
I Tunes? I thought that was over. Didn’t Apple ended it?
Yeah, don’t sell it. You’re not allowed to resale stuff you buy. It’s how bad developers ensure they continue to get sales. If you’re unhappy with something, you’re stuck with it. Them’s the rules.
Not sure the further point of this thread.
OP Asks if he can give/sell his account to someone else
It is answered that no, you cannot as it is against Terms of Service.
What other debate is there to be had?
The issue is the mindset here. You see yourself as having BOUGHT this software and OWN your copy of it. And to be honest, no one really reads the EULA / TOS and most people hold the opinion that they own what they’ve bought, even though that’s incorrect.
But you don’t own it. You rent it. LIke I said in my other post, it’s no different than renting a car or apartment. You can’t turn around and sell that car or apartment to someone else because you’ve paid to rent it.
But again, everyone makes their own decision. It’s not like your country’s national police force are going to be kicking in your door and hauling you off to the big house to share a cell with an overly amorous 300 lb cellmate called Bubba for selling your game account.
It was just a genuine question regarding what happens to your stuff if you pass on or if things happen in your life and you cant play msfs anymore and was just a pure question that came from a serious health scare and a reflection on life and if something did happen to me, would I include msfs and all of my stuff in my will like my house, contents and money in bank or is it one of those things that dissappear into thin air..
These are questions best left to your lawyer/estate planner
That said, how is MS/Asobo gonna know if its actually you signing in or if its your loved ones?
It goes back to the old adage “on the internet, nobody actually knows if you’re a dog or not.”
I’m mostly speaking to these folks trying to twist the ToS or saying “it’s open to interpretation.” MS/Asobo has an army of lawyers to prevent people like us from finding loopholes.
Laws exist to keep honest people honest.
I wasn’t denying the TOS. I was saying it’s possible. I worded my response badly. I’m learning you don’t do that around here. It’s not debatable. It’s against the TOS. If I make a one time payment for a product, I have purchased it, not rented it. That’s just legal mumbo jumbo designed to protect developers financial interests at the cost of consumer satisfaction. If I decide I don’t want it, I’ll sell it. I’m not overly concerned with prohibitive small print.
That said, yeah, I think the question’s been answered. Everyone was just giving the by the book answer. I was just letting the op know it’s possible, but not 100% kosher. I apologize if I mis-spoke or mis-led.
There once was a girl / woman at SONY who thought it might be a good idea to say the following (do not remember the exact wording):
“Well, we would like to have the customer buy a CD for his living room, his kitchen, his children’s room and his car as well.”
She said that shortly after the “HIM - Razorblade Romace” Album was released in 2005.
The not so big problem with this album was, that it was nowhere written on the box that the CD will NOT play on any CD-ROM device.
The bigger (and I mean Jupiter-big) problem was that it installed a rootkit on the PC!
The girl mentioned in the first sentence was fired a few weeks later, FYI.
I have absolutely no idea what you want to tell me with that story …
Are you kidding me, I’m taking mine to the next world, i.e. buried with it. I also want the FSX theme music played at my funeral.
That one is absolute gold mate!!! And the walk out theme tune, the current msfs one??
Or…

The way I understand it, buying software is not like buying a bicycle or something.
All you are buying is the right right for you to use the software and nothing else.
Getting it on a CD just makes it easier to get around the limitations but it’s technically still the same so buying it on a disk when available is probably the way to go
This has definitely been also a nostalgia trip reading about thise good old days when a mate gets a cd.. and the other mate gets a cd… then you all have them all when you burn them…
Or…
Recording songs off the radio on cassette and being annoyed that the DJs speak through the intro
Or..
The good old fashioned cd crack codes for Need for speed II SE…
This digital world is definitely a weird one, especially when you deluge deep into what I was wondering about…
Just what happens to your collection should you pass on and legal side of things…
Its literally like, so to, does your digital games collections… it gets the old digital coffin as well so it seems…
There must be a way that you can put in a will or something that your loved ones get your email accounts and they message all your third-party providers and say… "so and so has passed on and is it okay if we/one of us(guessing because its a one person thing) take over their account/he or she left it in the will for his/her favorite child 
Surly there will be a time when a massive wave of.. especially us old timers where our massive “$10” collections become as you guys suggest…
Come to the graves with us so to speak…
There must be some way future digital developers allow the passing on of someones digital collection like a house/business or something physical is passed onto the offspring… as long as everything can be honestly proved and accounted for…
Very good point you have made !
If I die, is my MS Windows 10 Pro OS invalidated or my MSFS not valid for anyone else to use.
I say NO, it belongs to the Account that registered it. And my PC will continue to operate in my absence if the account login continues to be valid because Mr. MS validated it for use on that particular computer no matter who turns it on. They have no idea what my name is… or who I really am and they do not care.
All they care about is that the software is licensed and authenticated. Just like the public use computers sitting in the lobby of the Holiday Inn Express ready for anyone to use. But, I cannot sell it, I get that.
Not sure why we focus so much on the MSFS? It is by far the cheapest purchase I made for my flightsim hobby.
Will whoever your PC, your joysticks etc and give them 100 bucks to buy MSFS.
True. MSFS is a bargain - both as a platform and with all the new free content arriving regularly.
If you buy a lot from the marketplace you can easily amass four digit sums that are all connected to your MSFS account and whether having that transferred is possible IS an interesting question.
