All planes or just commercial planes? Commercial planes try to avoid war zones, but you'll have other problems.

Maybe Antarctica?

I live near the Potomac River, which planes follow when landing at DCA, and hear quite a bit of aviation noise at home as a consequence. But I work in Maryland about 29km as the crow flies from IAD and about 60 km from BWI, and never hear any planes at all (general, commercial, or military; helicopters or fixed wing). I wouldn't think you should need to travel too far unless you live near a superhub.

I nominate the White House.

I feel like some of the answers to this question is pretty rough, and some additional context and/or motivation for the question would help. Is there a timeframe or other conditions to help define the answers?

Is it important to avoid planes actually overhead, or just ones you can see or hear.

Northern Ohio in January might work. We're so cloudy up here, we hardly ever see blue sky during the winter, let alone airplanes. Lots of horses and buggies, though!

On ISS you can see (nearly half of) operating airplanes but they are never above you. OTOH it's rather hard to qualify to go there, and definitely not restful and lazy.

I was going to suggest Pitcairn Island, but it looks like the great circle route from Papeete to Rapa Nui passes within 100 km, and there are two flights a week. Better not risk it.

Are you okay with being on a boat for that time, or would you prefer a land based location?

@dave_thompson_085: I think you overestimate how far from Earth the ISS is. It's in low earth orbit, about 400 km above sea level. You can see pretty far from that altitude, but not anywhere near half of the earth -- more like 1/30 of the earth's surface at any one time.

I found some global airline route maps using Google Image Search but @HenningMakholm pointed out that some of them were inaccurate.

Out of curiosity, do you have plans to fly there? ;)

Out of curiosity.... why?

I think the far side of the moon would satisfy all your requirements except for being on Earth.

FYI "Chemtrail" is a misnomer. You actually mean "contrail".

I'm voting to close as too broad and because the reference to chemtrails suggests that the question is not a serious request to solve "actual problems that you face" (help centre).

@Trotski94 But "chemtrail" is not a misnomer. Some people mean exactly the definition you'd find by googling it. Indeed, it might convey OP's rationale.

IMO this is too broad because of large geographical area? There are many places which may fulfil the criteria.

@L0j1k the same way OP wants some time to pretend planes don't exists, I like to dedicate my time to pretending people that actually believe wild conspiracies don't exist.

@Trotski94 which is a relief, because I like to dedicate my time to executing wild plans with co-conspirators. (JK!)

I expected to see an answer with math showing how far away you can see a contrail at 30k ft and more or less prove that such a place doesn't exist. Not seeing a plane is one thing, but I've seen contrails in my day that I believe were very far away.

When flying into JFK Airport in NYC they always fly in an illogical zigzag pattern over Long Island. I always assumed this was because of airplane noise laws in the areas they avoid.
