Buying flight 95 days prior to departure?

I don't understand your question. You can (usually) buy a ticket anywhere from roughly a year ahead to the day of your flight. Nothing stopping you other than maybe availability and price.

Do you mean, is it a good strategy to wait until 95 days before your flight to buy the ticket? If that's the question, the answer is usually no, that's often a way to buy an expensive ticket - but it depends on the details.

Yes I am asking "Do you mean, is it a good strategy to wait until 95 days before your flight to buy the ticket?"

It's really not a good idea to have a fixed plan like that unless you just don't care what you pay and are OK with picking from whatever options you see at that point. It will also help if your dates are somewhat flexible.

If your goal is to travel as cheaply as you can, you will probably do far better to look at your options today, narrow them down to perhaps 2 or 3 possibilities (again, flexible dates would be good), note the cost of each, and keep checking those costs--ideally every day. I use Google Flights, but there are other options like Kayak. Many of those website allow you to set a fare alert and will notify you when there's a significant change, but I don't depend on an automated notification system like that when so much money is at stake: I check myself, as often as I remember to.

If you monitor prices for awhile you will soon get a sense of the "normal" price range of each offering and can then spring into action if you see a great deal. Airfares on some routes gyrate a lot. After I bought the ticket for my summer 2018 trip (at just under $900, not a fabulous deal) in late 2017, I kept watching out of curiosity. The price jumped up to nearly $1400, then back down to about $900. Then it did the same thing at least two more times. Pretty mind-boggling. I felt sorry for anyone who happened to go flight shopping on one of the days when the fare was nearly $1400 and didn't know that fare was higher than it had been and might be again in a few days.

One pattern I've noticed is that the price gap between desirable routings (non-stop or one-stop) and more awkward routings (two-stop) tends to widen as you get closer to the departure date. So at 95 days out you might (no promises!) find a fairly reasonable price to Athens, but it might involve a 13-hour layover in Istanbul or a trip on an airline that I, personally, would like to avoid (e.g., Aeroflot). So your tolerance for a lengthy trip and oddball air carriers might also be a factor.

What is your origin airport? Some airports are easier/cheaper to fly from than others. The market to Athens isn't all that competitive even from major eastern cities like New York. If you're flying out of Cincinnati, Omaha, Spokane, etc., I don't know what you might get stuck with if you shop for your ticket in June.

I would like to leave from New England and a non stop flight.

You have not indicated where you are going, but based on other posts, I suspect it is Greece?

Every flight from "New England" is a non stop to somewhere.

Suggest you use skyskanner.com ( or you favorite search method) and plug in your origin airport(s) and destination and see what is available. If there is a non stop US to Athens flight, it is unknown to me. Not saying it does not exist, just that I have no info about such a thing.

Not sure that there is anything more magical about buying a ticket 95 days before departure than there is for 107, 82, or 93 days prior.

Even from Boston there are no non-stops. I checked the first seven days of September 2019. Lots of one-stop options at not-crazy prices. You'll have to weigh price versus location of your transfer and layover time. A too-short layover isn't a good thing. Personally, I'd prefer to change planes in Europe rather than the US or Canada, and I'd prefer not to transfer at London-Heathrow or Paris-Charles de Gaulle.

I just watch the airfares for a few weeks to get a feeling for what "normal" prices are where I'm going. I also look at airlines' calendars that show day by day the airfares. Often, Tuesday or Wednesday flights are the least expensive of any week--but airfares vary with supply and demand. I also keep my ear to the internet for special sales to pop up.
When airfares drop substantially, I'll buy the flights. Sometimes I win and sometimes I lost. But I mostly come out ahead. And I stay familiar with which airports are cheaper than others.
Another trick is to spot a flight to a "new city" that I want to go to. Very often airlines will price new flights very, very low to get flights full and get the route moving. I'm doing that going to Madrid the end of May.

And cheapest airfares are not necessarily the best total values. I spent one night in Boston in May after my return flight from Dublin, but I had to spend $200 for a hotel. And that is a cheap hotel for Boston where $350 a night rooms are "normal." I also try to get no more than one stop on any flight. And I don't choose to take flights and sit on the ground for 33 hours when I can spend just a little more and make the flight in 11 hours or so.

There have been several posts from people who paid several hundred dollars extra for their flights, because they followed dubious "experts" who told them to wait until 73.5 days before travel (or some such random number) to buy the tickets.

The problem with these numbers is that, even if they are not random, they are based on past performance. Just like a stock, past performance is not a guarantee of future performance. Also like a stock, you only know the lowest price once you've missed it.

If you want specific tips, we need to know exactly which airports you can use in the US, and exactly where you are going in Greece (assuming that is where you are going), as well as exact dates (or as close as you can come to this). All of these variables will affect prices. Prices for flights are no longer rational; it can be cheaper to fly longer distances. "New England" covers a lot of ground, and a cheap fare from Portland, ME won't be of much use if you live in Rhode Island.

There are very few nonstop flights from North America to Athens, and none of these run year-round. A great trick I learned on this Forum is that to see who flies where from a particular airport, look at that airport's Wikipedia page. Here's Athens airport: https://en.wikipedia.org/wiki/Athens_International_Airport#Passenger

Looking quickly, I see that North American destinations with service from Athens "in season" are JFK (Delta), Newark (United or Emirates), Philadelphia (American), Chicago (American), Toronto (Air Canada Rouge), and Montreal (Air Canada Rouge). Nothing to New England - alas. I don't know how long "the season" for flights to Athens is; I assume it's at least through September 30, but you would need to check each airline to make sure.

There will lots of one-stop options from Boston through European hubs, such as with Turkish Air through Istanbul or Aer Lingus through Dublin. Aer Lingus also serves Hartford. If you're originating from a different US airport than these, you'll probably do better to connect through a North American airport.

Start looking now at the routes you want, on Kayak or Matrix.ita or Google Flights. See what the options and prices are for your dates; play around with dates and routes if you have flexibility. This way, you'll learn the "regular" prices, and can spot a good deal. When you see a good price, pounce - it can be gone in an hour. Then stop looking, or you'll drive yourself crazy (since low fares are non-refundable, it's only going to lead to frustration to find a lower one that the one you're locked in to).

EDITED to clarify some points.

When to buy a ticket for a flight is one of most asked questions on travel forums. Normally you can start checking prices about 10 months before you travel.

I check prices almost daily and you can see wide fluctuations almost daily. Having said all that I bought a ticket from Boston to Athens this past Nov. for $745 through Delta. That's a pretty good price with short layovers going and coming back with nice departure/arrival times. It includes one checked luggage and seat selection. That price is lower than the first time we flew to Athens back in 2010! The lowest price I paid for a flight to Athens was $468 (Delta) back in 2015. It was a one-day price and then jumped quite a bit higher the next day.

Since I bought the latest ticket prices have jumped by almost $100. Will they come down, maybe. Will they go up, maybe.

The best answer is to buy the ticket when you feel the price is right for you.

There is no non-stop flights from Boston to Athens . . . always one layover somewhere, either in the US or Europe.

I would always buy a ticket through an airlines rather than a third-party.

The very last line in Harold's answer two posts up is important.

Don't burden yourself with "Buyer's Remorse".

Once you have made the decision on a good fare and jumped at it and made the reservation after reading the fine print and making sure - don't look back. All you will do is make yourself unhappy.

Do, however, keep an eye on the flight that you have bought. Airlines tend to revise schedules and connections - a lot. Keep checking that there hasn't been a change and an unpleasant layover or impossible connection. If things have changed and you don't like them, don't take it lying down. Come back for more advice, and contact the airline - very politely but firmly - and tell them what you want.

These articles promising the best day out, day of the week or time to buy are based on past performance, as Harold stated. But by following the above advice, you’ll quickly be able to discern using your own info and reject the click-bait info.

Airfares are highly specific as to origin/destination and date. Statistics-based recommendation are virtually always generic, and thus mostly useless. They're often downright dangerous because they convince novice travelers to wait for some arbitrary/theoretical/all-encompassing optimum purchase date when it is obvious to the experienced that it's far better to pay attention to market forces and seize a good opportunity if it presents itself.
