New Flights to Europe in 2027: Every Route, Priced

Twenty new nonstop routes between the United States and Europe have been announced for 2027. You can find that list in a dozen places.

What you cannot find anywhere else is the number that decides whether any of it matters to you: what that city-pair costs right now. We price 1,037 transatlantic fares across 26 US gateways, so this page does both — the announcements, and the fare each new route is arriving to compete with.

Where a new nonstop is actually worth something

Here is the same set, ordered by how expensive that departure city already is in our grid. This is the ordering that matters, because a nonstop into a market that is already cheap and well served changes very little.

New route	Destination	Gateway rank	Gateway median	That pair today
Delta AUS → CDG	Paris	#26 of 26	$792	$787
American CLT → BCN	Barcelona	#17 of 26	$749	$706
American PHL → OPO	Porto	#14 of 26	$738	$759
American PHL → VIE	Vienna	#14 of 26	$738	$656
American PHL → KEF	Reykjavik	#14 of 26	$738	$611
United DEN → CDG	Paris	#12 of 26	$713	$649
Alaska SEA → ATH	Athens	#7 of 26	$665	$680
Alaska SEA → CDG	Paris	#7 of 26	$665	$690
United IAD → MXP	Milan	#5 of 26	$651	$628
American JFK → AMS	Amsterdam	#1 of 26	$574	$569
American JFK → NCE	Nice	#1 of 26	$574	$597
United EWR → VLC	Valencia	#1 of 26	$574	$614

Read that table from the top and the argument makes itself.

Delta's Austin to Paris is the most consequential new route on the list. Austin is the dearest of the 26 US gateways we price, at a $792 median, and Paris from Austin costs $787 today — connecting, because there has never been a nonstop. A first-ever transatlantic route into the most expensive gateway in the country has room to move a fare in a way that a fourteenth New York option does not.

Philadelphia is the other one to watch. Porto from Philadelphia costs $759 today, above Philadelphia's own $738 median — an unusually bad pair, and precisely the shape of market a new nonstop exists to fix. Vienna at $656 and Reykjavik at $611 are already better than the city's median, so expect less there.

Two of those three are firsts. Porto and Vienna have never been American destinations at all, and the airline says it will be the only US carrier flying to Vienna. Reykjavik is a return rather than a debut — American last served it in 2019, and it now arrives into a market where Icelandair prices the nonstop at $600 for our fixed comparison week.

The aircraft is why these routes exist

Something worth noticing in the fine print. Of the eleven announced routes where the airline named an aircraft, nine are A321-family narrowbodies — mostly the A321XLR. All five of American's new Philadelphia and New York routes are A321s; its only widebody addition is Charlotte to Barcelona, on a 777-200ER, and that is the one route on its list to a city it already serves.

That is the whole reason a list like this exists. Porto, Vienna, Ljubljana, Olbia and Terceira cannot fill a widebody from a single US city, and until recently that settled the question. A narrowbody that can cross the Atlantic changes which markets are viable, which is why the 2027 map is full of cities no US airline has ever served rather than a fifteenth frequency to Heathrow.

It also sets expectations honestly: these are single-aisle aircraft on seven-hour flights. Nine of them will feel like it.

Now read the same table from the bottom. American's new JFK to Amsterdam arrives on a pair that already costs $569, from the cheapest gateway in the country. It is a good route and it will be a fine flight. It is not going to change what you pay.

One caveat that changes how you read that table

Our fare grid takes the cheapest week in the six months after collection, which for an August 30, 2026 sweep means roughly September 2026 through February 2027. Those are off-season fares, and on our own reckoning summer roughly doubles them.

Now look at when these routes start: three in March, two in April, ten in May, three in June. Thirteen of the eighteen dated launches land in May or June, and three — Delta's Austin-Paris and both Alaska routes — are explicitly seasonal, running only to October.

These are summer routes, and the fares above are winter fares. So read the "that pair today" column as what the market charges when nobody wants to go, which is the fairest available measure of how structurally expensive a city-pair is. Do not read it as what you will pay in July on the new nonstop. That number will be higher, probably much higher.

This cuts both ways, and the Austin case is the clearest. Austin to Paris at $787 off-season is a bad fare for a quiet season — which is exactly why a nonstop has room to work there. But the first summer of a brand-new route, with one airline flying it and no competitor, is historically not when a fare is cheap. The structural case for Austin is strong; the case for booking its opening summer is not the same thing.

The aircraft is the story

Eight of the twenty new destinations are not in our 40-city fare grid at all:

Destination	Airline	From
Luxembourg, Luxembourg	United	EWR
Ljubljana, Slovenia	United	EWR
Olbia, Italy	United	EWR
Catania, Italy	United	EWR
Ibiza, Spain	United	EWR
Marseille, France	United	EWR
Terceira, Portugal	United	EWR
Toulouse, France	United	IAD

That is not a gap in our data. It is the finding. We price the 40 European cities that a US traveler can realistically reach, and these were not among them, because they were connection-only markets — too thin to fill a 767 twice a week.

The Airbus A321XLR is why that changed. A narrowbody that crosses the Atlantic makes a route viable at roughly half the seats a widebody needs, and the destination list reads exactly like that: Luxembourg, Ljubljana, Olbia, Catania, Ibiza, Valencia, Marseille. These are not hub markets. They are places people go in July.

The practical consequence for a fare-conscious traveler is real but narrow: a thin route flown by a small aircraft is not usually a cheap route. It removes a connection, which is worth something on its own, and it very occasionally opens a cheap fare while the airline builds the market. What it does not do is behave like the transatlantic trunk routes where competition sets the price.

When it arrives, should you take it?

A new nonstop is a convenience story before it is a price story, and the two get conflated constantly. So here is what a nonstop actually costs, using the one gateway where we have priced both sides of the same route.

Destination	Nonstop	Cheapest any routing	What the straight line costs
Reykjavik	$449	$449	None
Porto	$555	$555	None
Copenhagen	$598	$554	$44
Barcelona	$562	$499	$63
Rome	$670	$562	$108
Paris	$719	$558	$161
London	$780	$574	$206
Milan	$862	$591	$271
Athens	$1,001	$655	$346

Across all fifteen Boston routes we priced this way, the median premium for flying nonstop is $118, and the range runs from nothing at all to $346.

Two of them — Reykjavik and Porto — price identically nonstop and connecting, which makes the decision trivial. Seven of the thirteen that do carry a premium sit under $120, which for a transatlantic redeye is defensible for most people. Athens at $346 and Milan at $271 are where you should genuinely stop and think, because that is real money for a few hours.

The reason this matters on a page about new routes: when Delta's Austin-Paris opens, the useful question is not "is there a nonstop now" but "what is the nonstop charging over the connection it replaced". On the evidence from Boston, expect somewhere around $120 on a mature route — and expect it to be worse than that in the first season, while the airline is the only one flying it.

What to actually do with this

1. Do not wait for a 2027 route to book a 2026 trip. Every start date here is March at the earliest, and most are May or June.
2. If you fly from Austin, Philadelphia or Charlotte, this is genuinely your news. Those are the gateways where our grid says the current fare is worst relative to the country.
3. If you fly from New York, it mostly is not. Three of the twenty serve a metro that is already the cheapest gateway we price.
4. Treat the thin XLR routes as convenience, not savings. A three-times-weekly flight to Olbia is a better trip; it is not a cheaper one.
5. Price the connection anyway when the route opens. On our Boston data the straight line costs $118 more at the median, and on two routes it costs nothing.

Where this page's information comes from

Every other dataset on this site is first-party: we priced it, or we verified it. This page is the exception, and it should be read differently.

Route announcements are corporate news. We did not confirm these schedules ourselves. Where the airline has published the announcement itself we cite that rather than the outlets reporting it, because for a fact the airline states plainly, a secondary source is simply a worse citation.

Two dates were unsettled, and going to the airline settled them. United's Ljubljana was given as April 2 by one outlet and May 12 by another; Olbia as May 28 and May 27. Rather than pick the more convenient number, both sat here marked disputed — and then United's own announcement gave May 12 and May 27, which is the argument for preferring a primary source over the coverage of it.

That is now the rule for this page. Seventeen of the twenty routes cite the airline's own newsroom, and the three that do not are the ones where no airline release exists. The disputed-date mechanism stays, because the next disagreement will not always be resolvable — it is the same rule that keeps unconfirmed credit-card earn rates out of our points guidance.

One more absence worth naming. American has said seven further European destinations will be announced closer to summer 2027, and some coverage has already attached specific cities to that plan. Those cities are not on this page. An airline evaluating a market is not a route, and the distance between the two is where most bad travel reporting lives.

Method

Route data is secondary, sourced and dated as above.

Fare data is ours: the cheapest one-week economy round trip found for each city-pair in the six months after August 30, 2026, across 26 US gateways. Gateway rank and median come from the same grid. Where a new route serves a city we do not price, the fare columns are empty rather than estimated.

Once these routes actually fly, they stop being news and become fares — at which point they enter the grid and we can price them ourselves instead of citing anyone.

The routes leaving before any of these arrive

Every list like this counts arrivals, which flatters the market. Six US-Europe routes still bookable today stop before the first 2027 route starts, and those are the more actionable ones — a route that ends in four weeks is a decision now; a route that starts in eighteen months is not.

Route	Carrier	Last day	How full it was
Denver → Dublin	Aer Lingus	September 28, 2026	64.1%
Minneapolis → Dublin	Aer Lingus	October 24, 2026	61.8%
Seattle → Dublin	Aer Lingus	October 24, 2026	Winter only; summer stays
Boston → Barcelona	LEVEL	October 25, 2026	Not published
Los Angeles → Barcelona	LEVEL	October 25, 2026	Not published
Las Vegas → Dublin	Aer Lingus	December 3, 2026	71.3%

Aer Lingus is losing five US routes in the same year it planned its largest ever transatlantic schedule. Three of them were published with load factors, which is unusually candid, and the numbers explain the decision better than any statement could: 61.8%, 64.1% and 71.3%. A transatlantic widebody does not work at those levels, and the reason they got there is the same reason the 2027 list is so long — transatlantic capacity rose 45% in winter 2025/26, and someone had to lose.

Notice what that means for the new routes above. The A321XLR is opening thin markets precisely because thin markets are where widebodies fail, and Denver, Minneapolis and Las Vegas to Dublin are what widebody failure in a thin market looks like. The narrowbody is not just an efficiency story; it is the aircraft that would have made these routes survivable. Whether it makes the 2027 crop survivable is the open question, and 2028 will answer it.

The full list, including the three that have already operated their last flight, is on our routes-ending tracker. If you were counting on one of these, book before the last date or reroute now. Boston and Los Angeles to Barcelona both leave a market where Barcelona is already reachable for $499 from Boston, so the fare damage should be limited — but the nonstop is going.
