The fares are almost identical.
And both aircraft have excellent reputations for long-haul flying.
So you might assume it doesn’t matter which one you choose.
But spend 10 or 12 hours in Economy and the differences begin to matter.
Cabin width.
Seat configuration.
Noise.
Windows.
Cabin environment.
And perhaps most importantly, the way the airline has configured the aircraft.
The A350 and 787 represent two of the most advanced long-haul aircraft families flying today but that doesn’t necessarily mean they deliver exactly the same passenger experience.
So if your booking screen gives you a genuine choice, which should you take?
Let’s compare the Airbus A350 vs Boeing 787 Economy experience from the perspective that matters most:
the passenger actually sitting in the back.

SkypropreAir Verdict
If the airline, fare, schedule, seat position and journey time were broadly equal, SkypropreAir would choose the Airbus A350 in Economy Class.
Why?
Not because the Boeing 787 is uncomfortable.
Far from it.
The 787 is one of the most passenger-friendly long-haul aircraft of its generation.
But the A350’s wider cabin and reputation for an exceptionally quiet passenger environment give it a small advantage when you’re spending many hours in Economy.
There is, however, one rule worth remembering throughout this comparison:
A well-chosen seat on a well-configured Boeing 787 can easily beat a poor seat on an Airbus A350.
The aircraft matters.
The airline and seat matter even more.
✈️ Before You Book: Compare More Than the Fare
Found an A350 and 787 flying the same route?
Don’t automatically choose the cheapest ticket.
Compare the airline, aircraft, journey time, departure time and fare first.
👉 Compare long-haul flight options with Aviasales
Then check the seat map before paying.
Sometimes the more comfortable option costs exactly the same.
1. Seat Comfort: Why Cabin Width Gives the A350 an Advantage
This is where the comparison becomes particularly important for Economy passengers.
Both aircraft commonly operate with nine Economy seats across in a 3-3-3 configuration.
But their cabins aren’t identical.
The A350 has a wider passenger cabin than the 787.
That doesn’t automatically guarantee you a wider seat because airlines determine their own cabin configurations.
But it gives airlines more physical space to work with.
Depending on the operator, that can influence seat width, aisle space and the overall feeling of the cabin.
And seemingly tiny differences become more noticeable as a flight gets longer.
At hour one, a fraction of extra shoulder room may seem irrelevant.
At hour nine, particularly with passengers sleeping beside you — it can feel much more important.
Winner: Airbus A350
But don’t book purely by aircraft type.
Check the airline’s actual configuration first.

2. The Middle-Seat Problem: Neither Aircraft Completely Solves It
There is one weakness shared by most A350 and 787 Economy cabins:
3-3-3 means middle seats.
For solo travellers, avoiding the middle position can make a greater difference to comfort than choosing between these two aircraft.
Window passengers gain somewhere to lean while sleeping.
Aisle passengers gain easier access to the cabin and lavatories.
Middle-seat passengers get neither advantage.
Couples face another problem.
A typical 3-3-3 configuration doesn’t provide the natural pair of seats available on many Airbus A330 cabins using 2-4-2.
If travelling as a couple, that distinction may actually influence your aircraft choice more than the A350-versus-787 debate.

3. Cabin Noise: Why It Matters More Than You Think
Cabin noise is easy to underestimate.
For the first hour, you may barely notice the continuous background sound.
After eight, ten or twelve hours, however, the environment surrounding your seat becomes part of the overall fatigue equation.
The A350 was designed with acoustic comfort as an important part of its passenger experience.
The 787 is also a modern, relatively quiet long-haul aircraft.
Neither should be confused with some older-generation cabins where continuous engine and airflow noise can be considerably more noticeable.
But for an overnight flight where sleeping is a priority, the A350 gets our narrow advantage.
Winner: Airbus A350
Your seat position still matters.
A quiet aircraft won’t feel particularly peaceful if you’ve selected a seat beside a galley where crew activity continues through the night.

4. Cabin Pressure and Air: The Hidden Battle You Don’t See
Passengers usually compare seats, meals and entertainment.
They rarely think about the atmosphere they’re sitting in.
Yet cabin environment is one of the most interesting similarities between these aircraft.
Both use extensive composite materials and were designed with modern long-haul passenger comfort in mind.
Airbus describes the A350 as offering a cabin altitude of around 6,000 feet in typical cruise conditions, together with advanced cabin-air management.
Boeing likewise designed the 787 around a lower cabin-altitude environment than many older aircraft types.
Why might that matter?
After a long flight, passengers can experience:
- tiredness
- dry eyes
- dry throat
- general discomfort
No aircraft can eliminate long-haul fatigue or jet lag.
But improving the cabin environment is one part of making a very long journey more tolerable.
Winner: Tie
This is one area where both aircraft represent the modern generation of long-haul travel.
5. Windows: This Is Where the 787 Hits Back
Choose a window seat on a Boeing 787 and one difference becomes obvious almost immediately.
The windows are huge.
They’re one of the Dreamliner’s signature passenger features.
Instead of pulling down a conventional shade, passengers can adjust the window tint electronically.
The large windows also allow passengers sitting further inside the cabin to see more of the outside world.
That may sound like a cosmetic feature.
But on a daytime long-haul flight, the additional light and visual connection with the outside world can make the cabin feel significantly more open.
The A350 offers a modern window experience too.
But this category belongs to Boeing.
Winner: Boeing 787
If you’re someone who chooses a window seat specifically for the view, the 787 may actually be your preferred aircraft despite the A350 winning overall.
6. Which Aircraft Feels More Spacious in Economy?
Here’s where technical measurements meet human psychology.
Passengers don’t experience aircraft through specification sheets.
They experience space.
Seat density, overhead bins, ceiling design, lighting, sidewalls, windows and aisle width can all influence whether a cabin feels open or claustrophobic.
The 787 performs exceptionally well here.
Its large windows and modern cabin architecture help create a bright, contemporary environment.
But the A350’s wider cabin gives it a natural advantage.
That doesn’t mean every A350 seat will be wider than every 787 seat.
It means the aircraft gives airlines a larger canvas on which to design the Economy cabin.
Winner: Airbus A350
7. Which Is Better for Sleeping?
This question matters enormously on an overnight flight.
Sleeping successfully in Economy depends on several things:
- seat position
- recline
- cabin noise
- temperature
- neighbouring passengers
- lavatory traffic
- galley activity
- turbulence
- and whether anyone needs to climb over you.
The A350’s quiet cabin environment gives it a slight advantage.
But here’s the important part:
Seat selection can completely reverse the result.
A window seat in a quiet section of a 787 could be considerably better for sleeping than an A350 aisle seat directly beside the lavatories.
So don’t choose the right aircraft and then select the wrong seat.
SkypropreAir Tip
Before paying for seat selection, check the actual aircraft configuration on a detailed seat-map resource such as AeroLOPA.
Look specifically for:
- lavatories
- galleys
- bassinets
- bulkheads
- exit rows
- missing windows
- last-row seats
- possible recline restrictions
Then compare that information with the airline’s own seat map.
Aircraft selection gets you onto the right plane. Seat selection determines where you’ll spend the next 10 hours.

8. What About Turbulence?
Passengers sometimes ask:
Is the A350 smoother than the 787?
There isn’t a simple aircraft-versus-aircraft answer.
Turbulence is primarily an atmospheric phenomenon.
Weather systems, jet streams, convection and clear-air turbulence can affect any aircraft.
Where you sit can, however, influence how much movement you perceive.
Seats closer to the wing area generally experience less noticeable pitching movement than seats toward the extreme rear of the aircraft.
So don’t choose an A350 or 787 because you believe one is somehow immune to turbulence.
Neither is.
Choose your seat strategically and keep your seat belt fastened whenever you’re seated.

9. The Airline May Matter More Than Airbus vs Boeing
This is probably the most important lesson in this entire comparison.
Airbus doesn’t choose your Economy seat.
Neither does Boeing.
The airline decides:
- seat model
- seat pitch
- seat width
- padding
- recline
- entertainment
- cabin density
- Economy configuration
- onboard service
That’s why two flights operated by exactly the same aircraft type can feel remarkably different.
So when comparing long-haul Economy flights, use this hierarchy:
SkypropreAir Booking Formula
1. Airline configuration
2. Seat map
3. Aircraft type
4. Individual seat
5. Schedule and journey time
6. Price
Aircraft knowledge should help you make a better decision.
It shouldn’t cause you to ignore everything else.
10. A350 vs 787: Which Traveller Should Choose Which?
Solo Traveller
🏆 A350 — narrow win
The wider cabin is attractive, but choosing an aisle or window seat matters considerably more.
Couples
🏆 Tie
Neither aircraft’s common 3-3-3 configuration is ideal if you want a private pair.
An A330 with 2-4-2 seating may actually suit you better.
Overnight Traveller
🏆 A350
The quiet cabin environment gives it the edge.
Window-Seat Traveller
🏆 Boeing 787
This is where the Dreamliner shines.
Ultra-Long-Haul Traveller
🏆 A350 — narrow win
Cabin width, quietness and the overall passenger environment make it particularly compelling as flight time increases.
Passenger Choosing Purely on Price
🏆 Neither
If the 787 saves you €150 and gives you a good seat on a nonstop flight, don’t spend substantially more just to fly an A350.
11. The €25 Question: Would We Pay More to Fly the A350?
This is where we turn the comparison into an actual booking decision.
Suppose you’re looking at two comparable nonstop flights.
A350 flight: €625
787 flight: €600
Would we pay another €25 for the A350?
Potentially, yes — particularly for an overnight or very long flight.
Now make the difference €150.
Would we still choose the A350 purely because of the aircraft?
Probably not.
And if the cheaper 787 is nonstop while the A350 requires a connection?
We’d take the 787.
That’s the key.
Aircraft type should be a tiebreaker, not the entire booking strategy.
12. Before Clicking “Book,” Do This 60-Second Check
You’ve found your flight.
Before entering your payment details, spend another minute checking:
1. What aircraft is scheduled?
A350? 787? A330? 777?
2. What Economy layout does that airline use?
Don’t assume every aircraft with the same name has identical seats.
3. Where are the lavatories and galleys?
Avoid unnecessary noise and foot traffic.
4. Is your preferred seat actually available?
A great aircraft doesn’t help much if only undesirable seats remain.
5. Is the aircraft advantage worth the fare difference?
Sometimes yes.
Sometimes absolutely not.

Then check the airline seat map before completing your booking.
Final Verdict: The A350 Wins — But Only Just
The Airbus A350 vs Boeing 787 Economy contest doesn’t produce a dramatic winner.
That’s because both aircraft are excellent long-haul platforms.
Choose the Airbus A350 if you prioritise:
- cabin spaciousness
- low cabin noise
- overnight comfort
- very long journeys
Choose the Boeing 787 if you prioritise:
- large windows
- electronic window dimming
- a bright, modern cabin
- a particular airline, schedule or better fare
If everything else were equal:
🏆 SkypropreAir Economy Winner: Airbus A350
But the most important sentence in this article isn’t the winner.
It’s this:
A great seat on a Boeing 787 is better than a bad seat on an Airbus A350.
Choose the airline.
Check the configuration.
Study the seat map.
Compare the fare.
Then choose the aircraft.
