Today (August 11, 2017): The A350 vs B787 Dreamliner: which one is best?

The A350 and B787 Dreamliner are the world’s most advanced airplanes, produced respectively by Airbus (Europe) and Boeing (USA). The latter was the first of the two companies to introduce the concept of a revolutionary new and fuel-efficient plane. The first B787 was unveiled in 2007 during a roll-out ceremony at Boeing’s factory near Seattle, although it took another 2 years for the maiden flight (2009) and 4 more years for the first commercial flight (2011, All Nippon Airways) since the prestigious project suffered a series of massive delays. The A350 was originally conceived in 2004 as an improved version of the A330, featuring the same fuselage albeit paired with new aerodynamic features and engines. However, in 2006, Airbus was forced to rethink its aircraft model in response to Boeing’s B787 project and consequent criticism by the airlines that the new Airbus plane was not revolutionary enough. After a complete redesign, the first A350 took off in 2013, while the first A350 entered passenger service two years later with its launch customer, Qatar Airways. I have been lucky to fly on both aircraft types, and I have previously published several trip reports about these experiences:

While they are not direct competitors – the A350 competes more with the B777 than the B787 – the two long-range, wide-bodied, twin-engine aircraft are often compared one to another since they feature the aviation industry’s newest gadgets and technologies. They both offer a big saving in fuel costs relative to the number of passengers they carry, which makes them very popular with carriers: as of today, Boeing has orders for more than 1,200 B787 Dreamliners from 67 customers, while Airbus had received more than 800 orders for A350s from 46 customers worldwide, already making both plane types two of the most successful widebody aircraft ever. The most revolutionary features shared by both planes can be summarized as follows:

  • The A350 and the B787 are the first large commercial aircraft to be constructed extensively from lightweight composites. Airbus and Boeing use reinforced plastic composites in respectively 53% and 50% of the A350 and B787 fuselage respectively. The main advantage of composites is that these components are lighter than similar parts made of aluminium (which means a lighter aircraft and thus less fuel burn). In addition, carbon-fibre reinforced polymers or plastics have increased resistance to corrosion and don’t suffer from fatigue to the same extent as aluminium, which translates into more durable airframes and lower maintenance costs.
  • Carbon fibre composites are also stronger than aluminium, which allows the skin of a B787 or A350 to tolerate a higher degree of pressurization. At high altitudes, there is less pressure in the outside air and thus less oxygen available in a given breath, hence why conditioned air is pumped (or ‘pressurized’) into an aircraft to simulate a lower altitude inside the cabin and create a survivable and comfortable environment above 14,000 ft (4,300 m). While conventional aircraft are pressurized at 8,000 ft (or 2,400 m), the Boeing 787 Dreamliner and the Airbus A350 are pressurized to 6,000 ft (or 1,800 m). This 2000 ft (or 600 m) in difference means that there is more oxygen and moisture in the air inside a B787 and A350, resulting in a noticeable increase in passenger comfort. This higher cabin pressure reduces the risk of dry eyes and skin, headaches, severe jetlag, respiratory problems, and the formation of blood clots in deep veins (deep venous thrombosis).

I am not an aviation expert, but having flown several times on both aircraft types and often getting the question which one I like the most, I decided to share with you my opinion and preference on the A350 vs the B787. IMHO, both planes offer a very similar experience from a passenger’s perspective, which far exceeds the one offered onboard older, more conventional aircraft types (except for the A380, which is still my favorite aircraft), although there a few subtle difference. You can share your own opinion in the comments section or take my poll below.

  • The A350 has a tail camera while the B787 doesn’t have one. I am one of those passengers who likes to follow the plane’s movements on the TV screen as it takes off or lands, so the A350 is clearly the winner here. In addition, I am a nervous flyer, and having a wide, frontal view via the tail camera instead of the narrow side view via the window eases my anxiety and makes me feel more relaxed. It has to be noted that the A350 tail camera is offered as an option by Airbus to its customers, and Singapore Airlines is so far the only airline that somewhat incomprehensibly decided not to install one.
  • The B787 features the largest windows in the industry, about 65 per cent bigger than a standard airline window. And Boeing took it even one step further by providing first-of-its-kind touch pad controls to electronically dim the windows on the B787. Despite this fancy feature, which is fun the first time you try it out, I am not a fan of the B787’s electro-chromatic dimmable windows and prefer the A350’s old-fashioned, pull-down blinds (albeit the A350’s windows are not as large as on the B787). The problem with the Dreamliner is that it can take up to 5 minutes to dim or brighten your window. Also, in some airlines (such as British Airways) the cabin crew has the option to electronically dim all windows at once and you can’t override that command at your own seat. In addition, the shutter-less windows remain translucent at their darkest setting, although they can be dimmed sufficiently for sleep and watching videos. Apparently, I am not the only one who dislikes the B787’s dimmed windows, since some airlines have retro-fitted pull-down blinds over their Dreamliner’s windows.
  • The fuselage of an A350 is around 5 inches or 13 centimeters wider than its counterpart of the Boeing 787 Dreamliner. It may not sound like a major difference, but with nine seats abreast in Economy Class – the current standard configuration in both aircraft types – the extra half inch or 1,4 cm per seat in the A350 does make the flight experience more comfortable. However, that difference may soon turn out in the favor of the Dreamliner since Air Caraibes will be the first airline to install 10 seats per row in its A350 planes, which will be worse than 9 abreast on the Dreamliner and might be the new trend for the A350. Nevertheless, IMHO, the A350 feels very spacious – even in Business Class – because of its straight side walls and almost flat ceiling – the tallest ceiling of any commercial aircraft – with extra large overhead bins, especially when compared to the B787’s visually relaxing but more cramped design with sweeping archways.
  • Both the Dreamliner and A350 have far quieter cabins than conventional aircraft. And the A350 is even more quiet than the B787 Dreamliner, thanks largely to the Automatic Noise Abatement Departure Procedure (NADP), which optimises the thrust and flight path to reduce noise, and to its giant low carbon emission custom-designed Rolls Royce Trent XWB, the most fuel efficient and cleanest (in terms of emissions) engine flying today. In fact, the A350’s cabin is the quietest of any twin-aisle aircraft, with a typical noise level of 57 decibels in the cabin at cruising altitude, about equal to the volume of a normal conversation. It has to be noted that the A350’s big brother, the A380, has an even quieter cabin, which is especially noticeable when you are seated on the upper deck.
  • When you are a First Class addict, you have to avoid flying on a A350 at all costs since none of its operators (e.g. Singapore Airlines, Qatar Airways, Finnair, LATAM, Cathay Pacific and China Airlines to name a few) has installed a First Class cabin onboard the plane (and it doesn’t look like they will any time soon). In contrast, the B787-9 Dreamliner aircraft that are part of the fleet of British Airways and Etihad Airways do feature a First Class cabin.
  • If you are a nervous flyer, you better stop reading. While designing the plane, Boeing decided to install powerful lithium-ion batteries on the B787, which offer greater capacity for less weight and, if required, more opportunities to power aircraft systems. However, this new and rather immature technology caused major safety problems. In 2013, all 50 B787 Dreamliners in service were grounded for multiple months after fires broke out on an All Nippon Airways and Japan Airlines B787 in two unrelated incidents, both caused by thermal runaway events of the lithium-ion batteries. The USA’s National Transportation Safety Board investigated the incidents and assigned blame to several groups, including the Japanese battery manufacturer and Boeing for not catching the problem earlier. To make the B787 airworthy again, Boeing redesigned the battery and charger and designed a steel box to contain fires and vent hot gasses outside the plane. However, following another battery fire incident onboard a Japan Airlines B787 during routine maintance in 2014, there is concern among some aviation experts that the solutions put in place by Boeing are not able to cover the full range of possible failure modes and that Boeing does not understand the root cause of the battery failure. It’s an uneasy thought that always flashes through my mind when I have to fly the B787 across a large body of water or wilderness, where no airport is immediately available in a worst case scenerio. In the wake of the Boeing 787 Dreamliner’s battery fires, Airbus decided to drop Lithium-Ion batteries and switched to traditional nickel-cadmium batteries for its A350 passenger jet.

In summary, I clearly prefer the A350 over the B787, mainly because of the quieter, wider and taller cabin, but also because of the plane’s conventional pull-down blinds and lack of documented battery problems.

What’s your favorite aircraft: the A350 or the B787? You can leave a comment below or take my poll.

  1. A350, quieter, wider cabin, and no battery issues, which is a concern for me on some of the long over water routes the 787 flys.

  2. After flown the 787 of Qatar in economy class, I really try to avoid that plane. I’m quite small and tiny, so economy never feels cramped for me… untill I’ve flown the 787. It is mainly because of the seat width, which is smaller than the A320 seats… And that’s not OK for long haul. I only would consider it again if I had a JAL 787 flight, as they are the only airline flying the plane like it was meant to be (2-4-2 in economy, rather than 3-3-3). I really wonder what the configuration will be on SQ’s 787-10… If really hope they will also go fo the 2-4-2 configuration. The A350 cabin is wider, so this one is probably fine in economy, but I’ve never flown it so far…

    PS: I really don’t understand that QR can be a 5 star airline. OK, for business and first it is probably wel deserved, but I wonder if all those Skytrax jury members after a long haul 787 economy class flight would still go for the 5 stars… For economy passengers 787’s are really not good, even on those so called ‘5 star’ airlines. It’s better to fly most 3-4 star airlines flyinger with older but wider equipment.

  3. Biased review. To avoid being biased, provide numbers for each aircraft for readers to draw conclusions (eg, dB for noise in each, not just for A350)

  4. It’s widely known that Airbus planes are quieter. A380 vs 747/777. A350 vs 787. I have flown on all these aircraft multiple times and the difference is very obvious!

  5. The cabin pressure and air humidity is better on the 787. You arrived after a long flight less tired. I also think 9 across on a 787 is much, much, much better than 10 across on an A350. The sweeping lines are more aesthetically pleasing on the 787 than than the boxy A350. But the best part are the extra large windows. Very unique. It makes the plane feel much larger. All in all, the 787 is the clear winner here.

  6. And what about smaller space? It feels really cramped the 787, the A350 is clearly wider. And regarding windows, art leat me, I hate them, so bigger windows would be a negative. And even for someone liking light, a slightly bigger windows would not compensate traveling in a more cramped space.

  7. Just came back from a trip (11th Sept) with a transit. Both planes were Singapore Airlines. First was the brand new 787-10 (3.5 months old) and 2 hours later, it was the A350-900… I’d prefer the latter. It’s wider and quieter (surprisingly the 3.5 month old 787-10 creaks more) and the A350’s entertainment system seems more suited for kids which is good for long hauls. I believe both planes look good but just dig that curved shark-tip on the A350’s wing and that batman look for the cockpit! Looking forward to a long haul in A350 in the near future.

  8. Not at all. Less comfortable. Noise, space, humid. and cabin pressure about the same. Both are ok but Airbus better.

  9. Such a pointless biased article.

    People fail to realise Boeing reinvented how planes could be built. Tail fin camera – give me a break?!
    Google ‘Bleed air systems’
    Boeing ditched it for dedicated purified air intake which is why you don’t get poisoned on a 787 and feel refreshed. Every other plane sucks air via the engines.

  10. Aesthetically, I like the sleek beautiful shape of the A350 compared to the humpty B787 when you see them taxiing on the ramp at airports. Also the stick looks more modern than the yoke, for the pilots. With the Airbus, you can decently eat your meals with a table in front of you.

  11. Cadillac vs BMW. Apple vs Microsoft. ? Which one. There are distinct engineering differences on how they make those products which make you feel or decide which is better. To nitpick would be very difficult.
