The aircraft type on your booking tells you more about comfort than the airline does. Here's a plain-English decode of the 787, A350, 777 and A320neo from an Indian flyer's seat — width, layout, noise and which to choose.
Quick answer
The aircraft type on your itinerary is the single best predictor of in-flight comfort. In 2026, here's the short version for flyers from India: the Airbus A350 and Boeing 787 are the newest-generation wide-bodies — quieter, with higher cabin humidity and lower cabin altitude, so you arrive less wrecked; the Boeing 777 is the older but spacious long-haul workhorse; and the Airbus A320neo/A321neo is the modern single-aisle that flies almost every domestic and short-international route. The comfort trap to avoid: on a 787 or 777, many airlines (including some Gulf carriers) pack economy 3-4-3, ten-abreast, which is tighter than the 3-3-3 nine-abreast the 787 was designed for. Air India's A350 flies 3-3-3 in economy. Always check the seat map for your specific aircraft before paying for a seat.
How to read the aircraft type on your ticket
Airlines list the equipment as a code: 32N or 32Q (A320neo/A321neo), 788/789 (Boeing 787-8/787-9), 359/351 (Airbus A350-900/-1000), 77W (Boeing 777-300ER), 77L (777-200LR). Two quick rules:
- The first digit family tells you size. 3 = Airbus narrow/wide (A3xx); 7 = Boeing (7x7). A "7" or "8" wide-body is a long-haul jet; a "32x" is single-aisle.
- The suffix letter/number tells you the variant. A 787-9 is a stretched 787-8; an A350-1000 is a stretched -900; a 777-300ER is longer than a 777-200. Longer variants carry more passengers, not necessarily more legroom.
What you actually want from the code is the seat layout, which the type only hints at — the airline chooses the abreast count. The reliable move: look up the exact aircraft on the airline's seat map (or SeatGuru/aeroLOPA-style tools) before selecting a seat.
Air India's 2026 fleet — what you'll actually fly
Air India is the carrier most Indians will meet across all these types, so its 2026 fleet is a useful map. As of early 2026 it operated roughly:
- 94 Airbus A320neo-family narrow-bodies — the domestic and short-international backbone. Air India completed a narrow-body retrofit in early 2026, adding a three-class layout (including premium economy) on select high-demand domestic sectors.
- 33 Boeing 787 Dreamliners (about 26 of the -8 and 7 of the -9). The 787 flies Air India's medium and long-haul — London, Frankfurt, Singapore and similar.
- 19 Boeing 777-300ER and 3 Boeing 777-200LR — the big, ultra-long-haul jets (the 777-200LR flies the nonstop US routes).
- 6 Airbus A350-900, configured 28 business + 24 premium economy + 264 economy = 316 seats, with A350-1000s arriving through 2026.
You can confirm the current fleet and per-aircraft cabin layouts on Air India's own fleet page before you book a long-haul seat.
The retrofit story matters: legacy 787s and 777s are going through a nose-to-tail refurbishment, so the same flight number can give you an old or a refreshed cabin depending on which tail operates it. For what to do when the aircraft swaps after you book, see our equipment-change guide.
The wide-bodies — 787 vs A350 vs 777
For long-haul out of India — Delhi to London, Mumbai to London, or onward to North America — the type genuinely changes how you feel on arrival:
- Airbus A350 — the most comfortable of the three by most measures. Carbon-composite fuselage allows higher cabin humidity and a lower effective cabin altitude (around 6,000 ft), large windows, and a notably quiet cabin. Air India flies it 3-3-3 in economy. Best long-haul economy experience in the Indian fleet.
- Boeing 787 Dreamliner — same generation as the A350: composite body, big electrochromic (dimming) windows, lower cabin altitude, smoother ride in turbulence thanks to gust-suppression. The catch is layout — designed for 3-3-3 (nine abreast), but many airlines squeeze 3-3-3.5 sense by going to a tighter seat. Check whether your operator flies it nine- or ten-abreast.
- Boeing 777 — older technology and a metal fuselage, so the cabin is drier and the windows smaller, but it's roomy and proven. The comfort variable is purely the airline's choice of 3-3-3 (more comfortable, ~10 inches wider seats) versus 3-4-3 ten-abreast (tighter, common on dense leisure configs). On the 777, the abreast count is everything.

The single-aisle — A320neo vs A321neo
Almost every domestic flight you take from India — Delhi to Bengaluru, Mumbai to Goa, Chennai to Delhi — is an A320neo or A321neo (or, on Akasa/SpiceJet, a Boeing 737). The neo ("new engine option") generation matters:
- A320neo — the workhorse. IndiGo typically configures it as 186 seats, all economy, 3-3 layout. New-generation engines make it noticeably quieter than the older A320ceo, especially at the back.
- A321neo — a stretched A320neo carrying more passengers (IndiGo runs 222 or 232 seats depending on the variant). Same 3-3 layout and seat width; it just has more rows. On a longer domestic or short-international sector you may find these on the route.
One technical note that occasionally reaches passengers: the neo family flies with one of two engine types — the CFM LEAP-1A (a direct-drive turbofan) or the Pratt & Whitney PW1100G geared turbofan (GTF). Both deliver around 15–20% better fuel burn than the previous generation. Engine choice is an airline/maintenance matter and doesn't change your seat — but GTF supply and durability issues have at times grounded aircraft industry-wide, which is one reason fleet reliability (and therefore on-time performance) varies between carriers.
How to use the aircraft type when you book
Turn the type into a decision:
- Long-haul comfort: prefer an A350 or 787 over a 777 if the fare and timing are close — you'll arrive measurably fresher thanks to lower cabin altitude and higher humidity. See how this interacts with timing in our red-eye vs day flights guide.
- Check abreast before paying for a seat: on a 777 or 787, confirm 3-3-3 vs 3-4-3/ten-abreast. Ten-abreast economy on a wide-body is tighter than a good single-aisle.
- Bulkhead and exit rows differ by aircraft — the same airline's 787 and A350 have legroom seats in different rows, so use the specific seat map, not a generic one.
- For families, bassinet positions are aircraft-specific; our flying-with-infants guide lists how to lock one in.

Frequently asked questions
Which is more comfortable, the Boeing 787 or the Airbus A350?
Both are newest-generation composite wide-bodies with lower cabin altitude and higher humidity, so both leave you fresher than older jets. The A350 is generally regarded as marginally more comfortable in economy, partly because airlines more often keep it at a roomier layout (Air India flies it 3-3-3). On either, check whether your operator uses a tight ten-abreast economy.
What does A320neo mean and is it better than the old A320?
Neo means 'new engine option' — the A320neo uses new-generation engines (CFM LEAP-1A or Pratt & Whitney geared turbofan) that cut fuel burn around 15–20% and run noticeably quieter than the older A320ceo. The cabin is the same 3-3 single-aisle; the main passenger-facing benefit is reduced engine noise, especially at the rear.
How many seats does Air India's A350 have?
Air India configures its Airbus A350-900 with 316 seats: 28 business suites, 24 premium economy and 264 economy in a 3-3-3 layout. It is among the most comfortable aircraft in the Indian fleet for long-haul economy. A350-1000s are joining the fleet through 2026.
What aircraft does Air India fly in 2026?
As of early 2026, roughly 94 Airbus A320neo-family narrow-bodies, 33 Boeing 787 Dreamliners (about 26 -8s and 7 -9s), 19 Boeing 777-300ERs, 3 Boeing 777-200LRs and 6 Airbus A350-900s, with more A350-1000s and 787-9s arriving during the year. Legacy 787s and 777s are being retrofitted, so cabins vary by tail.
Why is ten-abreast economy on a 777 or 787 less comfortable?
Both jets can be configured 3-3-3 (nine abreast) or 3-4-3/ten abreast. Ten abreast squeezes the same fuselage width into more seats, narrowing each seat by roughly an inch or more. A spacious single-aisle can feel roomier than a tightly packed wide-body, so always check the abreast count on the seat map before paying for a seat.
How do I find out which aircraft will operate my flight?
The aircraft type is shown at booking and on your itinerary as a code (e.g., 789 for a 787-9, 359 for an A350-900, 32N for an A320neo). For the seat layout, look up that exact aircraft on the airline's seat map. Note that the operating aircraft can change before departure due to an equipment swap.
