Airbus vs Boeing: What's the Difference and How to Tell Them Apart
Two companies make almost every commercial airliner you'll ever fly on. Airbus and Boeing together account for roughly 99% of the global narrowbody and widebody jet market. But how different are their aircraft really — and can you tell them apart from the ground?
A Brief History of the Rivalry
Boeing has been building commercial aircraft since 1958, when the Boeing 707 entered service and effectively created the modern jet age. Through the 1960s and 70s, Boeing dominated with the 727, 737, and the iconic 747 — the "Queen of the Skies" that defined long-haul travel for decades.
Airbus was founded in 1970 as a European consortium (initially France, Germany, and the UK, though the UK withdrew early) to challenge American dominance of the aviation market. Its A300 — the world's first twin-engine widebody — entered service in 1974. Progress was slow at first, but Airbus's radical A320 in 1988 changed everything: it introduced fly-by-wire controls to commercial aviation and quickly took half the narrowbody market.
Today, both companies have waiting lists stretching years into the future, and airlines typically operate both types.

How to Tell Them Apart: Visual Differences
Nose Shape
This is the most reliable visual indicator from the ground:
Airbus aircraft have a rounded, drooping nose with a slightly blunt appearance. The cockpit windows are shaped differently — smaller and more rectangular in older designs, giving a distinctive look.
Boeing aircraft tend to have a more pointed, angular nose with a slightly sharper profile. The 737's nose in particular is very distinctive — narrower and more tapered than its Airbus equivalent.
Winglets
Both manufacturers use winglets (upturned wingtip devices that reduce drag), but the styles differ:
Airbus:
- A320 family uses "sharklets" — tall, gently curved winglets that blend smoothly into the wingtip
- Older A320ceo aircraft may have no winglets or small blended winglets
- A330neo has large curved winglets
- A350 has very large, gracefully curved wingtips integrated into the wing shape
Boeing:
- 737 Classic and 737NG (800/900) typically have blended winglets — angled upward with a smooth curve at the base
- 737 MAX has distinctive split scimitar winglets — the main winglet angles up while a smaller "fence" angles downward
- 787 Dreamliner has very long, dramatically raked wingtips (no traditional winglet — the tips curve upward naturally)
- 777X has folding wingtips — a first for commercial aviation
The Tail
Airbus A320 family: The tail has a distinctive APU exhaust at the very tip of the fuselage — a small pipe visible at the tail end. The tail cone is relatively blunt and rounded.
Boeing 737: The tail cone is more pointed and tapered, and the APU exhaust exits at a different position.
Engine Placement
Boeing 737: Due to its low ground clearance (the original 737 was designed in the 1960s for airports without jetways), the 737's engines cannot hang below the wing like most jets. Instead, they're pushed forward and positioned above the wing line, giving them a flattened bottom on the nacelle. This is one of the most distinctive 737 features.
Airbus A320 family: Engines hang below the wing in the conventional position, more circular in cross-section.
On the 737 MAX specifically, the LEAP-1B engines are so large that they create the famous flat-bottomed nacelle effect — the engine is noticeably oval rather than round.
The Cabin Cross-Section
From below, you can sometimes judge cabin width:
- A320 family: 3.95m fuselage diameter — slightly wider than the 737
- 737 family: 3.76m fuselage diameter
This makes the A320 slightly more spacious, which is why passengers often find it more comfortable. From the ground, it's nearly impossible to judge, but side-on you might notice the A320's fuselage looks marginally taller.
Fly-By-Wire: The Philosophical Difference
One of the most significant differences between the two manufacturers isn't visible at all — it's in how the aircraft fly.
Airbus: Fly-By-Wire with Flight Envelope Protection
Airbus introduced full fly-by-wire in the A320. In an Airbus aircraft, the computers interpret pilot inputs and apply flight envelope protection — they will refuse to execute commands that would put the aircraft outside safe operating parameters.
For example:
- If a pilot pulls back hard, the aircraft won't exceed maximum pitch or G-force
- If the aircraft is approaching stall speed, the computers will resist further pitch-up commands
- Airbus uses a sidestick controller (not a traditional yoke) — there is no direct mechanical link between the sidestick and the control surfaces
Boeing: Fly-By-Wire with Pilot Authority
Boeing's philosophy is different — even with fly-by-wire systems (used on the 777, 787, and 777X), Boeing retains pilot authority. The computers provide feedback and warnings, but pilots can override protections if they judge it necessary.
- Boeing retains the traditional yoke (control column) in most aircraft
- Pilots have full authority to exceed envelope parameters — which some argue is safer in unusual situations, and others argue creates risk
- The 737 (including the MAX) is not truly fly-by-wire — it uses a hybrid system with some electronic and some mechanical controls
The 737 MAX's MCAS (Manoeuvring Characteristics Augmentation System) — the system implicated in the two fatal crashes in 2018/2019 — was a software layer added to manage pitch handling characteristics. Its failure and the subsequent crisis reshaped the relationship between Boeing and regulators worldwide.
From an Airline's Perspective: Why Choose One Over the Other?
Airlines consider many factors:
Fleet commonality: If you already operate A320s, adding A321neos makes sense — pilots are cross-qualified, maintenance tools and parts are common, simulators are shared.
Manufacturer relationships and pricing: Both manufacturers offer significant discounts on large orders. The negotiated price bears little relationship to the list price.
Performance on specific routes: The A321XLR, for example, gives airlines transatlantic single-aisle capability that Boeing cannot currently match. Conversely, the 777X's capacity suits specific high-density routes better than anything Airbus currently offers.
Delivery slots: With both manufacturers massively backlogged (Airbus's delivery backlog is over 8,000 aircraft), airlines sometimes choose based on who can deliver sooner.
