How many seats does an Airbus A330 have?

Depends on the airline's configuration. The A330-200 usually has 250-290 seats, the A330-300 - 280-340. In a dense charter configuration the A330-300 can have up to 440 seats.

Each airline has its own cabin layout, so there's no single answer. The basic A330-300 configuration is designed for roughly 280-300 seats in a three-class layout, but it all depends on how much business, premium economy, and economy the customer orders. For example, long-haul flights usually have business and economy, while charter flights are pure economy in a tight configuration.

The A330-200 is slightly smaller in capacity and usually gets 240-270 seats, the A330-300 is bigger - from 280 and up. But if an airline decides to cram the maximum number of seats into an A330-300 without proper aisles, there can be 440 seats, though that's already extreme for a charter.

So check the specific flight before booking - Turkish Airways, as you can see, had 289 seats, but others might have completely different numbers.

You're absolutely right that it all depends on the airline. I have a friend who works as a flight attendant, and she was telling me that even within the same company, different planes can have different seating configurations. Usually the A330-300 really does have 280-340 seats, but Turkish Airways with their 289 is the classic setup for international flights. Charter companies though, they can cram in like 400+ when they need to haul tourists on the cheap.

The Airbus A330 in its base configuration holds around 280-300 passengers, but honestly it's way more complicated than that. Airlines customize their cabins however they want - some add more business class, some skimp on seat width and cram in like 400 people. Even within the same airline different aircraft can be totally different, because they update interiors in waves or pick up used planes that already have their own layout.

I flew Turkish Airlines last year on an A330-300 and counted 260 seats in economy class plus business up front 🛫 But I agree with the guys - it all depends on the specific airline's configuration, so there's no universal answer.
