Flight explained
How many passengers fit in an Airbus A320?
How travel classes and seat pitch change the capacity of the same aircraft.
The short answer
The classic Airbus A320 typically carries around 150-180 passengers. The A320neo has a certified maximum capacity in a dense configuration of up to 194 seats, but a specific number is determined by the airline.
What determines the number of seats in the Airbus A320
Business class with increased seat pitch, free middle seat or separate seats reduces overall capacity. Quantity is also affected by kitchens, toilets, emergency exits, and evacuation requirements.
Therefore, the name of the model in the ticket does not guarantee the same salon. The scheme of places is better to look at on the website of the carrier for a particular flight.
