What is the difference between an Airbus A320-100 Or Airbus A320-200?

The difference is the seating size and arrangement. Also, planes that are different 'numbers' have different load capacities, flight ranges. For example the A320-200 can hold 150 passengers and can go up to 2900 nm(nautical miles). The -100 series couldn't do so much. In fact, only 21 were actually made of the -100 series. Cheers!  more
