Austrian Airlines' Airbus A320-214 (320) operates in a two class configuratuon with 28 Business Class seats and 132 Economy Class seats and is primarily used on short- and medium-haul flights.
Business Class is made by covering the middle seats in the first few rows of the aircraft. Meaning, the configuration of this aircraft varies. The seat pitch and width remains the same, however, you are given a bit more space with the middle seat being blocked out.
