Guess as many of the operators of aircraft in the A320 family as you can.
. The Airline must have 10 or more A320 aircraft to qualify for this list
. This Quiz includes the A318,A319,A320,A321 and all Neo variants
Great quiz, but you gotta put some more effort into the type ins. PIA should work for Pakistan International Airlines for example. And many of the "Airlines, Airways" are unnecessary, like in Austrian, SWISS, Spirit.
