Big. No, it's very big! The huge size allows you to comfortably organize a large passenger flow. But there is a disadvantage behind this - you have to lay a reserve when connecting flights, otherwise there is a risk of not being on time due to waiting on the runway or long taxiing and running through endless corridors.
The worst airline flew through this Berlin company and back.Very rude staff at the check-in, on the plane.Artificial problems were created.I do not recommend anyone to fly through this company at all through Turkey!
