Cons: Flight was delayed by 5.5(!) hours, which made me almost loosing my international connection. Ground crew was mostly unhelpful and even rude in some cases, dismissing any responsible. An helpful manager eventually intervened only at the last minute, when they were finally convinced that I will never make it on time unless they make some special arrangements (which they made greatly, so i wished they did it in advance and save me a lot of aggravation!).
I suffered such delays in most other flights i had with this airline, but this one had the most critical effect.
