The least i would accept is a one way upgrade. The only reason i pay much more and fly C is for the comfort of the seat. If they can't provide that then what is the point!

Don't settle for a silly diary. Write to them again and again. Insist on it being escalated to a manager! I think airlines now days have a basic format for all type of complaints. Where they just click a mouse button and out goes a standard template letter to the customer! Even with KLM, it did not matter what you complained about you would always get the same template back. It was very annoying... like complaining to a computer.

Personally i would be very angry if i did not get anything!

On a recent Air New Zealand flight in Y my seat would not stay reclined and even though I just pointed it out to the Purser, it was just for his information so it could be fixed for the next passenger he brought me a bottle of Vive Clequet Champange (i think thats how you spell it) and a bottle of their finest wine on board from Biz class.
