wawkrk, i read your post regarding the apu that had been kaput " for weeks" with interest, FYI the apu is regarded as fairly important, which is why the MEL lists a u/s APU as a cat C item, which means the defect can only legally be carried for a maximum period of ten days, i realise you havent a clue about the maintenance of aircraft but rest assured airlines dont decide how long defects are caried, a legally binding document called the MEL does that.
Finally how anyone paying as little to fly as they do with the lo-costs can whine about a bit of missing trim or a non essential filament in the cabin being u/s is beyond me
