Speaking purely personally I just cannot be bothered to complain or worry about equipment changes any more - I admit it, I have been beaten into submission by EK's lack of concern or remorse for pretty much anything that happens. The only time they are proactive is if it will help them to avoid a problem by being so - IME they will not be proactive to help to keep a client happy because ultimately that is not part of their business plan or model. Until they have trouble filling their planes why should they bother goes the commercial argument. Thanks to Khalid's recent post I now know that a flight from Rome next month in F with my wife will not be on a 380 but this is not the first time I have been bumped from a 380 to something else and it will surely not be the last ... all one can hope for is that you don't end up on a dreaded 330 or a two class 777 when you get tossed from your anticipated F suite with bar and showers (accompanied by a singular lack of apology). Focus on the positives such as even with delays travelling with EK is quicker than it was by sailing ship 100 years ago and it is also a statistically very safe airline. My advice is to release these annoyances and enjoy the very next moment as if nothing had happened.
