Good point jtr. CX pilot conditions are static, EK's are dynamic.
With any job you need to look at the macro economics of the company's situation if you are looking to the future. EK is the airline of an energetic government who are developing their country with vast strategic aims. CX is tied to a HKG government that has no power over the development of aviation in Hong Kong, either because of entrenched interests or mainland control.
One point that is often overlooked when searching for a pilots job is, what is the perceived position of a pilot in that company, and that country. For instance, when in Taiwan recently and a parent wanted to take a photo of the captain next to his four year old son, the comment from my new to CX trainee was "This is amazing, they treat us with such respect, this does not happen in my country." A true Borat moment.
Also, what is the perceived position of a pilot in the company? In companies where the Director of Flight Operations is not a pilot, you may find that pilots are treated as low grade labour, and our professionalism is either mis-understood or deliberately undervalued.
So many things to consider.
