DESKE.....I know some think CAL is the end of the line.....but I think it stands for
EXTENDED LAY OVER
It was their way to build bases where people could live and cut the company's costs. The benefit to the pilots were to allow them to be home more and to be in Taiwan less.
I know they did start a few places and I expect that they moved it to F/Os. Previously it was just Captains that they built bases outside of TPE for.
