I don't get it with the new restriction on only 2 same layovers a month...the bidding system does not work unless you are pretty high up the totem pole or its your top or 2nd top bidding month.
The rest of the months you get sent all over the EK network at the whims and fancies of their ops requirement. And when they roster you for 90 hours without fail, there are a lot of opportunities for other destinations to be included.
Just another one of the stupid things to screw up our lives.
