There are actually 9 guys who have come from KA to EK. One left to go to Airbus, the other 8 are still here. One has left from EK to go to KA....
Not sure if that tells you anything. One of the 8 is a good friend...money def better in KA, though rostering is boring with lots of time away in crap hotels in China and Taiwan. EK work more hours less pay but better variety. There is also the frieghter option with KA but that is completely different again.
