As much as i would like to take up this option, as much my experience with EK tells me to be very careful.
The company demonstrates in an almost daily rhythm that they change goalposts as faster as their clerks get to Costas every morning. They will initially offer T&Cs that may attract enough pilots. But we all know, that within three months they will adapt the goodies to make them suit their needs & greeds and the poor sods that signed up for two years will be stuck with rapidly deteriorating conditions.
Trust has gone for a very, very long time. No one believes anything no more what EK says or even signs. They will reap what they saw.
