Well you are still on time... did you resigned ? Withdraw you resignations if you still can and stay where you are. Nothing good coming out of EK and Dubai in the near future.. This delay is a symptom of impending problems. You have been warned. If you are unemployed or desperate..that is another story.
Not sure how bad it really is in Dubai for you, but if you have left hand seat experience you should know that my company is recruiting, it's a big european loco, from Ireland. It has a very good reputation, I promise they will treat you fairly and base you in the country of your choice.
We are not debating here whether we should join or not, our decision is made so please post relevant information or keep your opinion to yourself...
Thanks for the word of advice however.
