Iain,
If you read through recent posts you will see that EK are unlikely to respond to your e-mail application in the usual timeframe as the recruitment process appears to be on hold indefinately.
I work with several girls whose applications are on hold and they are climbing the walls waiting for some news!
My advice is to put it on the backburner and not hassle them for a response as this may not go down too well. The general concensus is that you will be waiting a WHILE...
