I sympathize with you too, i said "good bye" to EK almost a year a go after being a gold member for almost 6 years

Their business class desk rep changed my booking over the phone beyond th expiry of my ticket, which i didn’t realize, arrived at the airport in the limo booked by emirates with my boarding passes printed online to find out that MY BOOKING HAS BEEN CANCELED due the EK staff fault!

They forced me to buy the most expensive economy instead 900 Euros for MXP-DXB-MXP , I had no choice

I wrote to Customer Service and met the EK Area manager, but the answer was NO RECORD OF ANY MISTAKE COMITTED BY THEIR STAFF! And no record of any changes to my old booking, despite my boarding passes and my limo booking!

Now, i gave up, i asked for a refund of my unused portion of that business class ticket, they are REFUSING to refund too!

So my decision was based on many factors and am a happy customer with EY and QR now

Good bye EK
