I was due to travel GLA - BKK last week before the plane went tech and was unable to fly. I am Gold with many miles so I have upgraded at check in but only GLA - DBX due to availability.

Emirates kept us waiting nearly 10 hours before finally cancelling the flight and providing overnight accomodation. The whole process was a shambles and their customer service department did not care.

We arrived back at the airport the following day and they had fixed the plane overnight and we departed to DBX with me in business class.

Over a week later I have still not been deducted the 25000 miles for my upgrade.

My question is should I still complain to Emirates and see if any form of compensation is going to be provided for my inconvenience and delay, or should I just keep my mouth shut and hopefully get away with the 25000 miles?

I might add that I have never really been successful when I have complained in the past.

Your thoughts please
