Just as another data point
I have been waiting nearly a week for a straightforward redemption on EK to be ticketed. Three flights, all in the same class with no stopover. New booking, so no changes to complicate things.
I called up on Saturday to book. I had the flights booked but was told they could not price it as the currency they required could only be used on weekdays, so told to call back on the Monday.
I called on Monday and was given a quote (in Australian dollars - the currency that does not work on weekends!) and my card was debited, but was told they could not calculate the points required without specialist help - they would call me back. it is so difficult to look at a redemption table, I know...
I called again on Tuesday to ask whether they could now calculate the points required. After ages on hold and the involvement of the specialist team, I was told it was 89,800 points which I had known all along. Unusually the points were deducted immediately. They also said they would recalculate the fees to make sure I had paid the correct amount - and concluded that i had. I was told it would be ticketed within 24 hours.
On Wednesday, more than 24 hours later, I called again to find out where the ticket was. After much investigation and holding, they told me that ticketing had failed because the amount of fees I had paid did not match what had been recorded against the booking, They recalculated the fees, found that I had paid the right amount and they had entered the wrong amount against the booking. They promised this had been fixed and the ticket would now issue within 24 hours.
Now it's Friday. Two days later, still no ticket. I will have to call again.
Really, how hard can this be?
