In addition to any other special offer available, you can always benefit from a discount on Emirates flights via “cashback” from www.quidco.com.
The current rate of cashback is 2% for Economy Class and 2.5% for Business/First Class. That’s £10 on a £500 flight, so while it’s not the greatest saving ever, it is worth doing.
Meanwhile Topcashback offers a less impressive 1.31% Emirates cashback on all flights.
Please note that you will need a UK bank account to claim cashback from Quidco. If you don’t have one, using a bank account of friends or family is your best option here
