Tried a couple of the flights with and without the code and both times prices were identical. Yes it had the yellow dot on the in/out bound flights to indicate that the code would apply. Scam!
Just thought I’d come back and check. Link you have posted now seems to work for me but price can be beaten using Skyscanner. Thanks though op (y)
Still a discount nevertheless!
Base fare exluding taxes. Not great. Cold.
Definitely works.. just booked and saved 116 pounds :)
