I don't understand this. I logged on to their website. I couldn't read the first few codes but eventually found one that I could use. I keyed in my outward dates and checked the next week just to see if the prices were different. I then keyed in my return dates and I was immediately thrown back to the security code screen. Not only that but the pop up screen said that I need to accept the terms and conditions (again) which I already had at the beginning of the process. When I tried to do this I was then thrown back to the original screen to start the process all over again. Why should I have to start all over again. To be honest I just gave up.
