Just completed a booking for August return Dub-Fao. While there is lots of availability showing I am not sure it is all real. The 1st booking I made failed and a quick check on EF showed no availability for the flights I had picked. 2nd booking with different flights worked and appeared on my AC account but still with the message that no online changes are possible and advising chat or a phone call.

Definitely a much better website than the previous version.
