As some of you have correctly observed, the real annoyance is that it will not let me do OLCI unless I keep on entering my details each time. So unless I do this it's no seat selection for me. If not for this, I would just ignore it. This has only started happening to me recently and I have a British passport, so I don't know what has happened to upset it. I guess it's the Customer Service route for me if it persists.
