Even though we are registered with BA and our profile is up to date, on our flight this week it says that information is missing. I added the passport information that was not there (but it is in our profile), the only other empty field is this question "where are you staying the first night in t he US" It doesn't apply because we're flying to London, but I added our home address in the US, since it gives a missing information notice if I don't put anything. We still get a message that there is something missing even though all fields are complete.

Any idea what the problem is? I called BA and they just said to check in at the airport.
