Just logged in to my husband's account to enter his Advanced Passenger Info details and noticed that his upcoming flight data has disappeared.

"My upcoming flights

We can't find any bookings for this account.
You can add a booking by entering your booking reference below.
If you have just made or added a booking, this may take a few minutes to appear in your account."

The booking has been "viewable" in the account for some time, was even there this morning. Now it has vanished. I can enter the reservation code and his surname and get the info and his Executive Club number is attached to the booking.

Is this a temporary glitch? Should I be concerned?
