It seems the BA App has perhaps taken a holiday. My upcoming flights have all disappeared, and it’s refusing to recognise any input reservations. I noticed that no “it’s time to check-in” email arrived earlier, but just had time to sit down with it. Seems completely defunct from the check-in standpoint…BA.com happily took my record locator and checked me in. Strange, but not exactly unexpected. Will be very annoying if all my future PNR’s need to be entered again.
