I have been trying to check in for a flight which leaves the US late tonight heading back to the UK. For many hours I've been getting the same error message:
Sorry, we are unable to offer you Online Check-in for this flight.
We recommend that you review the status of your booking.
To check in and receive your boarding pass, please proceed to the airport.
Being a slow morning at work

, I thought I'd call BA and see what the problem is. Spoke to a really helpful bloke who called the web 'support' team.
They have advised that this message often occurs when the local airport doesn't "release" the flight for OLCI. This can be for a variety of reasons, none of which they are privvy to. It is only the airport that can open the flight for OLCI...does anyone have an insight into what these reasons could be? (only for my curiosity more than anything

).
