I haven't flown since last October but I'm on a flight to LIN tomorrow (16th June) and my daughter is on one to AMS. Both of us unable to OLCI despite the button being there to OLCI in MMB and us also receiving an e-mail informing us OLCI is open. Trying to just gets this message:
"Sorry, we are unable to offer you Online Check-in for this flight on this occasion.To check in and receive your boarding pass, please proceed to the airport"
When my daughter flew in from AMS 13 days ago she was able to OLCI for BA at AMS but seemingly not on the return LHR-AMS. So, are BA IT systems yet again up the creek or a wider issue to do with Covid related docs checks?
