Urgent help needed- IB flight booked through BA can’t check in!
I booked return flight LHR-MAD-LHR through BA app and am flying on IB metal. Tried OLCI for the return leg MAD-LHR but BA/IB app, BA/IB website all throw up error messages.
I could wait until I arrive in Madrid (currently in HKG) and try checking in at MAD but if the CX to MAD leg is delayed then I fear missing the flight and having to pay for another one (separate tickets)
advice please?
