Flights are on a single AY ticket (105..). Looks like IB3172 is usually on time, but the connection still feels a bit risky. I don't mind spending the night in London, but who should I contact for the new flight and a hotel booking at LHR in case I miss the connecting flight? And who would be responsible for them, IB or AY?
