I am thinking of booking LHR-IST-ORD in Business, arriving 17.15 at IST and departing at 14.15 the next day. If I stay in the Yotel airside, what lounge access will I have? I have been caught out before on Asiana where I was not allowed in the lounge at KUL on arrival even though I was not leaving the airport. I am LH Gold if that makes any difference.
