Group of 3 traveling LAX-IST-FCO. One of us accidentally booked on the later flight (TK10) out of LAX and the other 2 are on the earlier flight (TK76) Any chance of getting our friend on the earlier flight with us when we check in? I already called and they said if we purchased another ticket, same day & same name, other flight time they would refund the the incorrect one. I wasn't trusting that though.
