Can you link two itineraries - one paid, one miles
I am holding award tickets DFW-LHR, but am trying to get the family to ATH. Does anyone know if there is a way to book the LHR-ATH r/t if purchased through AA or BA and link the reservations? I am assuming that BA won't open up the award inventory I need, and as a result will need to buy the onward leg.
What I am specifically trying to do is find a way to be protected on a connection at LHR in either direction if there is a flight delay/cancellation into LHR in either direction. I realize that worse case I should build a day buffer in London each direction, but it would be nice to not have to do that.
