Hi - does anyone know how this works? I’ve bought PE AKl-LAX upgraded to Business using points for flights in August and September. My daughter wants to join me, and I can see X class avail for the return on EF. Is it possible to buy the companion fare one way only? And if I’m not travelling in the same cabin, can she still travel on one of those fares? The info online is scant and a bit confusing. Would love to ask the call centre but…ya know..
