Hi all, I booked flights for US-FCO-US roundtrip using DL miles but flights keep getting canceled. So now I used UA miles to book an LH/LH flight for US-FCO (77k miles per person), but the return flight is still not booked because I have no more UA miles. I have lots of MR and UR points that can be transferred once it gets closer to travel date, also have about 120k DL miles, 200k BA miles. What's the best way to book a return flight? I looked at NH miles but surcharge is too high for most aspirational carriers. Right now I'm just looking at AC miles to fly back, they're 70k miles per person. I have some flexibility too to fly out of other Italian cities rather than FCO. Any recommendations welcome!
