Booked 747 in first and now have A380!
I think I just became one very lucky person. I booked a trip to CPT next year from IAD stopping in FRA and JNB in first using miles. Well, I was just taking a look at the reservation and noticed that my 82H seat had been changed to 1D and that the plane is now an A380.
I'm not sure if Lufthansa will be doing the same as Singapore and not let you get these seats with miles but it looks like I did it.
Content happy smile on face now.
