Flying from JFK -EUROPE this summer with the wife. I am a delta Diamond Medalion but all domestic travel so international is new to me. We have never flown on the 747 or a380 so that’s something we want to do. Between LH and AF first class any recommendations on which is better overall? if we do LH it’s the a380 one way and the 748 ( nice because we get both planes), and on AF the a380 one way and the 777-300ER the other. Flying LH, we would loose the MQM for delta but it’s worh it if LH is that amazing. And is it worth it to go out of the the way ( different airline alliance) for the a380 and 747. Thank you everyone
