If you have Singapore Airlines miles first class awards turn out to be easy to book — on their old 777 product from Los Angeles, and flying Airbus A380s all over the world. Provided of course that the A380 doesn’t touch the U.S. (New York JFK – Frankfurt) and isn’t their newest product.
And Singapore Airlines business class awards are frequently very available too and that’s true even on U.S. routes, especially from Houston and Los Angeles.
