I just put my second second itinerary to Australia/NZ on hold, and I need recommendations from people who've flown the products before, since I've never flown any international business class, as we can only fly one of these. I've booked my wife and me on the following for essentially the same dates: 1. Depart on United EWR-LHR, then Singapore LHR-SIN-SYD; Return Singapore AKL-SIN-LHR, then United LHR-EWR 2. Depart Delta JFK-LAX, Virgin Australia LAX-BNE-SYD; Return Virgin Australia SYD-LAX, Delta LAX-JFK Other info if you decide to weigh in. The Singapore itinerary gets to SYD 8 hrs later than the Delta one, and also leaves one day earlier. Total extra time on the ground via the Delta itinerary, about 24-36 hrs. Thank you in advance for all advice.
