It's perhaps no wonder that this 16-hour direct connection from LAX to Dubai hits the highest rungs of this list, what with all the fashionistas, A-listers, VIP businessmen and Hollywood locals that no doubt make the trip regularly. That said, there's no question that Emirates' first class offering is good, in fact it's nothing short of legendary -- with most A380s, A340-500s and 777s now coming complete with fully partitioned private suites, individual mini bars, flat laying mattress beds, vanity tables and even on-flight spa facilities!
