I am going on a cruise so need to get to Hong Kong in February, 2013. I am using miles from American Express, transferred to Aeroplan to redeem one way business class seats for LAX to HKG. I already have the flight reserved for the return on Singapore Air (SIN-LAX). The best choices I found are either on ANA All Nippan Airlines which has a stopover in Tokyo or on Asiana with a stopover in Seoul. The ANA first flight is on a 777-300 and the second flight is on United on a 737-800. The Asiana flight first flight is on a 747-400 and the second flight is on a A330-300. Both are on Asiana. Which one would you go with and why? My main concern are the seats. Also, all of these flights arrive in Hong Kong at 10 or 11 pm so I have some concerns about that.
