On the 777 the suitable airports around his position would have been
Ho chi minh, Kuantan, KL, Subang, Langkawi, Penang, Johor Bahru, Sing etc some of those would have been closed at 2 am.
Others like Kota Bahru, Terengganu, Ipoh, Alor setar, etc are a little short for a 777 except for a grave and imminent emergency.
