Vietnam Airlines was fine. Decent service, decent food, cheapest flight available (paid about SGD600 for a December ticket).. But worst transit experience ever. The airport at Ho Chi Minh City was probably the worst I've ever been to. Unclear directions/signage, messy layout - everything you fear about when taking a transit flight. At least the transfer counter staff was helpful. Don't think I will ever use Vietnam airlines again unless it is really REALLY cheap. 

My two meals from SIN to SGN, then SGN to ICN. 

Anyway, I made it to Korea safely! Here are some pictures of my first few days in Korea:
