All good things must come to an end. After 5 cities (comprising 4 flights, 1 train ride and 3 bus rides), it was time to go home. What better way to come home than on Singapore Airlines. Singapore Airlines operates 2 daily flights to and from San Francisco i.e. SQ2/1 (SIN-HKG-SFO) and SQ16/15 (SIN-ICN-SFO). My initial intention was to travel on SQ1 with a short stopover in Hong Kong for one last round of good food before returning home. However, I was not able to get 2 First Class tickets on SQ1. Therefore, I had to settle with SQ15.
