I know and have flown/experienced SQ on an Intl level.
What is, if any difference in say HKG-SIN, BKK-SIN, PVG-SIN, ICN-SIN, or HND-SIN?
Is it still the same amazing 5star service? If so any difference, changes, things I should know? I'l be in Asia for my birthday before heading to LHR for the Olympics with my brother who got my tickets to several events for our birthday.
