One reason people love flying First Class (aka Royal First) on Thai Airways out of Bangkok is access to the Royal Orchid Spa where First Class passengers can get a 60-minute full body massage. But you need to be departing on a same-day Thai-operated flight in First Class to get this benefit.
According to this promotional article on Thai Airways Australia, Royal First Class is offered to the following destinations:
- Hong Kong (some flights)
- Tokyo (some flights)
Useful to know if you want that hour-long massage!
