Pros: Full F dinner service ex-SIN which is generally good, SQ's Indian main courses are a strong point.

Far more personalised service than J, crew will be very active as the flight isn't a sleeper service - good if you want to chat with the crew and enjoy a few (or many) drinks.

Suites is a huge difference from J hard product wise and the upgrade will be far more worthwhile than upgrading to the standard F product.

Cons: Short flight duration means no PJs or amenity kit.
