Perhaps more regular longhaul travellers in Business class than myself could point out things that are still missing from Singapore Airline flights as most of the world emerges from Covid. As far as I can make out the following are still missing.
1. No hot towel service
2. No onboard literature such as newspapers nor printed menus
3. Very hit or miss pre meal service drinks
4. No warm nuts with drinks
5. Compulsory wearing of face masks.

Is that all?
