Fuel surcharge on United flights
I googled and did a lot of searches here, but I can't find the answer to my question. Does Singapore Airline impose fuel surcharge on award tickets for international United flight originated in US? I know it doesn't for US domestic. For example, if I want to book an award ticket using KrisFlyer miles for a United flight from SFO to SIN or to HKG, do I have to pay fuel surcharge?
