Singapore Airlines never fails to disappoint, what sets them out from the rest is the service is always consistent. Excellent regional Business Class product onboard my short SIN-CGK sector. Used the Book the Cook option and got the lobster I ordered.
SQ ; is not as excellent as stated. Yes staff is friendly but and aircrafts relatively new BUT- they fall short from being best: many aircrafts dont have the advertised full flat but older seating cofigeration in business, food is at best mediocre in business, also aircrafts with thr full flat look used ç and often even dirty) inside. eg Swiss business , or new ANA business surpasses SQ. Austrian, sometimes LH, ANA, Cathay give you a better overall experience and nicer to enjoy. I would call SQ 4 star bur NOT 5
I still think SQ is the best. Service is amazing, they only advertise their full flat bed on long-haul plane (B773ER and A380) which are deploy to main EU destinations. Tokyo, JFK and OZ. Food-wise, you can “book the cook” if you know you will not like the in-flight selection.
Austrian and LH are better? You must have not been flying with SQ for a while. CX New J maybe is better (haven’t tried it), but I don’t think ANA new J is as good as SQ new J, nor does Swiss.
