Is SQ First Class worth the extra miles versus Business?
I am using miles to fly from Boston to DPS with a layover in SIN. Can anyone advise whether flying in F is worth the additional 30K miles? (140K versus 110K, thru Delta). I am 6'3" (190cm) so having plenty of room is important to me. Also, has anyone noted any differences between the JFK-FRA-SIN and EWR-AMS-SIN routes? I will be flying in December.
Thanks
