I am currently looking to fly from IAD to DPS with 2 stops. One in SFO and one in SIN. When I try to book economy and request the upgrade it says 40 points each way. Does this mean for the total trip it will use 80 plus points or is it 40 points total? When I do a mock check out it says Total (due later) is 40 PlusPoints. FYI we are doing a one way flight to DPS. From there we will hop around asia to BKK, SGN and then HND.

I'm planning my 40th birthday trip in June so a group of my friends are coming with me and I would like to upgrade most of them to business if possible. Any tricks or tips will be greatly appreciated. Thank you.
