Singapore Airlines KrisFlyer - Help with C to F Upgrade?

I'm flying this december and I got a C class seat booked on the SFO-HKG-SIN flight..

I want to upgrade from C to F using my Krisflyer Miles, but I can't open my itinerary over the internet to use the extra 15% mileage discount. I'm dreading if I'm calling Krisflyer CS, they're going to say that they can't do anything on giving me the extra 15%..

So what should I do? or more appropriately, how can I effectively persuade SQ's CS to give me the extra 15% discount?

I called them once asking about how many miles are required, and their answer is textbook. I asked them again regarding why I can't open my itineraries online and they started to point their fingers on Silk Air..

Please help me resolve this "miniscule" problem..

Thanks in advance!

Did you book online?

No, but until recently I can still open my itinerary and I have the upgrade option available to me...

Got another question, related to topic:

Would you upgrade to F for 100K miles, or seat yourself on Row 11 seat on a 77W?

It seems to be the nicest row on all the aircraft, any different opinions?

Paying 100K to upgrade to F from Row 11 on a 77W is an effing waste of miles, imho.

Don't do it - you sleep most of the first leg and a seat in row 11 is just as comfortable.

Thanks for your input.. I've canceled my upgrade and decided to keep Row 11.. And hopefully on the way back, I can get Row 11 again.

I've never tried C in 77W, is it true that the seat pitch is much shorter than those on the A345s?

Save the 100k miles and just buy a few bottles of krug to make you whole. ;)

Couldn't agree more.. :D

I'm still wondering though whether or not the seat pitch (not width) is actually longer on the A345 than on the 77W, can anyone confirm that?
