Hi.

I have been searching the threads and have not yet found an answer to this. If someone has it and get provide it...thanks. In the meantime I will keep looking.

I have an RTW biz class paid fare, booked through US that has an LH leg to Europe, 2 SQ legs from LHR to SIN and then two days later to SYD and then United leg from SYD to SFO. Is there any way to upgrade individual legs using cash or points? For example I have Delta points...can I use them on SQ? I have lots of US points. I have Virgin points as well. Also I can transfer Starwood points to any airline.

I will keep looking and post what I find in terms of answering these questions. Eager to see how the new United biz class is...and VERY EXCITED to be flying the 380 from LHR - SIN!
