I want to use my Frequent Flyer Miles with United to fly from LAX to BKK.
Never done this before so a couple of questions.

United has a flight from LAX to BKK. So must I use the FF miles on United or can I choose to fly on Singapore or Thai, which are Star Alliance members?

I have the 60,000 miles required for a ticket to SE Asia. Can I book several segments for the 60,000 miles. Say LAX to SIN, SIN to MNL, MNL to BBK and BKK to LAX. Must they all be on the same airline, or can I fly Singapore from LAX to MNL and then Thai from MNL to BKK and then BKK to LAX.

Finally, can I use FF miles to upgrade on Thai from Economy to Deluxe Economy? Anyone know how many FF miles are required for an upgrade?

OK, three questions. Some answers please...
