I combined all different citations and put their titles on a citation list. Also used a table in PL to show how many citations come from ISI and how many from google, and how many total. I got passed on 140 with no RFE.
wait until your 行程确定 then book. If you book award ticket now and need to change later, you still need to find available saver award ticket after 行程确定, so why bother now and pay $100 change fee?
