I'm looking at options for a trip BOI-KOA next Jan. (two of us). Of course, there are no Bus/First Saver awards available for two on the day we need to leave. But, there are coach saver awards available BOI-SFO (CR7)-SFO-KOA (753). 1.If I book this itinerary in coach ("X") should I do it online and then call CS and ask to be W/L for Bus/First ("I") on both legs? 2. Will CS charge me the Bus/First price of 40K at that time or after (or if) I clear the W/L? 3. What happens if the first leg, BOI-SFO clears but the SFO-KOA doesn't? Or vice versa? Will I have the option of refusing the change to Bus/First on the one leg and flying both legs in coach (X)? For the coach fare of 22.5K? 4. Where would this W/L rank vs those using U/G instruments? Thx!
