Is it possible to stop an award ticket with a stop over too? I called UA yesterday and the agent told me that it can be done, she said "just follow the instructions." Well, I tried, I don't know how and couldn't find any instruction. I want to book SEA-SFO-HNL with a stop over in SFO. BTW, how long can I stay at SFO? I remeber someone said 24 hours, is it true? Any suggestions would be greatly appreciated. Thanks in advance.
