I'm new at booking award travel and have a question that probably seems stupid to experienced users here. I think I know the answers but I want to make sure before doing something I might regret. I am use to always booking paid round trip tickets so I offer the following. I finally earned enough miles to take my annual trip to China in FC. My question is - I notice that the availability of award travel tickets varies every few days. Sometimes I can find the right ticket to get there but at that particular time there isn't anything available during the time frame I have to return. Sometimes it works the other way around. Question #1 - Is there any harm or reason why I cant go ahead and book a one way award ticket to China on one day and then book the return at a later date or the other way around? #2 - Lets say I use award travel to book a flight from stl-ord-pek-csx on 10-09-12 but later find out that date isn't going to work. Am I only allowed to change that ticket to another date with the same exact routing or can I change it later to something different? I assume some type of award travel must be available on a day you want to change to. What is the typical cost to make changes once you book award travel for international flights? Thanks for any info that can be provided.
