Sorry, I may not have been entirely clear. My concern is only whether by booking a ticket in "first" that is cheaper than some of the "business" fares, that somehow what I am buying is not actually a seat in the business cabin. This just seems odd to me that the first class fare is cheaper than the business fare. I know on US airlines, or at least on United, it's not uncommon for a single cabin to be marketed both as "first" and "business" but I just want to be sure there is not something different on ctrip.
