Tried to search, but surprise!

, it didn't work. Anyway--any insight on how (or if!) you can ticket your flight so that you would have the option to fly into/out of any of the three airports (or either MIA or FLL)? I'm not sure if this is standard for airlines that fly into more than one of the airports, or what.
Any experiences to share from other FTers who have done this?
Pardon my ignorance!

and thanks in advance!
