Answer 1

look up their fleet?

Answer 2

There is no way to find out.  Nobody knows besides the dispatcher, and she may change assignments at any time.

And if you show very much curiosity about this at all, you will feel a big, strong hand on your shoulder, along with the words "We're from the Department of Homeland Security, and we're here to help you."

So it's best not to ask.

Answer 3

You want to know which exact aircraft will take you somewhere?  Like Avio says, it's up to dispatch, and they often change at the last minute.  For instance, if you are in an airline's hub, and they have a mechanical problem on the ac chosen for your flight, they will often switch to another one so your flight can leave on time.  Then, the original plane gets worked on my maintenance, and perhaps does a later flight.  

So, the big question is, why do you want to know this?  Perhaps we can give you a better answer if you tell us why you want to know.  Thanks.
