Can you book multiple flights on the same day?
Example   if flying from Syracuse to Phoenix, if cheaper to book seperate  like  book a flight from Syracuse to JFK, then book a flight from JFK to LAX,  then book a flight from LAX to Phoenix.

Yes,  you can book as many flights as you wish, and plan your own trip.  Just  remember that if you miss a leg of your trip, the airline is not  obligated to put you on another plane.

Well 9 times out  of 10 its more expensive but if its cheaper go for it. Keep in mind  that you will then have to do that for the way back.

You  can, but you should heed the advice of dances-with-unicorns1955.  When  you book each leg separately, each carrier's obligation ends when they  get you to the destination you have booked with them.    You can reduce your risk in two ways.  First, pay for a class of ticket  that gives you flexibility to transfer it to another flight.  My normal  carrier offers a discount ticket that can be transferred for an extra  charge.  If something goes wrong, there is still an option to change.   This ticket is more expensive than the absolutely cheapest discount  fares, but you cannot transfer them.  Second, you can take out travel insurance.  If you do this, be sure to  check the details.  I recently travelled overseas, and covered the risk  with insurance, or so I thought.  I organized a side trip, and the  return flight was delayed.  The insurer denied the claim because I had  not left a minimum of six hours between the scheduled arrival of the  first flight and scheduled departure of the second flight.    Clearly all this adds to the total cost, and you might find that they  then exceed the cheapest single booking price!

Of  course you can. Might not be the cheapest, but you  may end up with a  lot of problems: 1) miss a  connection and the airline have absolutely NO obligation to  put you on another flight, unless you pay for it 2)Luggage:   you HAVE TO check your luggage EACH time (which means you  have to go to baggage claims, wait for the carousel which may take 30  minutes or more easily at JFK, schlepping your luggage from another  terminal to another, etc, etc.,..) 3)You HAVE TO go thru security at each airport  Is it worth it???? Don't think so !!!
