Some airlines will not accept vouchers for internet ticket purchases. Delta won't even let you use their electronic vouchers this way.
But it is more relaxing to use the internet to figure out what flights are available. THen if you finally do call an agent to actually make the reservation, you have narrowed down the choices to two or three flights.
<big>Caution:</big> If you don't know how to "print screen" or otherwise get a paper printout of your transaction instantly right at your computer, you really should not be booking or buying or ordering anything on the internet. There have been some isolated instances where the confirmation for the non-refundable reservation from the airline arriving in the mail a few days later had the wrong dates and times.
If you need later customer service, for example if they cancelled a flight, you practically must use live help over the phone.

Airline reservationists must have a hard time when their popular flights are sold out, spending long hours with customers who don't finally buy!
My typical conversation over the phone before they invented the internet...
Me: I would like to book a trip from Boston to Orlando on November 21.
(clickity tappity tap tap of fingers on computer keyboard)
Agent: Those flights are sold out. Do you have an alternate date?
Me: November 22
(click tap tappity tap)
Agent: Those flights are sold out. Do you have an alternate date?
and so on back and forth
Half an hour later both I and the agent are getting frustrated and exasperated.
