It is used to be that in order to book a flight one will go to your local travel agent. The travel agent will then take down the details of your tour, and will then research their system and proffer you certain deals.  You will have to take their word for it that this was the best deal and the only way to try and get a better one was to go to another travel agent and ask them to do the same thing. As you can see this was a very time intensive task and information was all controlled by the travel agents. Very often people will take a deal that was not nearly as good as it could have been, just because they did not have the time, or the inclination to go in research of another few agents to compare the charge to. It also meant that travel agents were open to abuse the system as there was no real transparency.  Airlines and travel companies could, and will offer travel agents kick-backs to push their deals to customers.   

Even though, things have truly changed now, people are now capable to go online and search for, compare and book their own flights and tours. This has literally made t

By using the internet people are capable to very quickly (literally a few minutes) compare many flight and hotel options and prices. The best thing to do is to use a travel comparison engine that compares multiple airlines and suppliers all at once. Then you can quickly find out who is the cheapest. Another clever thing is that you can immediately book and pay for the journey, while online.  The ticket would then be sent to you via email.  All of this can literally take a few minutes.

So, basically booking a cheap flight online permits you to rapidly and easily compare multiple providers and then pay for and receive the ticket via email within few minutes.
