I have discovered that buying a fix dated ticket is not as convenient and could be costly ( if you have to make changes to the dates/destinations on your ticket).
In my experience, and based on the kind of travelling I do ( total flexibility- no time/country constrain), I am better off buying a one way ticket via the internet to my first destination.
The trip I made to Europe was with a return air ticket had cost me more that I anticipated whereas my friends who travelled with me only bought a one way ticket via the internet. In the end, I added iup the cost, the cost of my ticket was more than their as I had to make various changes to my ticket and each change costs !
