Cited above is my opinion posted here in November 2010 after FR decided to compete with trains on Valencia - Madrid route, with 3 daily flights in both directions. Guess what? The route will end in March. Reiterating: "carrying out some research..."

Then on the other hand CIA-BGY is, the last time I looked, the 2nd most profitable route in the whole company, and they compete against the high speed train and trains in theory in this route with 4 flights a day. I think FR have admitted sometimes they just try a route completely randomly and it sometimes is a flop and sometimes is a great surprise.
Where are the next bases or bulk of expansion going to be? Lot's of aircraft coming in the next year.
