Turkish Airlines' BOD decided to add a total of five A330-300 type aircraft to its fleet. Two planes will be delivered for certain in 2014, while the three remaining orders could be placed in 2015 and 2016. 
Recall that the company had announced in the beginning of October that it was planning to add a total of 15 A330-300 type aircraft to its fleet between 2014 and 2016. However, as far as we understand the current purchase announcement is separate from the earlier one. 
We re-iterate our view that these steps are in line with the company's plan of increasing its network and having a greater presence in long-haul flights. The structure of the fleet is would of course have to adjust to this strategy (i.e. a greater number of wide body aircraft in the fleet).
