The best prices for tickets can be found directly on the airline's website flyplay.com. The lowest prices can be bought about 2-3 months before departure, but with more advance notice the price tends to increase. However, the airline has been in operation for a relatively short period of time, so it is possible that pricing policies will change gradually, for example on routes where there is already competition.
