A while ago I was supposed to fly from Istanbul to Milan-Bergamo with Pegasus, but was refused boarding due to misinformation on travel documentation IATA's Italian government sources supplied for a short while (it's been corrected since, when I alerted my IATA contact of the incident).

The thing is, I called the border police at Bergamo, who sent a clearance via SITA Telex to the Pegasus supervisors at the transfer desk that I could fly. However, although the gate agent was made aware of it, he refused to acknowledge it or to speak to the Italian border police, and nonchalantly (and sadistically - he was smirking at me) denied me boarding.

The fact that the Italians sent a clearance to Pegasus before departure saying I could fly makes me think Pegasus made an error, and that I should therefore be eligible for compensation, as I had to wait 24 hours for the flight to Zurich I was re-booked onto.

Am I eligible for compensation? If so, how much and how do I go about applying for it?

**UPDATE:** Pegasus ended up giving me PegasusPlus flight points worth the amount I had to spend on food, accommodation and public transport during the extra day in Istanbul. As I was re-booked for free (because the SITA Telex message from the Italian border police made the supervisors realise that the Timatic error was indeed an error), that's definitely good enough for me.

**UPDATE 2** Turkey has introduced regulations influenced by EC261, meaning EC261 compensation applies even when departing from outside EU/Schengen.
As such I was able to retroactively claim €400 for the incorrect denied boarding
