Interestingly enough, in my stalking research I found Armagan has indeed bought tickets for Malaysia, and he has booked 4 hotel rooms in the Hilton Kuala Lumpur hotel, and the reservations are extended for a full week. I suspected something strange, then found another plane tickets from Kuala Lumpur to Krakow. Interestingly, I didn't find anything else plane-related, but I did find a whole cabin was bought at discount train tickets to Lyon 3 weeks later after the tickets to Poland, but I haven't found the hotel reservations yet.
There is one single plane ticket from Lisbon to Ankara, for a month after the train tickets, but the last name is Yavus, so it may not be our Armagan.
Further investigation is required.
