No, they have no such compass on board, Turks, especially those that fly THY (as opposed to charters) are NOT a religious lot. Amazing the amount of conjecture some people are coming up with here. GU has it pegged, except for the fact that the primary language used is Turkish and that if things go wrong their CS is not that hot, flying TK is just like flying LH, OS, (shudder ) AF, or any other European carrier. One should also keep in mind that TK is now perhaps the fifth or sixth largest carrier in Europe and is larger for example than LOT and Spanair COMBINED (and will be even 30% larger in two years time) I am not a big fan of TK, but its faults do not lie in the fact that the main religion in Turkey is Islam, considering the fact that today was the first day of Ramadan and that every restaurant I passed today, during the day, was doing business as usual, this should tell you how seriously many Turks take the whole thing (anecdotally, for the first day few days of Ramadan a lot of bars do close down, business is bad, most are open by the end of the first week at which point business is down 30%, by the end of Ramadan, business is usually UP by 5-10% by the very end).
