Although not being a EU member Turkey is a member of JAA,therefore all airlines in Turkey including the Pegasus meets the same standards as a Dutch airline in safety wise.The civil aviaiton authorities of member countries are routinly inspects all JAA member airlines and their aircraft if they meet and keep the safety standarts mandated by the JAR's.Pegasus is a company which was founded by the AirLingus in late 80's, later bought completely by the Turkish partner and flying tourist charters to Europe as well as operating some wet lease operations for foreign carriers.During my work period we flew as wet lease for the following operators(AirAlgerie,Khalifa Air,AirOne,AirSofia, Air2000,AirAstana,etc)
Pegasus operates 22 B737 type aircraft most of them the brand new -800 series(some with blended winglets).I don't know the latest number of AC
because they were returning the 737-400's during the time I left the company this new year.
Pegasus airlines is the "recomended" and certified by the Boeing company to eastern Europe and middle east region for 737 type rating.The company has trained 737 pilots for AirAlgerie,AirAstana, as well as some Eastern Eurepean pilots.During the time when I left there were pilots for a Norwegian airline which I can't remember now.So pilot training is also highest standarts thats why Boeing company recomends the company.
The maintenance is done by Turkish Airlines maintenance facilities which is the most modern and biggest of Eastern Europe and middle east.Our mechanic folks are also mostly ex Turkish airlines and Istanbul airlines mechanics with very much experience.The bigger maintenances are also done by AirLingus in Dublin and Lufthansa in Germany.
About what to expect from Pegasus service is depends what you expect but in my opinion Pegasus serves unnecesserily too much for a charter airline. Depending on the time of flight you probably will be served hot drinks first,then a hot meal and alcolic beverage,another hot drink after meal and the duty free. One has to keep in mind that you are not paying to ascheduled airline but this is a part of your holiday trip and the service is dictated by the travel agency not the airline itself.So you can expect as much as you are paying for the holiday package itself.Which is the cheapest compared to the other European countries.
A broken seat is never allowed to fly with apassenger seated its simply banned for that flight until repaired but if its broken during or after boardin there is not much to do for it.
About the delays if not because of a techical fault(which any airline can have one) the most usual cause is the last minute ticket sales of the tour operators.Most operators try to sell half priced tickets 1 hour to departure time if they couldn't menage to sell all the tickets for that flight and that causes a lot of delays,extensive post 9-11 security in the airports and handling services are also major causes.
So you can board any Pegasus airplane without any doubt in your minds.I am telling this because I wouldn't and(none of my pilot collegues)would accept to fly with an airplane which is not fully safe to fly,in the first place.I hope you enjoy your flight and would love to hear post flight trip report.
