Tehran-Zahedan Economy. I am a regular traveller on this route probably flying to and from Zahedan from tehran about 12 times a year - an expert in terms of seating on these old A300 Fokker 100 and B727 aircraft. Always ask for seat by the exit door. You will otherwise experience severe cases of cramp and discomfort after each flight. The food on these flights normally comprises a cold platter two filled rolls a chocolate biscuit and an orange drink! A truly sad airline and even a sadder experience if you ever get to fly on one of these planes.
