If your salary is QR35K or more you can opt for QNB with their QNB First facility which allows you to use the airport lounges around the world, a faciltiy which comes in handy when travelling economy class. Also using their Master Card (credit card) gets you miles with Qatar Airways which you can use for travel. And there services in last 5 years of my being a customer has been excellent. (P.S: I dont work for or with QNB).
