What is the cheapest international airline?
That depends greatly on to where and from where you are flying. Some of the Airlines that are known to be very low cost are PIA, BIMAN, Korean Airlines, Cathay, Royal Thai, and many others. The currency exchange rates have a large effect on the airlines prices. If you want a bargain, check aound. During the asain money crisis, Korean Air lines prices were well below the competition throughout asia. Bear in mind that the cleanliness, food and service standards of many bargain airlines do not compare favorably with American and European airlines. I have always found Cathay and Korean Airlines to have excellent service. The cleanliness and service of PIA and BIMAN I found to be unacceptable, I would not use their airline again. Its worth the extra few dollars to fly a more reputable airline.
