Actually, the volume of traffic from Pakistan to India is significantly higher than the number of passengers flying from India to Pakistan. This has become more pronounced since the Indian Airlines hijacking in December 1999. Indian tourists, especially those Indians who still have family across the border (like my own parents) are keeping away in droves, and of course, technically the Pakistani government does not allow open trade with India. I have not heard of any Indian involvement or collusion in any Pakistani airline hijacking, so I don't know where Airmale is getting his phobias from, unless he means that he'd rather not fly an Indian carrier for other reasons (bad connections, spotty service, etc etc - for which he'd be right on target). Unfortunately, the reverse is not true. There have been numerous hijackings of Indian airliners into and through Pakistan over the last 30 years, and rightly or wrongly, Indian travellers have valid concerns.
All said and done, I have flown PIA from Bombay through Karachi and on to New York. A lot of Indians howled in protest when I told them I was doing that, but I figured it had to more interesting than, say flying on Lufthansa for an extra $ 300. I was a student then and the fare was dirt cheap. Karachi airport is a lot nicer than Bombay's airport, partly because security (in the early 90s) wasn't quite as tight as it was and is in Bombay. Also, it wasn't packed to the gills. Unfortunately, the PIA A300 arrives from BOM at about 3 in the afternoon and you sit around the KHI terminal surrounded by nothing but a few scowly guards with guns for 10 hours for the PIA 747 to JFK. Not much traffic on the apron either. There were about 20 other Indians making connections to Istanbul and Damascus as well, who were more intent on finding something to eat in the transit area. The PIA flight to JFK finally left on time, but made numerous stops (with delays at each) and we arrived at JFK 7 hours late, so all in all, it wasn't worth it.
Indians in general are a fussy bunch and the general consensus is that flying PIA isnt worth it because middle eastern carriers can offer good connections at lower costs than their European and American counterparts. Plus, as a friend put it, if I had to fly a subcontinental carrier, I'd stick with Air India, why PIA?
