The reason Pakistan international airline is flying to Athens is because there are so many number of Pakistani people living there.
There are some 200,000 Muslims living in Athens. Now that is alot of Pakistani people
Back in 2006 PIA did make some profit as well when they were flying to Athens
I'll accept that there are Muslims living in Athens. I'll accept that there are Pakistanis living in Athens. I do not accept that all 200,000 Muslims living in Athens are Pakistani nor that all Pakistanis living in Athens are Muslims.
