Thanks!
A long time ago...we arrived at Karachi Airport hoping to get tickets home that same day to Toronto. We didnt HAVE to have them, we just tried. For us it was ok if we didnt get them. We were told the plane was fully booked so daddy decided to turn around. When relatives heard about it, they called someone and got us seats. When we were going through the counter that same night we saw a man screaming his tickets got cancelled. In the bottom of our hearts, we knew we had cancelled someone elses tickets.
Sad isnt it. Thank god from that day on avoided PIA just inscase someone cancels our tickets:)
