Hi good to hear that you are comming this Friday. Darne ki koi baat nahi as Mahmed sister said you will make friend during your flight and who know a girl sitting next to you also comming 1st time after receiving visa.
I recommend you bring your own 3 Aurtein 3 kahania latest edition magzine to read. Once you finish novel you can play colour matching and brick breaking game available in PIA
than eat your lunch and have a sleep for 2-3 hrs than wake up and have your lali powder ready on you as you are very close to land. Thats it
