i dont know why everybody else choses lan but i will give you my reasons.
every time i have flown them, the flight has left and arrived on time. The service has been amazing and the food was always good. the seats are nice (i love their buisness class), the cabin feels good and they fly my favorite plane (767) with a great looking livery.
i also fly them because they are one of the best members of one world and i just get sick of flying AA.
is the drinking age 16 on lan like in the rest of chile?
