LONG FLIGHTS ARE SUCH A BORE~luckily i have a survival plan for you:
-wear leggings, a tee, and a denim jacket (i know its hot out, but airplanes are chilly and denim jackets are v weather complaisant)
~wear dramatic lipstick! it'll distract people from under eye circles
~bring water!!! hydration is key on long flights so you don't go, like, brain dead
~bring a book or two and a journal to write in, those two things make time go by super fast
i hope you have fun in the Philippines!!
