I always asked for a window seat, so I can use the towel/blanket
as my pillow to prop at the window for snoozing. Plus....I dont
need to go toliet often.
The airplane usually supplies blanket. I always use it to cover
until my feet, then secure the seatbelt over it, then my own
blanket to either prop my lower back or use to prop my head.
Water bottle is used to take water from the airport to drink when I
see one, so I wont be wasting money buying bottle drinks at
stopovers. Always empty out your bottle before you board the plane
though. Great for touring since most tourist attractions has water
cooler dispensers everywhere.
Buying the drinks at those tourist spots is very very draining of
your pocket.
