The Hanoi airport has to be the most confusing place I have ever been. For example, the departure information for your flights reads to check-in at "Area A" and "Area A" does not have a sign ANYWHERE designating it as "Area A", so what do you do?
Step 1: Go to one side of the Airport (through throngs and throngs of people flying both domestic and international who do NOT MOVE OUT OF THE WAY AND WILL ACTUALLY CLIMB OVER YOUR CART AND STEP ON YOUR BAGS TO GET IN FRONT OF YOU AHHHH!)
Step 2: See there is no counter for your flight.
Step 3: Curse and maybe accidentally scare kids
Step 4: Go to the other side of the airport (get more and more aggressive about getting through the crazy people who apparently like to hang out in airports and then decide to move only when sweaty, irritated girl decides she wants to get through).
Step 5: See there are no signs for your flight
Step 6: Go outside to calm down and maybe fling yourself into oncoming traffic
Step 7: Repeat
The entryway for the departure gates is HIDDEN. I. kid. you. not. UNDER THE STAIRS. Where more non-flying people like to hang out.
This picture should do my last hour of hell a bit of justice:

My friends, you cannot see the arrow on the left clearly, but these are two signs, saying the same f'ing thing, POINTING AT EACH OTHER. I finally pinned a poor woman to the ground and demanded she show me where in the hell to go...and maybe sweated on her...a bit...on accident...sorry, nice lady. Mama needs a drink.
