You think Newark sucks? Try Léopold Sédar Senghor International Airport:
Location: Dakar, Senegal
Firsthand account: “There is only squalor, an unnerving sense of confinement, and to some extent danger.” Patrick Smith, Salon.com, May 25, 2007
Why it’s so bad: Because it’s standing room only. As a regional hub, an ordeal at Senghor is often unavoidable for travelers to West Africa. Once you’re in the terminal, don’t plan on relaxing: There are no seats, and guards will advise you to stop loitering if you hang around in one spot too long. Immigration lines can take up to three hours. And in any event, it’s best to keep moving since you can expect to be surrounded by vendors selling counterfeit goods and unofficial “porters” who will pressure you into hiring their services if you happen to come to a standstill.
Foreign Policy tells you where else to avoid here.
