What constitutes a bad airport is debatable depending on the region you fly into. Here are my top 5 bad regions/airports and the reason why, in no particular order, just bad full stop:
1. Any Mexican Airport. There is a dispute with the baggage union that is never ending. You can collect your luggage from the carousel and put in on a trolley to clear customs, however, as soon as you leave the secure area, you need to unload your luggage from your trolley, leave your trolley behind the barricades and either pay a porter to transport your luggage for you or schlep it yourself. Screwed up situation #1.
2. USA. I get that we need to collect our luggage and that everyone coming in is a potential terrorist, just don't make me feel like a terrorist for coming to your country, and at the same time as you treat me as a terrorist, no I am NOT giving you a tip. Treat me like a human being and I might sling you a couple of bucks. Screwed up situation #2
3. Canadian Border Protection. I have a Permanent Resident Visa. I can come and go as I please. The reason for my "visit" to Canada is None Of Your Business. Bugger Off. Screwed up situation #3
4. A Visa for Brazil and Brazilian Federal Police at the airport. You just hosted the World Cup and are about to host the Olympic Games. Do you really want to process that many Visa's? Getting through your Immigration on a legitimate work visa is bad enough, do you really need to make it worse? Come on Brazil, get it together. Screwed up situation #4
5. LHR. Come on guys. Really? Screwed up situation #5
