My votes are below. Not surprisingly, you'll see I love urban approaches, or ones that give you an awesome introduction to the place you're visiting:
- a treat basically no matter which runway you come in onn. 22 is the most dull, and it's not even that bad
- left side during approach to the 4s, great views of the city
- it's not particularly hair-raising, but still exciting to come in over such a massive city
- frighteningly close views of Chicago bungalows
- this one speaks for itself
- a controlled dive over the top of a hill, what's not to love?
- if you're coming from the south or southwest, you're over the city until just before touchdown - great views
- if landing from the east. Western approaches are super dull (Windsor Castle notwithstanding)
- something about the highland landscape around MAD
is just quintessentially Spanish; great sense of place
- citizens may hate the noise, but landing on the 16s, there is no doubt you're in Australia's capital!
- unbelievable views of the Southern Alps and a hair-raising corkscrew landing pattern
- massive city and water under the plane until the last moment
- you thought Los Angeles was big and bustling?
- gorgeous mountain scenery and great views of a beautiful little town
- slums, high-rises, beaches, roads choked with traffic. Welcome to India!
South & Central America
- same as the others, you're right over the city and it's a big one. Love that turn onto final right over Reforma.
- nothing like skyscrapers a few hundred feet below the wing
- the airport on a postage stamp. Spiral approach over the water, killer views of the city and a landing that needs a tailhook!
- steep descent over the mountains, the city appears out of nowhere, and you're over it until the last second
Africa & Middle East
- beautiful scenery and an interesting introduction to South African society - townships right under final approach
MQP - mountains all around and a bit of a "surprise" landing, since the airport is on a plateau
or VFA - with some luck and a seat on the correct side, you get a killer view of Victoria Falls
