I Detect A Pattern
Singapore Changi Airport
Flights on Singapore Airlines leave from either Terminal 2 or Terminal 3 of Singapore Changi Airport.
Here's the way the departing flights are organized:
Africa: Egypt, South Africa
Europe: Russia, Turkey
Middle East: Saudi Arabia, U.A.E.
South Asia: Bangladesh, India, Maldives, Pakistan, Sri Lanka
Southeast Asia: Brunei, Indonesia, Malaysia, Philippines, Thailand, Vietnam
Americas: USA, Canada
Europe: Denmark, France, Germany, Greece, Italy, Netherlands, Spain, Switzerland, U.K.
North Asia: China, Hong Kong, Japan, Korea, Taiwan
Southwest Pacific: Australia, New Zealand
I'm sure it's a coincidence that flights to developed nations are from sparkly new Terminal 3 (pictured), while flights to the less developed nations that provide Singapore's manual labor are from older Terminal 2.
