This trip was not unusual in that it took 37 hours and four flights to get from Phnom Penh to Louisville, Kentucky, but because of the timing of the flights, it was difficult to get much sleep on the way.
The first stop was Singapore’s Changi Airport, always one of the top two or three airports of the world. It has indoor gardens, all sorts of environmental areas, an indoor waterfall, and even a bicycle trail for people on long layovers.
From Singapore, it was eastward to San Francisco and then on to Dulles in Washington, D.C. Dulles is notable for its shuttles (yellow circle) that go back and forth on the airport apron carrying passengers between terminals and concourses.
Dulles is also a major hub on the East Coast for United Airlines.
