I admit it, U.S. domestic carriers make me crazy some days, with their various fares and rules that seem arbitrary at best and flat out stupid at worst. It seems, the best foreign carriers leave many of their domestic competition in the dust. Then there are the moments that put it all in perspective, such as my family’s experience with Vietnam Airlines for a roundtrip from Saigon-Ho Chi Minh to Siem Reap earlier this week.
