“Round the World” service is a huge badge of honor, Pan Am used to offer a single flight that made stops and crossed both the Atlantic and Pacific Oceans.
After United bought Pan Am’s Pacific routes, it operated round-the-world service as well. It was a source of pride, not profits. At one point United flew New York JFK – Los Angeles – Hong Kong – Delhi – London Heathrow – New York JFK. United flights 1 and 2 traveled in opposite directions.
