JFK to DXB with a stop in MXP (Emirates)
JFK to MNL with a stop in YVR (Philippines)
IAD to ADD with a stop in DUB (Ethiopian)
JFK to ICN with a stop in ANC (Korean Airlines)
Are they trying to get a chance to add more customers? Do they not have the right aircraft and find it easier to just make do with a refueling stop and the planes they have? I discovered that that Korean example is cargo, but it still baffles me. Also, these airlines are getting special permission to fly a leg of the trip that doesn't start or end in their home country, yes? I vaguely remember press about the Emirates example making European carriers mad for squeezing in on their turf.
Whenever I google this question I just get idiotic articles about "what is a layover" so I thought I'd ask. I did find on the Ethiopian wiki a note about a São Paulo to Guangzhou route they added via Lome and ADD, which with a grand total of over 18,000km makes more sense. Anyway I'm a bit nutty when it comes to routes, so thanks for your help in advance
