Hello, first post here so apologies if this is the wrong place --
I have an amex platinum and they are currently running a few airline offers. Ex: Spend 500 on Aerolineas Argentinas and get 100 back; spend 1000 on ANA and get 20,000 points. I don't have enough time off to travel internationally, but I *DO* need to travel domestically quite a bit. Those two airlines are both part of alliances with US carriers. Is there a way to book domestic US flights through those airlines?
No. Only if you are connecting from an international flight on the same ticket. Aerolineas Argentinas and ANA cannot sell you a domestic only US ticket.
You can see the limited situations in which codeshares are approved here:
https://www.transportation.gov/sites...e%20Report.pdf Purely domestic legs are "Type 1": "Foreign carrier operates its own service between homeland and a point in the United States; U.S. carrier
transports foreign carrier passengers within United States-- code share is on U.S. domestic leg."
