My suggestion would be to just use the US passport for everything except when physically encountering EU/Schengen passport control — in other words, stick to loading in the US passport info into the reservations.
Recently ran into a US airline rep who tried to scan a US citizen’s European card/ID into a reservation because the rep thought it was required because the person was flying on a one-way ticket to the Schengen area. I eventually had to inform the agents that they shouldn’t be scanning in US citizens’ non-US ID into the reservations for US-EU trips, as CBP would prefer the reservations be loaded with the US passports’ info and not override by some European cards’ MRZ info. Should have know there would be an issue when i heard them say that the passengers should show up 2-3 hours in advance for check-in on international flights when the airport doesn’t even have international flights.
