I think it's safe to assume that the big GDSes hand over data to the US Government. Whether your flight goes anywhere near the US or the airline is US-based isn't really relevant - bookings cross national boundaries all the time:
Around 500 airlines and 95,000 travel agency locations depend on the Amadeus Data Centre to deliver almost half a billion net bookings every year and run extremely complex airline systems
Amadeus may have their main data centre in Erding, DE (just down the road from MUC) ... but do you really think they're exempt from "assisting" the US Government if push comes to shove?
Hint: David Miranda wasn't flying on a US airline, and his itinerary didn't involve an origin, destination or stopover in the US either.
