A codeshare is a ticketing agreement where multiple airlines sell seats on the same physical flight under their own flight numbers. The operating carrier provides the aircraft and crew, while the marketing carriers simply list the flight in their booking systems. This allows airlines to offer passengers a wider network of destinations without having to deploy their own hardware on every route.
It's a Delta aircraft, but we're booked on the Air France codeshare so check in at their desk.
