My goddaughters are joining us in BCN via Amsterdam as they return back to Canada from an Exchange program in Germany.

They just sent their flights to us - Iberia 5702 and 5703 - I checked the Iberia website and these flights are listed as "OP" - "operated by another airline" - my question is which airline? where do they check in? This is only their second flight ever and I can't lose them in Schiphol! Thanks for any assitance
