Hello,
My husband is flying out of FCO this weekend with his parents, and I'm trying to figure out when the counter opens. He has about five and a half hours between Airbnb checkout (nearish Termini) and the 3:20pm departure, so just enough time to not be able to do much before heading to the airport. However, he doesn't want to sit at the check-in counter for 1-2 hours if it isn't open, but if it will be, he doesn't mind just waiting a bit longer past security/passport control after checking bags.

Does anyone know the hours for the DL counter at FCO? Could not find it online. Thanks!
