ITA Airways allows online check-in starting 48 hours before departure for most flights, except flights to and from the US and Canada, where online check-in opens 24 hours prior. Passengers enter their booking reference and last name to check in, select seats, add baggage, and choose how to receive their boarding pass, either via mobile app, email, or print at the airport. Some destinations require boarding passes to be collected at the airport. Airport check-in counters open 2 to 3 hours before international flights and 1 to 2 hours before domestic flights. Check-in closes 40 minutes before departure for domestic and Schengen flights, 60 minutes before for international flights, and passengers on US flights must arrive 3.5 hours early. Boarding gates close 15 minutes before departure. Special rules apply for minors, group bookings, special baggage, and reissued tickets.
