If your itinerary only includes flights operated by Iberia, Iberia Express and Air Nostrum, you can select your seat and get your boarding pass from the moment you book. If your fare doesn't include seat selection, you can still book it in advance for less than you would pay at the airport and get your boarding pass. Alternatively, you can wait until 24 hours before the departure of your flight and then check in.
Remember, check-in for flights to/from Cuba, El Salvador, United States, United Kingdom, Guatemala, Mexico, Puerto Rico and China only opens 24 hours before the departure of the flight.

You cannot check in online and must therefore check in at the airport in the following cases:

• The departure airport does not permit online check-in.

• You are flying with a different operator. We'll redirect you to the relevant website if the operator is American Airlines, British Airways, Finnair, Latam or Vueling. In this case neither will you be able to add extra bags through Iberia.com.

• In the case of a special service: if you are travelling with a pet, you have booked a service for unaccompanied minors, or you were unable to prove your resident status, you can check in online but you will have to collect your boarding pass at the airport. In all other cases, you can only check in at the airport.

• You are travelling to/from USA, UK or China: the authorities in these countries may not allow you to check in online.

• For bookings with an Air Shuttle fare for more than one person.

If the message 'Your booking does not permit online check-in” appears when you are trying to check in and none of the above exceptions apply, try again in the 24 hours before the departure of the flight. If you still can't get your boarding pass you will have to check in at the airport.
