If your bag is too big at the gate

Over the size or weight limit? Check it in at the desk before security (your fare's bag fee applies) to avoid gate surcharges and delays.

It’s almost always cheaper to add the right bag when you book or online before you fly.

Other Iberia cabin rules worth knowing

You can swap roles, e.g. a large backpack up to 10 kg in the locker and a very small case under the seat, if each meets its own limits.
On Iberia Regional Air Nostrum flights, your 10 kg bag is taken at the aircraft door, carried in the hold free and returned at the aircraft.
On very full flights Iberia warns you by email or WhatsApp and checks your 10 kg bag free at the desk or gate, whatever your ticket.
Power banks: max 2 per passenger (max 100 Wh each); they can't go in the overhead lockers or be used on board.
A guitar or other instrument up to 30 × 120 × 42 cm can be your only piece of hand luggage. With an infant, bring 1 extra bag for baby items.
If another airline operates your flight, its hand luggage rules apply.

Power banks on Iberia

Iberia allows up to 2 power banks of up to 100 Wh each, in the cabin only, and you can't use them at any time during the flight.
