What is the carry-on size limit for Iberia Express?

Iberia Express allows one carry-on bag up to 56×40×20 cm (22×15.7×7.9 in), including wheels and handles. The maximum weight is 10 kg.

Does Iberia Express charge for carry-on bags?

It depends on your fare. Basic (Optima) fares may restrict cabin bag access. Express+ and other higher fare tiers include a full-size carry-on in the cabin at no extra charge. Check your fare conditions carefully at booking.

Is Iberia Express the same as Iberia?

No. Iberia Express (IB Express) is a separate low-cost subsidiary of the Iberia group. It operates on short- and medium-haul European routes from Madrid. Baggage rules, fares, and fees differ from mainline Iberia.

Iberia Express Carry-On Rules (2026)

Iberia Express (IATA: I2) is the low-cost European arm of the Iberia group, operating flights primarily out of Madrid Barajas (MAD). While it shares branding with its parent, it runs separate fare structures and distinct baggage policies — meaning your Iberia carry-on rules do not automatically apply on an IB Express ticket.

Carry-On Allowance at a Glance

Item	Limit
Carry-on bag	56 × 40 × 20 cm (22 × 15.7 × 7.9 in), 10 kg
Personal item	Not explicitly defined — a small bag under the seat is generally tolerated
Liquids	EU 100 ml rule (100 ml containers, 1 L clear bag)

The 56×40×20 cm measurement includes wheels, handles, and any external pockets. If your bag exceeds this when stuffed, it may be gate-checked.

Fare Tier Breakdown

Iberia Express sells tickets under tiered fares. The carry-on included — and whether it goes overhead or not — varies:

Fare	Cabin bag (overhead)	Personal item (under seat)
Optima (basic)	Not included — must pay	Allowed (small bag)
Optima Plus	Included (1 × 10 kg)	Allowed
Express+	Included (1 × 10 kg)	Allowed
Flex	Included (1 × 10 kg)	Allowed

If you book an Optima base fare and want your bag in the cabin overhead, you must add a cabin bag to your booking before travel. Adding it at the gate or airport desk is more expensive than adding it online.

Tip: Iberia Express regularly offers cabin bag add-ons during the booking flow or via the "My Trips" section — always add it before heading to the airport if your fare doesn't include it.

What Counts Toward the Carry-On Limit

Iberia Express is fairly strict about the 10 kg weight and 56×40×20 cm size. Here is what counts:

Main cabin bag (roller or soft-sided)
Any attached pouches or travel pillows clipped to the outside
Items you are carrying in your hands when boarding (coat excluded)

A coat or jacket worn or carried over your arm is not counted. Duty-free purchases in a sealed airport bag are generally permitted in addition to your allowance on EU flights.

Bag Sizers and Gate Enforcement

Iberia Express uses bag sizer frames at some Madrid gates, particularly on busy leisure routes. Staff may ask passengers with oversized-looking bags to test them in the sizer. If your bag fails:

You will be directed to the desk to pay an excess bag fee (typically €50–€80 at the gate, higher than online prices).
The bag will be checked into the hold.
If the flight is very full, even correctly-sized bags may be gate-checked (hold) at no charge — this is not a penalty, just a space management measure.

Hub and Fleet Notes

Iberia Express is based at Madrid-Barajas Terminal 4 (T4). It operates a fleet of Airbus A319, A320, and A321 aircraft. Overhead bin capacity is adequate on most flights, though T4 departure gates can get crowded on peak travel days (Friday afternoon, Sunday evening).

Connecting through MAD on an IB Express intra-Europe leg to/from a mainline Iberia long-haul? Your baggage allowance for the entire itinerary may be covered under the Iberia long-haul ticket terms — check with Iberia directly if your bags are checked through.

Tips for a Smooth Experience

Book the cabin bag option early — it is cheapest at the time of initial booking.
Weigh your bag at home — a 10 kg limit fills up quickly with a laptop, shoes, and clothing.
Arrive at the gate early — overhead bins fill fast on A319 aircraft operating shorter routes.
Tag your bag — print the IB Express luggage tag from your booking confirmation and attach it. It speeds up any hold check at the gate.
Iberia miles? Iberia Express is part of Avios/Iberia Plus. Status does not generally grant extra carry-on weight, but top-tier members may receive priority boarding, which helps secure bin space.

Comparing Iberia Express vs. Mainline Iberia

Feature	Iberia Express	Iberia (mainline)
Carry-on size	56×40×20 cm, 10 kg	56×40×23 cm, 10 kg
Included in base fare	Fare-dependent	Yes (most fares)
Liquids rule	EU 100 ml	EU 100 ml
Hub	Madrid T4	Madrid T4

The mainline Iberia allowance is slightly deeper (23 cm vs. 20 cm). This is a meaningful difference for some hard-sided carry-ons — check your bag's depth before assuming it qualifies on IB Express.
