Air Nostrum (Iberia Regional) allows one carry-on bag up to 10 kg (56 x 40 x 25 cm) and one personal item per passenger. Free checked baggage depends on your Iberia fare type Economy Basic includes zero free bags. Overweight fees range from €12–€15/kg on European routes up to $110 on transatlantic flights. Special baggage on Air Nostrum can only be added at the airport.

Air Nostrum operates Spain’s regional air network under the Iberia Regional franchise, flying smaller aircraft the CRJ1000 and ATR72-600 to dozens of domestic and short-haul destinations. Because its fleet is more compact than a mainline Iberia aircraft, the baggage rules carry a few important quirks that most travelers overlook. Show up uninformed and you could pay significantly more at the airport than you would have online.

What Is Air Nostrum’s Baggage Allowance?

Air Nostrum’s baggage allowance includes one carry-on bag, one personal item, and a number of free checked bags that depends entirely on the Iberia fare type purchased. Economy Basic passengers receive zero free checked bags. Higher economy fares and Business Class include one or two bags. All checked bags must weigh no more than 23 kg and stay within 158 cm in total linear dimensions.

Because Air Nostrum flies as Iberia Regional, tickets are booked through Iberia and governed by Iberia’s fare structure. Your baggage allowance is printed on your ticket if it reads “Baggage Allowance: 0PC,” no free hold baggage is included.

Air Nostrum Baggage Allowance by Fare Class

What Is Air Nostrum’s Carry-On Baggage Allowance?

Air Nostrum allows one carry-on bag weighing up to 10 kg with maximum dimensions of 56 x 40 x 25 cm, plus one personal item (such as a handbag or laptop bag). However, because Air Nostrum operates smaller regional aircraft, your carry-on bag may be collected at the aircraft door and stored in the hold free of charge if overhead bin space is limited.

Air Nostrum Hand Luggage Allowance at a Glance

Edge case to know: Upgraded Points notes that some sources reference an 8 kg / 45 x 35 x 20 cm carry-on limit specifically for Air Nostrum, which reflects the aircraft-door collection scenario. The Air Nostrum official website lists 10 kg and 56 x 40 x 25 cm as the standard. If you are connecting from a mainline Iberia flight departing the US, you are restricted to one carry-on piece regardless of cabin class a US federal security requirement, not an Air Nostrum rule.

What Is Air Nostrum’s Checked Baggage Allowance?

Air Nostrum’s checked baggage allowance permits bags weighing up to 23 kg with total linear dimensions (height + width + length) not exceeding 158 cm. Bags between 24 kg and 32 kg incur an overweight fee. Bags above 32 kg are not accepted under any circumstances.

Key rules:

• Handles, wheels, and pocket compartments are included in the dimension measurement
• Keep your baggage receipt from check-in through to your final destination
• Label bags inside and out with your name and contact details

Air Nostrum Economy Baggage Allowance

Economy passengers on Air Nostrum are subject to Iberia’s fare-based system. Economy Basic the cheapest Iberia fare includes zero free checked bags. This catches a large number of travelers off guard. Economy Optional, Comfort, and Flex fares include one free checked bag of 23 kg.

Real-world cost scenario: A traveler booking Economy Basic on a Madrid–Valencia route and wanting to check one bag will need to purchase baggage separately. Online prices are always lower than airport prices, so purchasing at check-in online rather than at the desk is consistently the cheaper option.

Air Nostrum Business Class Baggage Allowance

Business Class passengers on Air Nostrum receive the most generous allowance. Business Comfort, Flex, and Promotional fares include two free checked bags of 23 kg each on short and medium-haul routes. Business Optional includes one free checked bag on these routes.

Business Class passengers also receive free overweight allowance meaning bags between 23 kg and 32 kg are transported at no extra cost, regardless of the route. This is a significant perk for heavy packers.

What Are Air Nostrum’s Baggage Fees?

Air Nostrum baggage fees align with Iberia’s pricing structure, since tickets are booked through Iberia. Online prices are consistently cheaper than airport prices. Additional checked bag fees vary by route, fare class, and whether you purchase before or after arriving at the airport.

Overweight Baggage Fees by Route

Calculated example: A 28 kg bag on a flight from Madrid to New York (if connecting via Iberia) would trigger a $110 overweight surcharge in Economy, on top of any checked bag fee already paid. The same bag in Business Class travels free of overweight charges.

What Are Air Nostrum’s Excess Baggage Fees?

Air Nostrum’s excess baggage fees apply when passengers carry more bags than their fare includes or when bags exceed the 23 kg weight limit.

For odd-shaped or irregular bags, a 2026 surcharge now applies across the Iberia Group, including Air Nostrum-connected flights. Soft-sided, rounded, plastic-wrapped, or non-rigid bags items that may interfere with automated baggage handling are assessed separately:

• Spain (domestic, excluding Canary Islands): €35 direct / €40 connecting
• Canary Islands, Europe, North Africa, Middle East: €60 direct / €70 connecting
• Americas and Asia: €125 direct / €140 connecting

These charges stack on top of standard checked bag fees. If you regularly pack in a soft duffel or rounded bag, switching to a rigid rectangular suitcase avoids this surcharge entirely.

Can Iberia Plus Members Get Extra Baggage on Air Nostrum Flights?

Yes. Iberia Plus loyalty members traveling on Iberia Group flights which includes Air Nostrum receive additional baggage benefits based on their tier level:

• Platino and Infinita members in Business Class can take a second additional bag free of charge

• Overweight allowances are waived for top-tier members on qualifying routes

These waivers apply specifically to Iberia Group flights. They do not apply to IB26XX flight numbers.

What Are Air Nostrum’s Rules for Special and Sports Baggage?

Sports equipment fees (airport-only for Air Nostrum, indicative Iberia Group rates):

• Golf, ski, scuba, fishing: from €60–€66 at the airport for Spanish domestic routes; from €130–€170 for long-haul
• Bicycles: from €65–€72 at the airport for Spanish domestic routes; from €150–€165 for long-haul

How Does Air Nostrum’s Policy Compare to Competitors?

Air Nostrum is more generous than Ryanair in terms of carry-on dimensions and does not charge for the Delivery at Aircraft service. Vueling charges a flat €45 per flight for sports equipment potentially cheaper than Air Nostrum’s airport-only rates on short-haul. For travelers connecting from a long-haul Iberia flight, the checked bag allowance from the long-haul leg typically carries through to the Air Nostrum regional segment.

Pack Smart: How to Avoid Extra Fees on Air Nostrum

• Buy baggage online before you fly. Airport prices are always higher than online rates, and some baggage types cannot be purchased at the desk
• Use a hard-sided, rectangular suitcase. Soft or rounded bags trigger the 2026 irregular baggage surcharge
• Weigh your bag at home. Overweight fees start at €12/kg on European routes a postal scale costs less than one overweight charge
• Check your fare type before assuming you have a free bag. Economy Basic never includes hold baggage, even on short domestic routes
• Arrive early if checking special equipment. Air Nostrum requires airport-only processing, so extra time is essential
• If you’re an Iberia Plus member, confirm your tier benefits apply to your specific Air Nostrum flight number before relying on additional allowances

Can I book special baggage (sports equipment) online for Air Nostrum?

What is the maximum weight Air Nostrum accepts for a single checked bag?
The maximum accepted weight is 32 kg. Bags between 23 kg and 32 kg incur an overweight fee. Any bag exceeding 32 kg will not be transported under any circumstances.

What is the Delivery at Aircraft service and is it free?

Potentially. An instrument no larger than 30 x 120 x 42 cm approximately the size of a standard guitar may travel as cabin baggage alongside a personal item.

How much does an overweight bag cost on a domestic Spanish Air Nostrum route?
Overweight fees on European and domestic routes are charged at €12–€15 per kilogram above the 23 kg limit. A bag weighing 27 kg would cost between €48 and €60 in overweight charges alone more than the cost of checking a second bag on many European fares.
