Iberia and American Airlines are Oneworld alliance partners, not direct competitors in the traditional sense. Both airlines codeshare and recognize each other’s frequent flyer programs. The comparison only becomes relevant when both operate the same route, primarily transatlantic flights between the US and Spain/Europe, or when choosing between connecting options via Madrid vs a US hub. On those routes, here’s how they stack up.
Route Networks
Iberia is Spain’s flag carrier, based at Madrid Barajas (MAD). Its strongest routes are Spain and Europe to Latin America. Iberia has deep coverage of South American capitals from Madrid that no US carrier can match. For the US, Iberia flies nonstop to New York (JFK), Boston, Miami, Chicago, and Los Angeles, with many more cities served via Madrid connections.
American Airlines has one of the largest networks in the world (350+ destinations, 50+ countries) and far more US domestic coverage than Iberia. American serves Madrid directly from several US hubs and competes with Iberia on transatlantic routes. For purely domestic US travel, Iberia doesn’t fly and American is the only option between the two.
For traveling to Latin America specifically, Iberia’s Madrid hub is a genuinely useful connecting option, especially for Spanish-speaking destinations in South America where Iberia has more frequencies and direct service than most US carriers.
In-Flight Service and Premium Cabins
Iberia’s Business class (Business Plus and Business) has received consistently positive reviews, particularly on long-haul flights. Their A350 and A321XLR-operated routes have modern flat-bed products in a competitive configuration. Economy meal service on transatlantic Iberia flights is generally well-regarded compared to American’s long-haul economy meals.
American’s Flagship Business product (on 777s and A321Ts) is competitive, though the older 777 interior is starting to show its age on some aircraft. American’s Main Cabin Extra (extra legroom economy) is a useful middle tier that Iberia doesn’t precisely replicate.
On comparable routes, Iberia generally earns slightly higher customer satisfaction scores on international routes. American’s advantage is breadth of network and more US departure points.
Loyalty Programs
Both airlines use Avios as their loyalty currency. Iberia Plus and British Airways Executive Club both earn and redeem Avios, and these programs are interconnected. Iberia Plus Avios can be transferred to British Airways Executive Club and vice versa. American AAdvantage is a separate currency but redeemable on Iberia flights as an Oneworld partner.
- Iberia Plus: Earns Avios. Avios are particularly valuable for short-haul redemptions within Europe/Spain. Iberia-specific redemptions to Spain and Latin America are often good value. The shared Avios pool with British Airways adds versatility.
- American AAdvantage: Miles usable on Iberia flights as an Oneworld partner. Better for US domestic redemptions and upgrades on American metal.
Baggage Fees
- Iberia: Checked bags vary by route and fare class. Transatlantic Iberia fares often include one checked bag in the base fare, especially on Economy class (varies by fare bucket). Within Europe, bags are typically purchased separately.
- American: First bag $35, second $45 on most domestic routes. On international routes from the US, the first checked bag is typically included.
Verdict
Choose Iberia if: You’re flying between the US and Spain, traveling to Latin America from Europe, or you want to build up Avios through Iberia Plus for future Spain or Europe travel. Iberia’s Madrid hub is genuinely excellent for European and Latin American connections.
Choose American if: You want more US departure cities for transatlantic flights, you prefer AAdvantage miles, you need US domestic connectivity on the same ticket, or American’s timing or price on your specific route is better.
Iberia vs American Airlines: Frequently Asked Questions
Are Iberia and American Airlines partners?
Yes. Both are members of the Oneworld alliance. They codeshare on many transatlantic routes and have an interline relationship. AAdvantage miles can be used to book Iberia flights, and Iberia Plus Avios can be used to book American flights.
Is Iberia good for flying to Latin America?
Yes, particularly for South America. Iberia’s Madrid hub offers nonstop connections to more South American capitals than most US airlines. If you’re traveling from the US to South America, a connection through Madrid on Iberia can be a competitive alternative to routing through a US hub.

Yes. Iberia Plus and British Airways Executive Club both use Avios and are interconnected. You can transfer Avios between the two programs, which adds flexibility for redemptions across both airlines’ networks.
Which has better business class: Iberia or American?
Comparable, route-dependent. Iberia Business on A350 routes is well-reviewed. American Flagship Business on 777 routes is established but the interior is older on some aircraft. Check the specific aircraft operating your route on both carriers before choosing based on premium cabin quality.
Can I earn AAdvantage miles on Iberia flights?
Yes. As Oneworld partners, AAdvantage members can earn miles on Iberia-operated flights. The earning rate depends on your AAdvantage elite status and the fare class booked.
Does Iberia fly domestic US routes?
No. Iberia does not fly within the United States. It only operates international routes connecting Spain and Europe to international destinations. For US domestic travel, American Airlines is the relevant carrier between these two.
