If you’re planning to travel to Spain this year or next, there’s some news that could completely change your travel budget. Plus Ultra Líneas Aéreas, a Spanish airline that until recently operated in Lima, Bogotá, Cartagena, and Caracas, will begin flying between Ezeiza and Madrid-Barajas starting in May. The news: fares for travel from Buenos Aires to Madrid are cheaper than the competition and also include in-flight meals and checked baggage.
What is Plus Ultra, the new airline flying between Buenos Aires and Madrid starting in May with tickets starting at US$930, including checked baggage and in-flight meals
Plus Ultra is not a new airline: it has been operating routes in Latin America for over a decade, has a presence in 18 countries, and combines competitive fares with included services that other low-cost carriers do not offer.
This new airline will begin flying between Madrid and Buenos Aires on May 23, 2026, with two initial weekly flights that will increase to four weekly flights starting in July. A third flight will be added starting in June.

If you know anything about airplanes, you might be interested to know that Plus Ultra will be using an Airbus A330-200 with evening departures from Madrid at 11:00 PM and daytime departures from Buenos Aires at 12:35 PM. You’ll leave Ezeiza at noon and arrive in Spain the next morning, without losing a full day of travel.
Prices matter: How much does it cost to fly from Buenos Aires to Madrid, all-inclusive?
Promotional fares for flights from Madrid to Buenos Aires start at US$930 round-trip in economy class with baggage included, and US$2,780 in business class—much less than a regular ticket to Madrid, which costs around US$1,300 or more, so paying less than that with a suitcase included is considerably cheaper.
There are more basic fares with baggage restrictions, so it’s a good idea to carefully review what each option includes before booking. Plus Ultra guarantees at least one free checked bag on all its international fares.
How to Book
Tickets are now on sale on the official Plus Ultra website (plusultra.com) and through online travel agencies. If you find introductory fares, don’t miss out: these types of promotional prices tend to sell out quickly, especially for weekend dates or during peak season.
