Plus Ultra began Madrid-Buenos Aires flights on May 23, becoming the third Spanish carrier to link the two capitals and the fourth operator overall on one of the busiest air corridors between Europe and South America.
Who is flying the new Madrid-Buenos Aires flights?
An Airbus A330-200 operated the inaugural run, leaving Adolfo Suarez Madrid-Barajas on Saturday and touching down at Buenos Aires Ezeiza early Sunday after more than 11 hours. Plus Ultra has configured the aircraft for 299 passengers, with 24 business seats and 275 in economy, a layout the carrier describes as a balance of comfort and capacity.
Founded in 2011 by former Air Madrid executives, the airline already serves Bogota, Cartagena, Lima and Caracas, so Buenos Aires lifts its Latin American network to a wider footprint. Launch fares advertised near $640 round trip undercut the established carriers by close to half, a pitch aimed squarely at price-sensitive leisure and family travelers.
How fast will capacity grow on the route?
The route opens with two weekly rotations, departing Ezeiza on Thursdays and Sundays and returning from Spain on Wednesdays and Saturdays. From July the carrier doubles that to four, then adds a fifth weekly flight beginning July 12, timed to the European peak season when demand from Argentina runs highest.
The expansion arrives as the wider Spain-Argentina market adds capacity at a steep pace. By July, industry tallies put Plus Ultra at roughly 35 monthly frequencies against about 199 for Iberia, 88 for Aerolineas Argentinas and 62 for Air Europa, a sign of how concentrated and contested the corridor has become.
Why are Spanish airlines crowding into Argentina now?
The surge tracks a deliberate loosening of Argentina’s air market under President Javier Milei, whose deregulation drive cleared the way for foreign carriers to expand and to set fares without restriction. Argentine authorities formally authorized Plus Ultra through an official-bulletin disposition, the same open-skies framework that has drawn new entrants to the country’s international routes. Iberia is responding by flying the corridor entirely with its larger A350 fleet this summer and pushing Buenos Aires beyond three daily flights, a first for its long-haul network, while World2Fly, owned by Iberostar, is set to begin Madrid-Rosario service on October 1 with twin weekly A350 flights.
