Plus Ultra Líneas Aéreas S.A. is a Spanish long-haul airline based at Adolfo Suárez Madrid–Barajas Airport.

Plus Ultra was founded in 2011 by the former director of now-defunct Air Madrid, Julio Miguel Martínez Sola.

It is taken from the personal motto of Charles V, Holy Roman Emperor and King of Spain, and is a reversal of the original phrase Non plus ultra ("Nothing further beyond").

[citation needed] On 15 June 2016 the airline started operating regular flights, with destinations such as Santo Domingo and Lima.
