Latin American low-cost operator Viva Air has selected the Airbus A320 to expand its fleet.
It is intending to acquire 50 aircraft, including 35 re-engined A320neos and 15 baseline A320s, for its operations.
Airbus says the agreement is the subject of a memorandum of understanding.
Viva Air is owned by Irelandia Aviation and has divisions in Peru and Colombia.
VivaColombia chief William Shaw confirmed the acquisition plan for the carrier during the Paris air show.
He says the A320neos will be delivered from 2020.
The aircraft will be used to underpin international expansion of VivaColombia and Viva Air Peru.
VivaColombia has 26 routes, says Shaw, of which four are international. The Peruvian operation has yet to establish an international presence.
"The jury is still out on whether to go a little north of Colombia or a little south of Peru," says Shaw.
No engine selection has been disclosed. Shaw says the company is "currently taking bids" and will make a decision "soon".
VivaColombia currently has nine A320s and Viva Air Peru has two, all fitted with a 180-seat all-economy layout.
