MEXICO CITY, Dec 19 - The proposed merger of Mexican budget carriers Volaris (VOLARA.MX), opens new tab and Viva Aerobus aims to put the new airline group in stronger conditions to negotiate its highest costs, acquiring and renting aircraft, executives from both firms said on Friday.

Reuters exclusively reported on Thursday that the two were nearing an agreement, which Volaris and Viva later confirmed

Notably, major global carriers operate with ownership costs up to 60% lower than their Latin American counterparts, including Viva and Volaris," he added.

Both airlines exclusively fly Airbus (AIR.PA), opens new tab planes, and operate similar routes.

While Volaris and Viva will continue to operate as separate brands, the new group - to trade as Grupo Mas Vuelos - would become Mexico's largest domestic carrier by far..

Shares of Volaris were on track for their best day ever, shooting up nearly 17% after the call.

Under the terms of the agreement, the companies will combine in a merger of equals. Volaris CEO Enrique Beltranena conceded that his carrier represented about 60% of enterprise value while Viva brought in 40%, though Volaris' net debt was higher.

Among Mexican carriers, the two represented a combined 69% of passengers carried in the year through October. They were trailed by flagship airline Aeromexico , which is likely to oppose the merger.

"We're confident in the merits of this transaction," Beltranena said. "(We) prefer right now not to speculate on the results or the potential outcomes, and conditions or remedies" stipulated by the regulator
