SAO PAULO, July 17 (Reuters) - Swiss airline Helvetic Airways signed a letter of intent to buy twelve E190-E2 passenger jets made by Brazil's Embraer SA, according to a securities filing during the Farnborough Airshow on Tuesday.
Helvetic would also acquire options to buy another dozen of the same aircraft or convert to the longer E195-E2 aircraft. The new planes, worth $1.5 billion at list prices if Helvetic takes all 24, will begin substituting the carrier's Fokker 100 and current-generation E190 aircraft between late 2019 and early 2021.
Mauritania Airlines also signed a firm order for two E175 jets to be delivered next year, according to a separate filing. (Reporting by Alberto Alerigi Jr. and Brad Haynes Editing by Chizu Nomiyama)
