It might come as a surprise to many to know the LEAP-powered A320neo is already doing tests outside Europe. The aircraft is now in Bolivia. This comes after flying into French Guiana on September 9.
It looks like Airbus has accelerated the LEAP testing, with no public statements.
After a request Airbus shared this with us: The A320neo is performing high altitude tests in Bolivia in La Paz and Cochabamba for a bit more than a week. The route the A320neo took was from Toulouse to Cap Verde, Cayenne and then Cochabamba. With regards to your questions on orders of tests, what happens is that we take opportunities in flight testing when they arise while ensuring our targets on certification and delivery.
