No offense intended, but what are they expected to say? Aerocontinente and Lan Peru have been going at blows from the day that LP began operating. Whether there's truth to it I suppose will never be known since AC accused LP of causing them to be grounded a few years ago as well yet nothing came of it. But if even if they did then fine. The US isnt going to ban an entire airline without more than allegations from one of its competitors.
