It's four contrails, not three...look at the tip of the third one and you can see it actually has two tips. The second contrail also passes just in front of the tail, not on the other side. The angle makes it look like the "third" one is under the plane, but it's really on the other side; the Sun angle doesn't help as it's made the third and fourth contrails blend together. To me, that looks like an Airbus 580 from the shape of the nose, which is a four engine airplane.
