Kuznetov is very reliable carrier for its age. Russia does not spend on its maintenance and training needed for long sustain voyages.
In Syria it went with complex airwing of Su-33, MIG-29K and Ka-52K (Strike sorties aka bomb laden they counted 420 with 127 night with 4 targets per sortie) against Syria and quick pilot recovery after crash landings. and another large scale training Exercises next to Libya to demonstrate to Libya Haftar and he was brought on board.. If Carrier was really effective tool in Mideast than priority on Carrier building and operations will be much higher. and it is not just this Carrier. Russia also sent that Tu-214R twice and as they wanted to intercept some thing to enhance confidence in the region on them. pay attention to word confidence. Those residing in Mideast have intelligence observation.
Su-33 were equiped with wing tip pods.

I think describing the service life of Kuznetsov as anything more than a tragicomedy is already being quite generous, but calling it reliable for its age and describing its Syrian deployment as anything resembling a success is wild.
