The Economics in perspective

From Bratislava, the capital of Slovakia to Košice, near by Prešov (Viper and Skyper production headquarters) it is 1 hour 23 min as the crow flies for € 28.4, while it takes 4 hours 16 min and costs € 51 in a luxury car of the same price as the plane, if the traffic is clear, that is. It isn’t any better by train either.In the sky, there are no traffic lights, traffic jams, detours or roadworks. If you want to have a rest, switch on autopilot and let it fly you all the way to the start of the runway.
