Airline hubs or hub airports are used by one or more airlines to concentrate passenger traffic and flight operations at a given airport.
 They serve as transfer (or stop-over) points to get passengers to their final destination.
 It is part of the hub-and-spoke system.
 An airline operates flights from several non-hub (spoke) cities to the hub airport, and passengers traveling between spoke cities need to connect through the hub.
 This paradigm creates economies of scale that allow an airline to serve (via an intermediate connection) city-pairs that could otherwise not be economically served on a non-stop basis.
 This system contrasts with the point-to-point model, in which there are no hubs and nonstop flights are instead offered between spoke cities.
 Hub airports also serve origin and destination (O&D) traffic.

The Sulimov dog (Russian: "Собакa Сулимова"), also known as the Shalaika (Russian: "Шалайка"), is a Russian jackal-dog hybrid originating from an initial hybrid between two Lapponian Herders and two Turkmen golden jackals.
 The breed was developed by Klim Sulimov for Aeroflot airline security.
 He is described as a Senior Research Assistant at the D.S. Likhachev Scientific Research Institute for Cultural Heritage and Environmental Protection.
 The primary use of this breed has been to aid airport security as sniffer dogs. Quoting Sulimov, "My dogs combine the qualities of Arctic reindeer herding dogs, which can work in temperatures as low as -70°C, and jackals which enjoy the heat up to +40°C.
 They're perfect for our country."
