Southwest has been a major inspiration to other low-cost carriers, and its business model has been repeated many times around the world. The competitive strategy combines high level of employee and aircraft productivity with low unit costs by reducing aircraft turn around time particularly at the gate.  Europe's EasyJet and Ryanair are two of the best known airlines to follow Southwest's business strategy in that continent. Other airlines with a business model based on Southwest's system include Canada's WestJet, Malaysia's AirAsia (the first and biggest LCC in Asia), India's IndiGo, Australia's Jetstar, a subsidiary of Qantas (although Jetstar now operates three aircraft types), Philippines's Cebu Pacific, Thailand's Nok Air, Mexico's Volaris, Indonesia's Lion Air and Turkey's Pegasus Airlines. Although Southwest has been a major inspiration to many other airlines, including Ryanair, AirAsia, Lion Air and Jetstar, the management strategies, for example, of Ryanair, AirAsia, Lion Air and Jetstar differ significantly from those of Southwest.  All these different management strategies can be seen as means of differentiation from other competitors in order to gain competitive advantages.
