I`ve been in the travel industry for almost 30 years, and the southwest code is WN. As a travel agency, we had to call them to make reservations, if we could use our computer system to book all the other airlines because they wouldn`t pay computer extras to be part of the system. Also, they didn`t have a ticket agreement with other airlines, so they wouldn`t allow us to expose part of the trip with another part of another airline on their tickets. After all, they wouldn`t transfer bags between themselves and other airlines. They would not serve meals. They were known as the would Not airline for travel agencies. They did not hand over any bags. You must have been in another company? Southwest has been an important source of inspiration for other low-cost carriers, and its business model has been repeated many times around the world. The competition strategy combines high personnel and aircraft productivity with low unit costs, reducing aircraft transit times, especially at the door.  European airlines EasyJet and Ryanair are two of the best-known airlines that follow Southwest`s business strategy on this continent. Other airlines with a business model based on Southwest`s system are Canada`s WestJet, malaysias AirAsia (asia`s first and largest LCC), India`s IndiGo, Australia`s Jetstar, a subsidiary of Qantas (although Jetstar now operates three types of aircraft), Philippines Cebu Pacific, Thailand Nok Air, Mexico`s Volaris, Indonesia`s Lion Air and Turkey`s Pegasus Airlines. While Southwest has been an important source of inspiration for many other airlines, including Ryanair, AirAsia, Lion Air and Jetstar, the management strategies of Ryanair, AirAsia, Lion Air and Jetstar are very different from those of Southwest.  All of these different management strategies can be seen as a means of differentiating other competitors in order to gain competitive advantages.
 Allegiant does not typically put passengers on other airlines after cancelling a flight, but provides, in rare cases, coupons that can be used by another airline if the cancelled flight has not been postponed, spokeswoman Hilarie Grey said. Relationships with international airlines represent significant revenues for other small U.S. airlines with no global reach. Alaska Airlines and JetBlue Airways have both aggressively negotiated deals with long-distance airlines and both rely on contracts with Emirates, allowing dubai passengers to travel to Boston, New York and Seattle to reach many U.S. destinations. In 2014, when JetBlue added a non-stop route from Boston to Detroit, part of the impetus was to ensure that Emirates customers could reach Detroit with a single stop.
