What does the blue sky mean?

Blue Air is a low-cost airline located in Bucharest, Romania. From June 5, 2004 to February 2004, it provided regular flights to all parts of Europe. Its base airport is Berniasa-aurel vlaicu International Airport in Bucharest (a small airport in Bucharest, also known as Bucharest B? Neasa), its routes are concentrated in Allard, Cluj-Napoca, Baku and Sibiu in Romania, covering the whole of Romania. Thanks to 1992 Europe's deregulation of the aviation industry and the company's own low-cost strategy, Blue Airlines has achieved rapid expansion and has now developed into one of the airlines with the largest number of passengers in Central Europe. The airline from Bucharest to timisoara was opened at the beginning of its establishment, but it was forced to give up in March 2005 due to the competitive pressure of Romanian airlines and railways. Since then, on June 29th, 2006, Lanhang has opened the route from Bucharest to Cluj-Napoca International Airport (this route uses Boeing 737). From June 5438+065438+ 10, 2006 until other low-cost airlines such as Wizz Air, Germanwings, MyAir and EasyJet entered the Romanian market, Blue Airlines has always been the cheapest airline in Romania, and it often offers discounts on major routes so that the public can buy air tickets in major European cities cheaply.
