Bailouts cause distortions in the market and make society poorer. When an airline goes bankrupt the planes don't disappear, the airline will be bought and made more efficient by the new owners. If there is demand for their service, people will keep their jobs, if there is no demand, all we will end up with is zombie companies supported by the taxpayer competing with more efficient companies. We are in this situation now because of the Central Banks reluctance to allow companies to fail after the 2008 financial crisis, and is exactly what the Austrian Economists warned about, to the few who bothered to listen.
What will be your attitude to bailouts when all British airlines have gone out of business and air travel in/to/from the UK is resumed by Air China Ltd.?
