In an effort to save costs during financially challenging times, such as during the COVID-19 pandemic, many low-cost airlines curtail their investments in new planes. Due to decreased travel demands, these airlines find it more financially viable to retain and maintain their existing fleet rather than investing in new ones. This allows the airline to save money, which is integral to their overall survival strategy during financial crises.
However, the specifics of where and on what particular aspects airlines are cutting back may vary greatly depending on various factors such as their financial health, region, government support, and more. It’s best to check with the specific airline or consult recent news for more accurate and detailed information.
