What is the primary reason airlines enter into aircraft purchase agreements?

Airlines primarily enter into aircraft purchase agreements to expand their fleet capacity. By acquiring new aircraft, airlines can increase their available seating and cargo space, allowing them to serve more routes, accommodate higher passenger volumes, and ultimately enhance their competitiveness in the market. Expansion of fleet capacity is crucial for airlines to meet rising travel demands, explore new markets, and maintain or grow their market share.

While enhancing passenger comfort and improving fuel efficiency are important considerations in the design and selection of aircraft, they are often secondary advantages that come with the choice of specific models rather than the primary motivation for acquiring new aircraft. Additionally, securing cargo space is relevant but more specific to certain airlines or markets, and fleet expansion encompasses a broader strategic objective that aligns with overall business growth.
