Airlines can buy slots at airports through a variety of means. Some slots are allocated by airport authorities through a process that may involve auctions, lotteries, or historical precedence. Airlines can also acquire slots through negotiations with other airlines, buying or leasing them directly. Additionally, airlines may obtain slots through mergers or acquisitions, where they inherit the slots of the acquired airline. Overall, the process of buying slots can be competitive and complex, as they are a valuable and limited resource at congested airports. **

Furthermore, some airlines may have established brand identities and customer bases that are not aligned with the budget airline model. **
