<h3>Hello there!</h3>
Your question asks how airlines compete with each other if they don't change their prices.
<h3>Answer: By giving the customers better service.</h3>
If an airline company doesn't want to change their prices for a flight, but still want to compete with other airlines, then they would try to compete by providing more and better services to the customers.
When an airline competes with providing better services, it attracts customers to choose them because customers could feel more comfortable on their flight.
Airlines can compete by providing:
- Wi-Fi
- More space
- Entertainment
- Food
Airlines now a days are starting to provide Wi-Fi services to its customers in the aircraft. Since we live in a world that needs Wi-Fi for electronical things, airlines are providing Wi-Fi in order to have people choose their airline for their flight. Providing Wi-Fi to its customers will not only bring in more customers, but can keep people busy on the flight, having no disruptions since people would be focused on their personal stuff on their laptop/phone/etc.
Airlines are also competing by providing more space in their cabin. People that go on flights feel very cramped in their seat; having little leg room between their legs and the seat in front of them. Airlines are making more leg room and space for the customers in order for them to enjoy the flight. This is luring in customers because customers want to feel comfortable, and space is the main thing that customers want in their flights.
Airlines are also competing by providing entertainment. The entertainment part of an aircraft is in the little screen that would be in front of the customer, behind the seat in front of them. This entertainment service would entertain people on their flights. This entertainment service could provide movies, world map, and etc. Flights are boring, and so airlines are trying to make the flights more entertaining.
Airlines are also competing by providing better food. Who doesn't get hungry on the plane? If airlines are giving terrible food, why would someone want to choose that airline again? Airlines are providing better food in order for customers to choose them as their airline. Food is a major thing that lures people into different airlines. This is something that airlines are trying to improve all the time.
To sum it all up, these are just some of the ways airlines compete with each other, without having to change the price of their flights.
