Brian Air is a company that is trying to break into the air transport market.

Explanation

Barriers to entry are economies of scale (in the air travel industry you can't just start off small and grow), access to capital (you need to already have a lot of money to buy airplanes) and licences and permits (you need to ensure you have the correct licences to fly planes). These are listed on p.41. Other barriers include; strong brand identity already dominant in the market, high switching costs for buyers, access to distribution networks and government policy.
