Indigo’s low-cost business model

IndiGo operates as a low-cost carrier (LCC) airline and its business model is to seize opportunities to minimize operating costs to maximize profits.

A low-cost airline keeps its base fare lower than other airlines by cutting back on the services it offers in exchange for giving passengers a lower price compared to a full-service airline, according to OAG Aviation data.

A simple example of this is that IndiGo does not serve hot meals, which eliminates the need for food warmers on board and hence saves costs in weight and fuel usage.

So, while a full-service carrier like Air India will give you a hot meal included in your flight ticket prices, carriers like IndiGo operate on a low-cost basis. However, Air India operates a separate low-cost arm called Air India Express.

IndiGo also makes huge savings from using only Airbus aircraft; This eliminates the costs of training pilots for a separate Boeing installation. The company also operates on a lease-based model where IndiGo operates an aircraft under lease; This gives the airline high flexibility without the risk of owning many expensive assets that lose value over time.
