What makes Easyjet different to many other Low Fare Airlines?
Analysing their macro level data across numerous metrics is very revealing: They focus on what they know.
Their business grows linearly and proportionally, setting it apart from many other Low Fare Airlines.
That they stick to what they know may be part of the reason for their success. Not only have they grown, they have preserved operating margin in a business notoriously harsh on the incumbents.
That they would, in the part of the business cycle we are currently in, consider changing substantively their model is simply not consistent with their observed performance and thus success.
