I agree with your reasoning and I'm surprised that companies like Southwest seem to aim for monoculture.
... unless the risk and cost model they're looking at is that having multiple planes in the fleet increases the risk that spare parts are depleted for a particular model, ground crews aren't sufficiently cross-trained and errors on their part make flights less safe on average than in a monoculture, etc.
- notahacker 8y agoIt's less an operational risk calculation and more an operational cost calculation. It's entirely possible (and for airlines operating a wide variety of different length routes, entirely necessary) to safely operate a wide variety of airframes, but it does entail paying for a lot more redundancy.
