The naked truth is this. Skywest has a very cheap cost basis, especially with modular rate structure they offer delta for many cities out west. Mod rates change under variable conditions. What’s this mean? It means they don’t have a CPA and it’s much cheaper. That plus they fly the better plane makes 9E growth questionable during inflation, market volatility and higher fuel prices. Then there’s the A220 which changes the game completely. This thing burns 1600 a side fully loaded at Mach 0.79 at FL400. Short runways and steep approach angles. Delta may be in their 10,000th mind change, but doing the math, growth at 9E makes no bloody sense.
