If they're going to Europe, they're having to avoid about 4 hours of airspace... And you have the surging fuel prices. Airlines operate on razor-thin margins. The simultaneous combination of spiking jet fuel costs and massive operational inefficiencies (flying 4 extra hours requires more fuel, reduces aircraft utilization, and increases crew costs) will obliterate profitability for international carriers. SHORT. The aviation industry cannot pass 100% of these extreme cost increases onto consumers without destroying demand, leading to inevitable earnings misses. Governments could step in with fuel subsidies for national carriers, or airlines successfully pass all costs to consumers without a drop in booking volumes.
