United Airlines will be solidly profitable this year even if oil stays at 90-110, because of strong demand, resilient consumers, and cost recovery measures. The company is investing heavily in product and technology, giving it a competitive edge over rivals who are losing money at these oil levels.
Oil prices will stay elevated in the 90-110 range for the indefinite future because the straits are unlikely to open sustainably, and the dynamics make a sustained decline hard to see. This is higher for longer than most expect.
