Key insights
- Airline stocks AAL, UAL, and DAL are selling off despite differing risk profiles. Rising fuel costs are a major headwind, with UAL offsetting costs through increased fares due to record bookings. AAL's negative book value makes it more vulnerable. The market is pricing in a potential permanent impairment or temporary cost shock, raising questions about which airlines are truly impaired versus caught in the broader selloff.
UAL and AAL are both down hard this week. One has negative book value and razor thin margins. The other just set a bookings record and trades at 8.7x forward earnings.
The market sold them both the same way.
Fuel costs have nearly doubled since the end of February. $100 oil is a real problem for any airline and nobody is pretending otherwise. Neither UAL nor AAL hedges fuel costs which means both are taking the full hit on the cost side.
But the first 10 weeks of 2026 were the largest booking weeks in United’s history. Fares booked last week jumped 15% to 20%. CEO Scott Kirby thinks United can fully offset the fuel cost increase through higher fares. The revenue environment is doing work that the balance sheet doesn’t have to.
AAL doesn’t have that cushion. Negative book value and almost no margin going into the same shock. That’s a completely different situation.
Delta went into this owning the Trainer refinery. Structural hedge that doesn’t care where spot oil trades. Still got sold off alongside everyone else.
Three airlines. Three completely different risk profiles. One indiscriminate selloff that priced them all the same way.
At 8.7x forward earnings with record bookings the question isn’t whether UAL has a problem right now. The question is whether the market is pricing a permanent impairment or a temporary cost shock on a business with the balance sheet to absorb it.
Which airline in this selloff do you think is actually impaired versus just caught in the blast radius?
