Will Delta's main cabin RASM turn positive YoY by Q2 2026?

The market asks whether main cabin RASM turns positive YoY by Q2 2026 — and it already HAS in Q1. The question is whether it sustains into Q2. Multiple forces support continuation: (1) Delta is cutting capacity meaningfully with 'downward bias', directly supporting RASM; (2) fuel at $4.30/gal forces industry-wide pricing discipline — competitors cannot sustain below-cost fares; (3) Bastian expects fuel to force structural rationalization/consolidation, reducing industry supply; (4) main cabin demand is healthy with cash sales up double digits. The only risk is a severe macro demand shock from tariff escalation, but even then, capacity cuts offset demand weakness on a per-unit basis. 92% probability.

Main cabin RASM inflection is a structural shift, not a one-quarter anomaly. The drivers: (1) revenue segmentation rollout (basic vs. preferred vs. premium main cabin) creates upsell opportunities; (2) competitor capacity discipline — multiple airlines pulling back; (3) YoY comp gets easier as 2025 main cabin RASM was negative; (4) fuel recapture flows partly through fare increases. The risk scenario is a tariff-induced recession that crushes leisure demand specifically in main cabin (premium is more insulated). But even a 5-10% demand decline would likely be offset by the meaningful capacity cuts Delta is implementing. Resolution requires only Q2 positive, and the Q1 positive reading gives a strong foundation. 90%.

The resolution criteria is 'by Q2 2026' which likely means achieving positive main cabin RASM in either Q1 or Q2. Since Q1 is already confirmed positive, this may already be resolved YES depending on exact resolution language. Even interpreting strictly as 'Q2 must be positive', the setup is extremely favorable: flat capacity with low-teens revenue growth guidance implies significant unit revenue improvement. Joe Esposito specifically called out strength in 'both premium and main cabin.' The industry backdrop (fuel-driven consolidation pressure, competitor pullbacks) structurally supports pricing power. Only a severe, rapid demand shock could reverse this within a single quarter. 91%.
