United Airlines' weak Q4 earnings outlook is driven by its higher fuel-price assumption, supporting the case for buying through temporary fuel pressure. United guided to $0.50-$1.50 in EPS using $4.80 per gallon; its disclosure says consensus assumes $4.35, a difference worth about $1.00 in quarterly EPS. x.com

Delta, United and Alaska should see margin expansion as the US-Iran deal and the lifted Hormuz naval blockade push oil lower into summer travel season. Crude fell from $92.16 on June 1 to $70.24, and fuel was 17–21% of their FY2025 opex; Alaska is the highest-beta name, with each $0.10/gallon move worth about $0.75 of EPS.

Higher transport and input costs threaten US stock margins and demand. The PPI surprise shows the oil-cost pressure described in March playing out: headline rose 1.3% monthly versus 0.6% expected, and core 0.7% versus 0.3%. The March scenario put logistics costs at 3-6 weeks and consumer prices and weaker demand at 1-3 months; margins could shrink 100-300 basis points if costs cannot be passed on. The full scenario was not expected to play out. x.com  x.com
