American Airlines Group Inc. (NASDAQ:AAL) enters Monday with a potentially favorable revenue signal from Delta Air Lines Inc. (NYSE:DAL), but the profit picture remains clouded by surging jet fuel costs and geopolitical tensions. Delta reported second-quarter adjusted unit revenue growth of 12.4%, nearly three percentage points above the midpoint of American's own guidance. This suggests American's revenue target is within reach, but the airline still faces a challenging path to profitability.
American's last published June-quarter forecast calls for revenue growth of 13.5% to 16.5% on capacity growth of 4% to 6%. At the midpoints, this implies total unit revenue growth of about 9.5% — the revenue collected for each available seat flown one mile. Delta's strong result makes American's sales target look less demanding. However, American's adjusted earnings forecast, ranging from a 20-cent loss to a 20-cent profit per share, leaves far less room for comfort.
The key contrast lies in the conversion rate. Delta produced an 8.8% adjusted operating margin while paying almost the same fuel price American used in its forecast — about $3.93 per gallon versus American's assumed $4.00. American, by comparison, centered its per-share outlook at zero. The read-through is strong for fares, but not yet for earnings.
Friday's trading reflected this mixed message. American fell 0.64% to $16.95, but it outperformed Delta, which dropped 1.81%, and United Airlines Holdings Inc. (NASDAQ:UAL), which fell 2.36%. The S&P 500 rose 0.42%, showing the weakness was concentrated in airlines rather than the wider market. Over the past five days, all three carriers lost between 5.4% and 5.8%.
The longer trend is less kind to American. Delta's 2026 gain remains 15.35 percentage points larger than American's, evidence that investors still assign a premium to Delta's margins, balance sheet, and broader mix of high-return revenue from premium cabins, corporate travel, cargo, loyalty programs, and maintenance. TD Cowen analyst Tom Fitzgerald called Delta's post-results weakness a "buying opportunity," highlighting these diversified revenue streams.
The week ahead offers another check. United's second-quarter earnings call is scheduled for Thursday, July 16, at 10:30 a.m. EDT. A strong unit-revenue result from a second large network airline would make Delta's pricing signal harder to dismiss; a weaker figure would suggest Delta's premium-heavy business did more of the work.
American reports on July 23, with its call set for 7:30 a.m. CDT. Investors will focus on how much of the fuel increase it recovered through fares and fees. American previously said it was recouping close to half of the higher second-quarter fuel cost and forecast full-year adjusted results between a 40-cent loss and a $1.10 profit per share.
But the weekend may overwhelm the favorable revenue setup. Iran's Revolutionary Guards said Saturday that the Strait of Hormuz was closed until further notice, while U.S. President Donald Trump said Sunday it remained open to commercial traffic. U.S. spot jet fuel was already back above $3 a gallon on Friday, and Raymond James analyst Savanthi Syth noted that Delta's outlook used an earlier fuel curve, before the latest escalation. A sharp oil move could erase the benefit of higher fares before American reports.
For American shareholders, Monday's first signal is fuel, not bookings. Delta has made American's revenue hurdle look less demanding. American still has to show how much of that revenue it can keep.
