Recap of the Most Recent Important Stories

1.  Delta reported second-quarter 2025 earnings (excluding $1.17 per share from non-recurring items) of $2.10 per share, which beat the Zacks Consensus Estimate of $2.04. Earnings decreased 11% on a year-over-year basis due to high labor costs.

Delta, currently carrying a Zack Rank #3 (Hold), expects third-quarter 2025 adjusted earnings per share in the $1.25-$1.75 band. The adjusted operating margin is expected in the 9-11% band. With air-travel demand stabilizing, revenues on an adjusted basis are expected to either remain flat or increase up to 4% from the third quarter of 2024 level.

United Airlines' second-quarter 2025 earnings per share (excluding 90 cents from non-recurring items) of $3.87 surpassed the Zacks Consensus Estimate by a penny but declined 6.5% on a year-over-year basis. Operating revenues of $15.2 billion fell short of the Zacks Consensus Estimate of $15.4 billion but increased 1.7% year over year.

For third-quarter 2025, UAL anticipates adjusted EPS between $2.25 and $2.75. For 2025, UAL expects adjusted EPS between $9.00 and $11.00. 

3. LATAM Airlines reported a 10.7% year-over-year increase in consolidated capacity, measured in available seat-kilometers (ASK). The uptick was driven by a 13.9% increase in LATAM Airlines Brazil’s domestic capacity, partly owing to the temporary closure of Salgado Filho International Airport in Porto Alegre during 2024, as well as a 12.3% increase in the group’s international capacity. LTM’s consolidated traffic, measured in revenue passenger-kilometers (RPK), increased 10.2% year over year. 

4. Copa Holdings reported robust traffic numbers for June 2025 on the back of upbeat air travel demand. Driven by high passenger volumes, revenue passenger miles (RPM: a measure of traffic) improved on a year-over-year basis in June. To match the demand swell, CPA is increasing its capacity. In June, available seat miles (ASM: a measure of capacity) increased 5.3% year over year. RPM rose 6.3% year over year. Since traffic outpaced capacity expansion, the load factor (the percentage of seats filled by passengers) inched up to 87.5% from 86.6% in June 2025.

5. In a bid to expand its network, Southwest Airlines announced that it will operate flights to St. Thomas in the U.S. Virgin Islands in 2026. St. Thomas has become a popular vacation destination, with a record number of airline passengers in 2024. St. Thomas is the first of three new destinations for 2026 that the carrier expects to announce this summer. It will be the ninth island destination served by Southwest in the Atlantic Basin. This is the first time since 2021 that LUV is adding new destinations to its network.

Amid the tariff-induced uncertainties, second-quarter 2025 earnings reports of many airlines are expected in the coming days. For example, Southwest Airlines is scheduled to report quarterly results on July 24. While improved air travel demand is likely to boost the top line, the bottom line is expected to have been aided by reduced fuel costs.
