United Airlines receives first GTF Advantage-powered A321XLR from RTX's Pratt & Whitney

United Airlines has received its first Airbus A321XLR aircraft powered by Pratt & Whitney's GTF Advantage engines, marking the inaugural delivery of this enhanced engine variant. The GTF Advantage offers up to twice the operational lifespan of current GTF engines and provides 4-8% more takeoff thrust, enabling extended range capabilities. The engine features an advanced hot section design and remains fully compatible with existing GTF models, simplifying fleet operations. Pratt & Whitney, an RTX business, plans to transition its entire PW1100G-JM production line to the Advantage specification by 2028. Current GTF operators will be able to access 90-95% of the Advantage's durability improvements through a Hot Section Plus upgrade option, available from early next year during scheduled maintenance visits.

United trades at forward P/E of 11 as US airfares jump 25.5% and CEO predicts more rises

US airline fares rose 25.5% year over year in July, and United Airlines CEO Scott Kirby expects further gradual increases through the first half of 2027 if demand holds. United's second-quarter revenue reached $17.67 billion, up 16% year over year. Despite industry-wide fare growth, United shares have gained only 2.69% year to date, compared with Delta's 20.64% rise. United trades at a forward price-to-earnings ratio of 11, versus Delta's 13. Kirby framed the fare increases as structural catch-up, noting airport fees have risen roughly 60% since COVID and maintenance costs remain elevated. He told investors that airfares are still 13% below 2019 levels in real terms.
