How Flying by Plane Will Change in 2026 for US Travelers

Airlines are increasingly shifting their strategies toward premium travelers, responding to higher margins in business and first-class cabins.

American Airlines highlighted this shift in December 2025, when it announced a major fleet overhaul. All newly delivered widebody aircraft, including Boeing 787s and A321XLRs, will feature lie-flat suites, enhanced privacy, upgraded dining options, and premium beverages, such as Bollinger champagne. 

Other US carriers have been following a similar path. United Airlines has expanded its Polaris business-class offering, while Delta Air Lines continues to invest heavily in its Delta One cabins. Even Southwest Airlines, long known for its simple low-cost approach, has said it is exploring a first-class-style product.

This premium push is driven by changing revenue dynamics. Airlines report that business- and first-class tickets now account for a significantly larger share of total revenue than before the pandemic. Delta, for example, has stated that premium products now generate more than half of its total revenue.

This shift means travelers can expect more premium cabin options and upgraded onboard experiences, while airlines increasingly lean on higher-paying customers to grow revenue.

Airlines are expanding both seat capacity and route networks to keep up with strong travel demand. 

In the US, carriers reached record capacity levels in late 2025. Industry data shows that airlines scheduled 271 million domestic seats in the fourth quarter of 2025, a 2 percent increase from the same period a year earlier, making it the busiest fourth quarter on record. That growth is expected to continue with an additional about 2.9 percent capacity increase in the first quarter of 2026.

Chicago provides a clear example of this expansion. American Airlines has announced its largest-ever schedule at Chicago O'Hare for summer 2026, adding 100 daily flights and bringing the total to 550. United Airlines is also scaling up operations at the airport, with plans to operate about 750 daily flights from O'Hare in summer 2026.

Travelers will see more flight options, particularly across high-demand corridors such as US-Europe and US-Latin America.

Airport security screening in 2026 looks noticeably different from what travelers experienced in 2025, as the Transportation Security Administration (TSA) rolled out new identity verification rules and expanded the use of biometric technology across US airports.

One of the most impactful changes took effect on February 1, 2026. The TSA introduced a $45 Confirm ID fee for travelers who arrive at domestic security checkpoints without a REAL ID-compliant driver’s license, a passport, or another approved form of identification. The fee is designed to offset the additional time and resources required to manually verify a traveler’s identity.

Additionally, the TSA is expanding its PreCheck Touchless ID system, which uses facial recognition to verify a traveler’s identity without requiring a physical ID. This option is being expanded to 50 more airports from 15 current hubs. 

Eligible travelers can opt in ahead of time through the TSA PreCheck program and participating airline apps, including Alaska, American, Delta, Southwest, and United.

Flying is expected to become safer and smoother in 2026 thanks to investments in new technologies, stricter oversight, and the Federal Aviation Administration (FAA) overhaul.

The FAA plans to modernize flight information management and aircraft movement between controlled facilities, addressing weaknesses exposed during the latest 43-day-long government shutdown, which caused nationwide delays and cancellations.

Transportation Secretary Sean Duffy said the US would need an additional $19 billion to fully fund the overhaul, building on the $12.5 billion already approved through the Big Beautiful Bill. This investment aims to replace decades-old equipment, hire more controllers, and strengthen aviation safety.

Key elements of the modernization include:

• Advanced radar tools, improved communication networks, and automated data-sharing platforms.

• A centralized Aviation Safety Management System (SMS) office to unify safety processes previously split across five units.

• An Airspace Modernization office to install a new air traffic control system.

• Consolidation of finance, IT, and HR departments under the Office of Administration and Finance to reduce redundancy.

Once implemented, these upgrades are expected to reduce delays and disruptions during busy periods, improve emergency response, and support Flight Plan 2026, which is the FAA’s strategy emphasizing three pillars: people, safety, and modernization of the National Airspace System.

In 2026, travelers will see that AI is now being embedded at every stage of the journey.

Conversational AI tools are becoming more common, allowing travelers to simply describe what they’re looking for in natural language and receive customized trip plans in return.   

American and Alaska Airlines, for example, have introduced AI planning tools that let customers type a prompt like “ski trip in February” and get destination ideas and flight options based on real-time fares. 

At the same time, OpenAI now allows companies, including travel brands, to build chat-native apps that plug their services directly into ChatGPT conversations, allowing travelers to search for flights and receive personalized recommendations within a chat. Virgin Australia has already partnered with OpenAI, and we can expect US carriers to follow in 2026. 

US airlines are also using AI to enhance customer support. United Airlines recently updated its mobile app, embedding AI across multiple touchpoints, including boarding assistance, disruption management, personalized notifications, and real-time travel guidance. 

Together, these developments point to a future where AI is not only common but expected by travelers at almost every step of their trip.

Passengers may not notice the difference day to day, but aviation is steadily moving toward more sustainable operations. Late 2025 brought a wave of announcements focused on sustainable aviation fuel (SAF) and new investments to support its adoption.

In October 2025, United Airlines increased its SAF supply through a partnership with Neste, becoming the first commercial airline to purchase SAF for use at three major US hubs: Houston–Bush (IAH), Newark (EWR), and Dulles (IAD). 

Across the industry, Airlines for America (A4A) and government partners have set a goal of making 3 billion gallons of cost-competitive SAF available by 2030.

Airlines are also encouraging travelers to participate in these efforts. In December 2025, Alaska Airlines offered loyalty members a 500-point bonus for every $100 contributed to support SAF-related projects.
