Top 5 US Airlines for Economy Class on Domestic Flights

In 2024, US airlines carried a record 852.1 million passengers on domestic flights, up from 819.3 million in the previous year. To meet this growing demand, some airlines have stepped up their game by:

Adding more flights and new routes
Investing in newer, more efficient, and comfortable aircraft
Implementing advanced technologies
Enhancing health and safety measures with rigorous cleaning protocols
Improving customer service through better staff training

But what about cheap domestic flights and affordable domestic airline tickets? As airlines expand domestic capacity and compete more aggressively on popular routes, travelers can still find good-value fares, especially when booking early or staying flexible with dates.

Fuel prices remain volatile but strong competition and frequent fare sales keep many domestic routes reasonably priced. Flexible booking policies and dynamic pricing also help budget-conscious travelers save.

With dozens of carriers operating in the US, it can be challenging to identify the best domestic airlines. To assist you, we’ve compiled a list of the top US domestic airlines for economy class, based on domestic airline ratings 2023/2024/2025 and customer reviews.

1. What Is the Best Domestic Airline? Please Welcome Delta Air Lines!

Why Delta Nailed It:

In addition to the image above:

Delta earned the Best Airline Entertainment award in the 2025 Rolling Stone Travel Awards, praised for its top-tier content and wide variety of options for every traveler.
Delta placed No. 10 on Forbes’ second annual Most Trusted Companies in America list, ranking among 300 organizations recognized for earning strong consumer trust.
For the seventh year in a row, The Points Guy named Delta the best US airline, citing strong 2024 performance across reliability, customer experience, costs and network, and loyalty.

Vital Facts:

Domestic Network: Delta boasts one of the most comprehensive domestic networks in the US, facilitated by its nine major hubs. These hubs are strategically located in Atlanta (ATL), Boston (BOS), Detroit (DTW), Los Angeles (LAX), Minneapolis-St. Paul (MSP), New York (JFK), New York (LGA), Salt Lake City (SLC), and Seattle (SEA). This extensive network enables Delta to offer broad destination coverage across the country.
Fleet Upgrades: Delta’s early-2024 order of 43 Airbus aircraft has since progressed, with many of those jets already delivered or in active delivery as of late 2025. The A220-300 fleet has continued to grow beyond the original nine aircraft. This helps to support Delta’s broader fleet renewal rather than solely replace the now-retired 737-700s.
Tech Innovation: Delta’s digital identity program has expanded through 2025. Facial recognition and mobile ID options are now available at more major hubs. Pandemic-era tools like digital health passports are no longer in use, and the focus has shifted to streamlined security, touchless check-in, and integrated TSA PreCheck digital ID features.

Economy Flight Types Offered: Delta offers three seat categories on domestic routes: Basic Economy, Main Cabin, and Delta Comfort+. Comfort+ is treated as an enhanced seating option within the Main Cabin rather than a separate fare class, giving travelers extra legroom and earlier boarding.

Which Flight Type to Choose: Your choice depends on budget and comfort preferences, but Basic Economy remains the most restrictive. You can’t choose your seat in advance and are often assigned a middle seat. Basic Economy now earns SkyMiles and MQDs, but it still lacks flexibility and amenities compared with Main Cabin and Comfort+.

Reliability: Southwest’s operational performance has strengthened. In Condé Nast Traveler’s 2025 Readers’ Choice Awards, the airline ranked No. 9 among the best US airlines. This reflects improvements in both reliability and overall travel experience.
Customer Satisfaction: Southwest ranked third in The Points Guy’s Best Airlines Report 2025, jumping two spots from last year thanks to strong value, customer-friendly policies, and dependable service. It also ranks highest in customer satisfaction in the economy/basic economy segment for the fourth year in a row, according to J.D. Power’s 2025 study.

Domestic Network: Southwest serves more than 120 destinations across the US, Caribbean, Mexico, and Central America. This gives travelers broad domestic and near-international coverage. The airline still uses a point-to-point model. But major cities like Denver, Chicago Midway, Baltimore, Phoenix, and Las Vegas now function as de facto hubs due to their large flight volumes.
Fleet Upgrades: Southwest’s fleet strategy through 2024 and 2025 centers on expanding and modernizing its Boeing 737 MAX fleet. However, deliveries of the MAX 7 continue to face certification delays. The airline remains committed to the model, with hundreds of aircraft on order and deliveries expected to accelerate once approvals are finalized.
Tech Advancements: Southwest has continued upgrading its digital tools. This includes app-based same-day standby, faster onboard Wi-Fi on more aircraft, and ongoing technology modernization efforts that streamline check-in, rebooking, and day-of-travel updates.

Economy Flight Types Offered: Southwest doesn’t differentiate its seats into first class, premium economy, or economy. Instead, it offers four fare types: Wanna Get Away, Wanna Get Away Plus, Anytime, and Business Select. These fare types cater to different needs and budgets while providing the same seating throughout the plane.

Which Flight Type to Choose: Each fare type offers different flexibility and earning potential. Wanna Get Away fares are the most affordable. Wanna Get Away Plus adds same-day confirmed changes and standby access. Anytime and Business Select fares provide the most flexibility, including full refunds to the original form of payment, higher points earning, and priority benefits. Your choice depends on how much flexibility and convenience you need for your trip.
