Fleet and Route Network
United Airlines operates a global fleet of more than 900 aircraft, including widebodies like the Boeing 777 and 787 Dreamliner. It flies to six continents and offers one of the most extensive networks in the world. United’s strength lies in long-haul and hub-to-hub connectivity, especially from Chicago, Newark, San Francisco, and Houston.
Alaska Airlines, with around 320 aircraft, focuses mainly on North America , especially the U.S. West Coast, Mexico, Canada, and parts of Central America. Its partnership with oneworld airlines (including American Airlines and Japan Airlines) gives travelers solid international options, though not as broad as United’s Star Alliance access.
If your travel involves frequent long-haul or global destinations, United wins. For shorter routes or coastal flying, Alaska’s coverage is hard to beat.

Cabin Experience and Comfort
United Airlines
United offers multiple cabin tiers , Economy, Economy Plus, Premium Plus, and Polaris Business Class. Premium Plus features wider seats and better meals, while Polaris offers lie-flat beds and access to Polaris Lounges.
Seatback screens are available on most long-haul aircraft, though some domestic jets rely on streaming entertainment. Wi-Fi is standard fleetwide.
Alaska Airlines
Alaska’s First Class cabin features wider recliner seats (40” pitch), free meals on longer flights, and complimentary drinks. In economy, Alaska’s Premium Class provides up to four extra inches of legroom, priority boarding, and free drinks.
Most aircraft now feature seatback screens or streaming entertainment, and the service quality remains one of the best among U.S. airlines.
If you prioritize global business class amenities, United’s Polaris wins. For domestic comfort and service consistency, Alaska comes out ahead.
Loyalty Programs: MileagePlus vs Mileage Plan
United MileagePlus
MileagePlus remains one of the most versatile programs in the world, offering Star Alliance award redemptions, upgrades with PlusPoints, and strong elite tiers (Premier Silver through 1K). United miles are easy to earn through Chase Ultimate Rewards transfers and co-branded cards.
Alaska Mileage Plan
Alaska’s loyalty program still uses distance-based earning for most fares, a major advantage for frequent long-haul flyers. Its oneworld partnerships allow redemption on top-tier airlines like Qatar Airways and Cathay Pacific.
Mileage Plan miles often deliver higher redemption value than United’s dynamic pricing, especially for premium partner awards.
If you want maximum global reach and upgrade flexibility, MileagePlus is stronger. If you value award value and oneworld redemptions, Alaska’s program wins.

Pricing and Fees
Both airlines follow competitive pricing structures on domestic routes, but Alaska tends to have simpler fare bundles and fewer add-on fees.
| Feature | United Airlines | Alaska Airlines |
| Carry-on in Basic Economy | Allowed (since 2024) | Always allowed |
| Change fees | None (most fares) | None |

Onboard Service and Dining
Alaska Airlines continues to outperform most major U.S. airlines in customer satisfaction surveys, ranking high for friendliness and reliability.
United’s service has improved substantially, particularly in Polaris and Premium Plus cabins, with better catering and amenity kits. However, feedback for domestic economy still varies depending on route and crew.
For a premium domestic experience, Alaska’s consistent service gives it an edge. For international premium cabins, United’s Polaris is clearly superior.
Reliability and Operations
Both airlines have strong operational records, but Alaska often leads in on-time arrivals and fewer cancellations. United’s scale means it handles more global complexity, which sometimes results in delays or re-routings.
Alaska’s smaller network allows for smoother day-to-day operations, particularly on domestic routes.

If you’re a frequent flyer who values global upgrades, alliance access, and premium business cabins , United Airlines is your airline.
If you prioritize service, reliability, and a seamless U.S. flying experience , Alaska Airlines wins for domestic travelers.
