Looking for the best airlines in the US? Whether you care about comfort, affordability, rewards, or reliability, not all carriers deliver the same experience. Some shine in service, others in flexibility, and a few stand out simply for their sheer route network.
Here’s a breakdown of the top US airlines and what makes each one the “best” depending on your travel style.
How Are the Best Airlines in the US Ranked?
When comparing airlines, most travel experts and studies focus on:
- Reliability (on-time arrivals, cancellations, delays).
- Customer service and satisfaction.
- Comfort (legroom, Wi-Fi, snacks, entertainment).
- Rewards programs (miles earned, redemption options).
- Affordability and fees.
Sources like the U.S. DOT’s
Air Travel Consumer Report, J.D. Power surveys, and AirlineRatings often shape these rankings.
Real-world note: A business traveler may crown Delta the best for reliability, while a family might argue Southwest is the best because two checked bags fly free.
