Consumer Reports recently asked readers to rate the 11 largest domestic airlines, on everything from pricing and delays to seating and service.

Out of a possible 100, here are the scores — from best to worst. Which U.S. airline do you think landed on the bottom? Later, we'll look at the 10 worst international carriers.

1. Southwest Airlines

Southwest scores high for on-time flights, service and pricing.

Score: 85/100

Southwest's score amounts to a grade of A. The teacher’s pet of airlines is said to have the shortest delay times, which is obviously a big deal for harried air travelers.

Plus, Southwest is the only one of the 11 carriers on this list to earn top marks for pricing transparency, including its lack of a fee for making ticket changes.

The airline also rates as one that consistently provides exceptional customer service — and if all this weren’t enought, Southwest allows you to check two bags for free. Swoon.

2. Alaska Airlines

Score: 84/100

Alaska Airlines is another star performer with high ratings in nearly all categories in the survey. From easy check-ins to excellent customer service, this airline pleased passengers across all ticket classes.

Alaska also was rated highly for its honest and transparent pricing during booking — and in the age of nickel-and-dime airline fees, this is a major selling point.

For high-end comfort, Alaska Airlines shared the top-spot with Hawaiian Airlines, based on responses from travelers who took more than 8,700 flights in premium seating.
