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

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.
