When you’re spending a lot of your money to move quickly from one place to another – especially if you’re trying to start a much-needed vacation – you want things to go well. Airline companies provide a valuable service, but things don’t always go as planned. And based on customer complaints, issues seem to spring up in some flight providers more than others.
While almost every airline in the US had a higher customer satisfaction index in 2023 than in 2022, complaints still piled up. Is the rising number of negative airline reviews a reflection of service? Or is it simply a misunderstanding?
We made the list from the worst to best airlines in the United States to find the answer based on real customer reviews.
- Most airline reviews reveal issues with extra fees, rude customer service representatives, and delayed or canceled flights.
- Based on customer reports on PissedConsumer.com, Delta Airlines, Allegiant Air, and Frontier Airlines are reported to have caused the highest losses among US airlines, at $2.7 million, $2.1 million, and $1.5 million, respectively.
- Delta Airlines and Frontier Airlines customers reported the most resolved issues, while Sun Country and Alaska Airlines clients stated the fewest.
10. Frontier Airlines: The Worst Airline I’ve Ever Flown
Frontier Airlines Rating* – 1.5⭐⭐
Frontier Airlines Reviews – 3.9K
Resolved Issues – 29
According to consumer complaints in 2022, Frontier Airlines ranks first among airlines in the U.S. by the number of negative reviews, which gives reason to consider it one of the worst airlines. So, what is Frontier Airlines rating among other U.S. airline rankings based on customer reviews left on PissedConsumer?
Frontier Airlines rating
The Frontier Airlines rating is 1.5 stars out of a possible 5 based on 1860 online reviews. Currently, only 6% of customers in these reviews would recommend Frontier, which is not surprising since 89% of Frontier Airlines reviews are negative.
What are the top concerns highlighted in Frontier Airlines reviews?
Among the top Frontier Airline complaints, customers discuss poor communication with customer service, uncomfortable seating, and delayed flights. Hostile employees and deceptive practices have also worried travelers.
Despite the staggering number of more than 340,000 calls made to the airline via the PissedConsumer platform, only 4% of the customers could successfully resolve their issues.
One frustrated customer complained about a canceled flight, leading to a lost job opportunity. To add insult to injury, the airline only credited her $100 for a $449 ticket, leading to a monetary loss on the ticket and the potential job.
Another Frontier Airline client called the company “the worst airline I’ve ever flown” after their flight was “delayed by over 4 hours.” The online app and kiosks wouldn’t “work to let me add and pay for my bag on my way to San Diego,” and when they “approached customer service, they wanted to charge me $20 to help.” Overall, the reviewer concluded:
The flight attendant was super rude to both of the people in my row. I went 7 hours without food or anything to drink. The entire experience was horrible.
9. Spirit Airlines: Worst Airlines with Lousy Customer Service
Spirit Airlines Rating* – 1.7⭐⭐
Spirit Airlines Reviews – 2.1K
Resolved Issues – 14
Like Frontier Airlines, Spirit Airlines is an ultra-low-cost carrier, which means there are no frills for customers. Perhaps this lack of amenities is why Spirit Airlines is near the top of our list of most complained-about airlines. So, where does Spirit Airlines rate against other US airline rankings?
Spirit Airlines rating
Spirit Airline reviews have left the company with a rating of 1.4 stars out of a possible 5 on PissedConsumer. Just 17% of reviewers would likely recommend Spirit Airlines to a friend or colleague. While customers praise the company for cheap flights, they find the customer service to be lacking.
What are the top concerns highlighted in Spirit Airlines reviews?
As a budget-friendly airline, Spirit Airlines doesn't offer many frills, which can cause concern for customers looking for cheap tickets. Customers complain about a lack of customer service, a bad refund policy, bad seats, and extra fees. They also have expressed frustration with a lack of professionalism, poor compensation when problems arise, and rude and disrespectful behavior.
Besides, when attempting to contact the airline, customers also have trouble. On average, customer calls last for 5 minutes and 41 seconds, with only 9% of the raised issues resolved among 15,800 calls.
In one Spirit Airlines complaint, a flight was delayed by more than 9 hours. According to the reviewer:
Customers were so angry with the gate agents and Spirit for the delays, lack of communication and overall attitude that local police were brought to the gate to supervise Spirit's shenanigans.

One American Airlines customer flies “internationally all the time” and has “never had a worse experience than with American Airlines.” Their issues stemmed from a canceled flight, a voucher for compensation, and more than “7 hours with customer service talking to agents, supervisors, and customer relations trying to get them to correct the error.” Finally, the customer stated:
Never ever use Airline Airline if you can avoid it as they have absolutely no regard for their customers. To compensate me for over $3,000 in additional costs I am facing directly because of them, they credited me 2,500 miles.

One Alaska Airlines customer experienced issues with the business practices firsthand when they were charged twice for one of their tickets:

How to Choose the Right Airline
Nobody wants to feel foolish or, worse, furious when trying to get from one place to another. Choosing the right airline is the first step to a smooth vacation or work trip.
Consider the style of travel
There are several types of airline companies. Low or no-frills companies will have lower prices but won’t offer much in the way of comfort or luggage features. Airlines with open seating may not be ideal for families traveling together. Be sure to get the style of plane that best suits your needs.
Learn from others who have had great experiences, and especially those who have had rotten ones. Real customer reviews will always give you great insight into how a company works.
Use comparison tools
There are many websites and comparison tools online to help sort through the many options when it comes to flights. Shift your plans a few hours or a few days to see the price difference. Check for baggage options and seating preferences. Play with the options to be sure you’re getting what you need when needed.
When Airlines Get It Right…And When They Get It Wrong
While it would be ideal that every airplane trip goes smoothly without any issues, the reality is that things will go wrong. The real test is how well the airline handles the issues, smooths over the bumps, and ensures that all the customers get where they need to be. Have a great airline story to share? Or perhaps you’re still sorting out an air travel nightmare? You may write a review to share your experience with others.
