My original flight was extremely delayed but I was able to join the standby list for an earlier flight. I was grateful for this feature but I wish I could’ve gotten my standby confirmation sooner.

I will be flying again Southwest Airlines. Friendly crew, comfortable and affordable.

Since the flight wasn’t full, we had some extra room. Crew was great

Tight seats. Be prepared to sit in the middle if you are in boarding group C.

Southwest has a serious issue with keeping their passengers in the dark about delays. They also appear to lack the necessary crews to deal with any sort of hiccup in their operations. The way they run their day-to-day operations is a joke. You are telling me that a hail storm in Denver, where hail storms are incredibly common, results in hours of delays due to every plane needing to be inspected for hail damage? Understandable, but there seems to be a skeleton crew of maintenance workers undergoing this daunting task. There was no particular order of inspecting planes, leading to some planes only having an hour delay or less in others having four or more just because of the luck of the draw of what plane got inspected with no consideration to how long the respective delay was. The entire time the passengers were told nothing except the fact that there was lightning in the area and the ground crews could not load the bags. This always happens that Southwest will incrementally delay a flight with no information given, leaving many frustrated passengers fuming once they find out that their flight is canceled. Don't make people wait around for hours at the airport giving them no information, just to keep them on the hook and prevent any action from being taken by the passengers in terms of finding alternate routes of transportation or accommodations for the night. How many hours of people's times do you think you waste by operating like this? How about having a fully staffed crew in one of your busiest hubs that is famous for severe weather that can effectively deal with a situation like this, or how about having planes on standby to quickly replace in case something like this happens, like all the other major airlines do. This is just like the Christmas fiasco but on a Denver scale, but again this is literally just from a single thunderstorm going over Denver in the spring. I'm glad I've stopped using Southwest as my primary airline and have switched to United. Every single time I fly Southwest, something has to come up. It's ridiculous and I seriously can't wait to finish using my miles so I don't have to deal with your garbage anymore. You used to be so good and I don't know why you thought you could just scrap your quality and expect people to deal with it. Oh, and I walked by someone getting CPR for over 5 minutes in the concourse. I hope he was ok. Southwest needs something similar.

Our first flight was so delayed that we had 10 mins to board the next one. We requested if the flight attendant could allow us off there plane first and they denied our request even though I have seen this done before. Luck was on our side that we didn’t miss our next flight.

Everything was great except for the in-flight wifi that wasn't working.

It was good. I wish you had gluten free snacks for my husband.

It was great! The new boeing has much more space and charging ports!

Flight had over 6 people in wheel chairs and there was only 1 gate agent. Very impressed though in how Maddie handled having to efficiency move that many people by herself. We still nursed in a timely manner.

Great. Flight departed early and arrived early. Deplaning and baggage claim ww were quick.

They separated our seats and moved us to the back of the plane. Hundreds of dollars and thousands of miles used and this was my platinum member experience.

AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.

Got on the plane and then needed to deboard the plane because they didn’t have any pilots?

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

First, the flight was schedule to leave at 12:08. Delayed to 12:38. It is 12:58 and I am sitting at the gate. The staff are not communicating with us (just tell me it’s gonna be five hours if that’s the case, quit hufflepuffing around like you’re trying to board us when the plane isn’t even here and you don’t know where your crew are. I’m still waiting for any communication about the further delay. This is a rebooked flight from a cancelled flight yesterday, when the airline failed to fulfill its fiduciary responsibility to hotel and cover transport for overnight cancelations. Asking about the food on the flight? What food?!? Delta doesn’t serve meals unless you pay for them and you really want me to give delta a high rating for passing out processed snacks (fun size!)? Can we be for real. Delta is cementing itself in history as one of the cheap, stingy, outdated, glory days are over airlines, and it shows. I took this flight knowing delta was going to provide below level service but this is beyond burgers!! I can’t believe a multi billion or dollar company looked straight in my eyes yesterday and I told me this wasn’t their fault and there for the extra cost in hotel and hundreds of dollars in Ubers are MY RESPONSIBILITY. The only thing I am at fault for is believing delta is reputable company worthy of my dollars. I’m not even sure I want to be compensated unless it is cash because I would rather die never traveling again than to put money in their pockets.

Rough day of travel all the way around. Wrong info given to us multiple times and mistakes in their booking making our trip 10 hours longer than planned. I’m bummed because I fly Delta all the time and love them. Mistakes happen. Just bummed that this was a rare trip our whole family was traveling together.

Meh. A late flight meant I missed my connections, and a 2pm LAX arrival turned into gettin in after midnight.

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Good even though flight was delayed, the crew was prompt and efficient.

No access to the Wi-Fi, noisy group of people made it difficult for me to hear through my earbuds. Snacks and drinks - limited service when your seat is at the back of the plane - people up front are always served first and the back gets whatever is left. Not pleased.

In this flight we had selected seating for our family in the middle of the plane in a 2x2 format. The airline changed them to the very back row of the plane and split them to 3x1. Why pay for seats that allow seat selection if the airline will just move them to the worst seats in the plane?

Never happened, because of the first delayed flight I lost the connection and had to wait overnight and take two flights to reach my destination.

The plane was delayed ~ 40 minutes. Communication could have been better. The entertainment was poor. We were not offered headsets by the flight attendants. The arm rest pad did not work properly, thus, I could not select what I wanted to watch.

A/C wasn't working. Made the 1.25 hour flight seem like 4 hours! Even at altitude it didn't cool down.

See my previous comments. I was probably booked in business but was moved to economy

No water on the toilets, dirty sits. 4 hours delayed departure.

East Lounge in Denver was terrible. Turning away active military on orders? Really? Sad.

The flight was delayed, but other than that everything was fine.

Baby cried a lot. Nothing anyone could do about it. Just part of flying.

For coast to coast travel the A321 and even the NEO, even in first class will never be excellent. That would take a B787 or 777 to accomplish.

The flight crew was fantastic! Which the seats had a small TV.

The foot ottoman cushion was missing on my business class seat.. the hydraulics is on its last leg & seat cushions do not have support or paddling. Heavily dented by butts

also wi-fi never worked attendant said satellite coverage is spotty over water ..... but we were over land!

I was unhappy with having the seat I chose changed at the last minute. I was moved to an aisle seat which did not recline and was next to the bathroom. The bathroom odors made the flight entirely unpleasant. Having carefully chosen my seat months before I was not pleased with my AA experience. In addition, they ran out of tea during flight service, really?

Dallas Hub. American taking ownership for their screwups instead of blaming their contractors and customers, trading their people, their call in service, reservation agents and their ticketing process. Make sure wheelchairs are available especially when the request is in their record.

The aircraft was on-time and plane and lavatory was clean.

Delay 14 hours! Missed all connections and had to fly different airline the next day.

Terrible customer service playing as usual was late and the Denver tried to get to a bus, but it already scheduled for service to Fort Collins, but because they could not help me at all at the baggage service desk. I missed the bus by one minute after they kept me arguing about how to handle my bag which have not gotten onto the carousel, Customer Service and Denver at the baggage claim customer service had the nerve to say she did not fly the plane and the responsibility of the bag was all mine. Pathetic.

Literally everything could have been better. Why are the planes always late?

Booked two aisle seats and were switched to an aisle and middle. Not happy.

I fly Frontier often and generally don't have any issues. For some reason, the Denver to Houston's George Bush Intercontinental (IAH) flight always needs to wait on the tarmac in Houston because a gate is not available after landing. I've been stuck for as little as 15 minutes and as much as a little over an hour. I know only fly the Frontier Denver to IAH route when there is not an available flight to Houston Hobby (HOU).

Gate agent for Frontier in Sioux Falls was horrible. Some people shouldn't have jobs where they need to work with people. This person tried to control everything and even argued with a Sheriff's Deputy. He seemed to write the law and think he was immune to everything and could do whatever he wanted. What a miserable experience for a lot of people. He even delayed the flight just for on his own actions. The pilots made up the time lost, but why does this person have this job. Apparently nobody cares at Frontier. We do, My wife said she would never fly on Frontier again.

Did not realize seats did not recline. Best to travel in an exit row... No question

Didn't like anything..entire crew was very rude to everyone on the flight. Plane old and the trays fall down on you the while time you're flying. Charged more for a carry on bag than for the plane ticket itself. Did make it from point a to point b, but worth the extra money to fly with another airline

9hrs delay and didn’t provided anything until after flight landed $75 voucher for fiuture travel no meals or anything.

My experience with frontier staff at the Denver airport was absolutely horrible. The manager on duty was even worst if was the worst experience I have ever had, I have never been treated so poorly as a customer in my life! The staff was extremely rude, eye rolls and attitude and then refusal to help me at all. I wish I could never fly frontier again that’s how horrible it was!

Fecal matter in seat back pocket. Presumably from a kids diaper.

I didn't get to do this flight l, hard to review
