Airline reviews

The entire travel day was a disaster from beginning to end. Woke up at two in the morning to make it to San Juan airport in time for a 5:30 am flight to Milwaukee which connected in Baltimore. Massive delays lead to me missing original connection out of Baltimore. Sixteen hours of delays/rebooking/layover time later, arrived in Milwaukee to find that only one of two checked bags made it there (despite the fact that Southwest brought another 737 jet to San Juan to fly us out to our original Baltimore connection—-not squeezed into another booked flight). The flight from Baltimore to Milwaukee was barely half full, so there was no logical reason to ship my bags out of Baltimore on a different flight to Chicago to then ship to Milwaukee. Southwest decided that my bags should not have been on the same connecting flight I WAS ON to Milwaukee, and then proceeded to accidentally leave my larger bag with the important items in Chicago. Terrible logic and support all around. Extremely angered and disappointed with SW. What a clownish operation your company has become!

Love them will get a Southwest card to track my points and keep flying with them. My family and I were pleased with the services.

It was canceled. Supposedly weather. But there was no snow in Baltimore. At least we found out before driving to airport

WIFI was great. My selection for seating is an aisle, but during my trip, I never had an aisle seat. If we can get that corrected, I will be thrilled. No snack or drink on this flight.

The seats were comfortable, and the boarding process was pretty smooth.

The crew canceled the complementary snack and drink in anticipation of turbulence that never materialized. I was counting on the drink (water) to take the the doses of medication - prescribed for my heart condition - that were due during the flight. Since no snack or meal was served on this flight, I cannot rate the food quality. Otherwise, this flight was excellent.

Flight was fine other than there was a gate change that I was not notified of. By chance I happened to check my phone and saw the change, otherwise, we would have missed our connecting flight.

Southwest like most American domestic airlines, is a mediocre airline. But it is among the cheapest. Oh well.

Other than a bit of a delay, everything was good. Again, the boarding process and picking seats is the only thing I don't enjoy.

The quality of Southwest Airlines continues to degrade each time I fly with them. If it were not for the free luggage, I would probably choose another airline. Their prices are a little bit competitive, but way too high for the quality of the service. Southwest is not unique in this way. Domestic flight in the United States of America has continued to be a lower and lower quality product. Very sad when you compare the quality of domestic airlines to that of many international airlines around the world.

Flight was delayed for about an hour but overall good experience

Delta staff was exceptionally helpful and considerate. However, the first two of three flight legs were delayed making connections tentative and stressful.

Delta is always late. Ruined our first day of a short vacation. Timing is important. We pay to stay on an itinerary

First flight was delayed which resulted in missing our connecting. As a result class was downgraded to economy on a later flight.

Seats were not bad enough and uncomfortable good legroom in the emergency exit row we were in, but we were forbidden to hold my grandson on my lap for a little while, and the stewardess passed us saying it was against regulations which makes little or no sense when you’re 36,000 feet. The food snacks were really bad. Tasteless tasted like wallpaper, but we’re supposed to be protein bars, and the announcements were all completely incoherent because of the noise of the airplane and the lowness and crackly nature of the PA system.. this was disgraceful. No one in our party could understand a word of what the captain or the flight attendant were saying —not a word! The landing was a little hairy in a pretty stiff crosswind -we bounced before the plane stabilized on the runway

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

My sister and I paid to have our seats and have them next to each other. I heard one of the employees say to the other one that you shouldn’t have given away reserved seats away to other passengers, and so I guess that is what happened because I got the last most uncomfortable seat in the plane even though I paid to sit in the middle of the plane with my sister. Terrible Experience !!

We checked one bag. That was fast and the agent was fast and super nice. At the gate, boarding was fast and efficient. Flight was uneventful which was great because it was early in the morning and most folks were sleeping. Landing was great. Delta does a really good job of making the flying experience better all around considering you are sitting in such a small space on a plane for several hours.

One of the best crews and best flights I’ve ever had! Really great experience

The bus ride from the terminal to board the plane is uncomfortable and stressful when making a connection.

Great experience, boarding was fast and efficient, so much so that we arrived to Chicago very early

The seats were uncomfortable, as if the cushions haven't been switched out in many years. I felt like I was on an old bus. The food was delicious. thank you. Onboard entertainment, very limited. Unless you like violent movies. Why in the world would you have such severely violent movies on a plane? if you don't want to see such things, you don't have a choice. Have you considered that when choosing entertainment? Good god. Why would you have the Godfather? Or black women being brutally beaten with a club? Why in the hell would you put that kind of material on a plane? As for Kayak: Why when I ordered Qantas, was the plane on United?

Very comfortable flight, snacks and drinks were good, good communication from crew. Could have used a little more information on timing of boarding for group 5

I will never fly ANA again. They lost one of my large pieces of checked luggage, the heaviest one with the most valuable items in it, and they said they will not send me an email unless they can't find it, even though the paper they gave me to track the status of my lost luggage requires a code from an email they are supposed to send me so I can do baggage tracing. They claim to be an international airline, but they also insist on calling a Japanese telephone number to confirm where to send the lost baggage if they find it. It is impossible to find an actual contact email address for customer support on their website, and their AI chatbot is unhelpful, directing you to a webpage that says it is for contact information but does not have any actual email addresses or phone numbers listed on it. My seat in economy did not recline at all, even though I was not sitting in an exit row nor the very back row. I had to sit in the fully upright position for over ten hours of international travel. Awful experience overall.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Miserable. Active military on orders turned away from Lounge because not in uniform. This is completely contrary to United’s online lounge access policy. Sad that employees aren’t trained better. This is not the United Airlines my parents used to regularly fly with.

Both flights were fine. I wish there was a little more legroom, but we got to where we needed to be on time, the crew did their job, and that’s really all that matters. We’ll fly United again.

Crew was unhelpful in boarding. Did not help passengers board and store bags efficiently. Did not alleviate tensions as passengers had to stow bags then return forward to seats. Baggage rules are unreasonable. Will fly southwest next time

On time from BWI to IAH but delayed over an hour from IAH to AUS without reason.

The overall service, quality, and price-point value for USA domestic flights is quite poor. If there were other options, I would take them.

The ground closures and flight delays were unwelcome. I think the captain did what he could to manage expectations for the delays, but the stress level increasing in the cabin was palpable with every announcement. It may be obvious to those who fly frequently, but if the ground is closed for us to get to a gate, it's also closed for connecting flights to leave. Other passengers were so stressed they were rude. A bit further explanation could have helped.

Horrible. No AC. No Air inside the plane. We had to deplane twice! It is late almost 5 hrs in total. I almost passed out and about to call 911. I asked the crew to be honest and open the door. The lady next to me was lay down in the floor due to heat and no air inside the plane. I got headaches, can’t wait the replacement flight about midnight Dallas time. I end it up rebook for next day flight and stay overnight using my own pocket in a hotel nearby due to headaches and can’t breath. I still have a headache this morning. Still not decided yes how to file this issue to AA and/or FAA.

They have overselled the ticket and kicked me out from boarding, All my Plans were collapsed and important network meeting missed.also I booked direct flight i have to go through an 1 stop and it was frustrated.

Flight was delayed for 5 hours in ten minute increments. Bizarre and frustrating

Patrons with larger bags were asked to check the bags when boarding. Seems like the most effective, and least costly way, way to successfully use the cramped space.

I would like a refund for the extra cost the seat I paid for. An oversized person sat next to me and I couldn’t fit on my seat and had to move to another seat.

Kayak boarding information contained inaccuracies that would have not existed if booked directly with American. Paid for preferential boarding, was last to board.

You were more on time than United. I'm so over united delays.

great experience. minimal lines at BWI. at DFW they got a long haul 787 boarded in 30 minutes

Late arrival flight arrived in BWI and I missed connecting flight in CLT to mobile. I had to wait 6.5 hours for next flight.
