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.

Excellent crew, free wi-fi, good experience. But we were in Row 30 and were song the sat called to board. It’s RIDICULOUS that the end of the plane would be among the last to board IT MAKES NO SENSE.

good food and service and the seats were much better than anything comparable provided by US airlines. The entire experience was light years better than flying with a US company.

This was my first time using Alaska. The best thing about Alaska is the people. Everyone that I had any contact with couldn’t have been better. So far on this trip no complaints. I will use Alaska again

My flight was delayed 2 hours which led me to lose my connection. As a consequence, I had to spend hours changing flights and hotel reservations to arrange my arrival to Vancouver.

Flight was great. Crew was excellent! Would fly with them anytime.

I liked the food. The WiFi was out and the flight was late.

Flight was late creating alot of stress getting to my connecting flight which was also delayed - fortunately worked in my favor, but made for a very late arrival time.

I encountered racist and discriminatory behavior by the Alaska Airlines staff on my recent trip from Baltimore to Vancouver with a connection in Seattle. After a power shutdown delayed our flight for several hours, there was a line of people formed who had connecting flights that they would miss. The Alaska airline representative in Baltimore handed out vouchers for all the white individuals and families in line and at the end of the line, a black woman and a brown man, separately, were denied vouchers for a hotel or a meal from the same representative and were told to rush to the airplane as we were clear to fly out. The representative in Baltimore assured them that Alaska airline representatives on the other side in Seattle would make sure they would have the vouchers for the night but as we arrived in Seattle around midnight, the Alaska airline representatives were incredibly rude to them and told them that by policy Alaska will not issue any vouchers for them and they remove responsibility for the delay. The two passengers of color separately explained that they saw other individuals and families receiving vouchers from Alaska Airlines for the same flight, and the Alaska Airlines representatives in Seattle accused them of lying. There is a legal case being brought against Alaska Airlines for this incident.

I miss my connected flight Baltimore to (Seattle). I was sitting on the Plane for 10-15 minutes. THE AIRLINES HAD TO REROUTE TO SEATTLE HAD 3 HOUR DELAY. I WAS NOT HAPPY.

On time departure, early arrival since it's a direct flight no connections. Courteous service from the flight attendants. Comfortable seating. Retrieved my luggage in time. Really overall a great experience!

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

My flight was cencaled due with the bad weather on Sunday the crew was poorly mistaken my luggage supposed depart with my flight instead I didn’t have my luggage for almost 3 days the website is poorly respond to my complain until I have someone to do it my connection smooth their not even respon or email me even the have my luggage

8 hours late and the plane smelled like urine, that smell in the morning when your child wet the bed in the night.

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

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.

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?

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

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.

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.

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.

Plane was super cold. No entertainment unless you were with mileage program Getting off the plane was super slow

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

Flight was delayed because of a bird strike. They had another plane available within 45 minutes.

It was a code share with Alaska - would have been great if I actually made it on the plane, claimed I didn’t have a ticket or a seat even thought I was checked in.

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

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

The main problem was delay. The plane was at the gate early and bags were loaded. However, there was no crew for the flight. They were inbound from LGA and had to land and make their way to our gate. It took more than 40 minutes. Then, once the crew arrived and boarded, one of the crew members had to deplane and then a replacement crew member had to be found. It took another 40 minutes or so to get the final crew member. In all, we took off about 2 hours later than our scheduled departure time. Once in the air, the flight was great. Smooth most of the way. The crew was professional and efficient.

i suspect i caught flu on this flight as i could hear someone coughing a few rows back and ended up with flu a few days later. also tiresome to have to watch movies on my device by holding up smartphone screen, would have liked to have in seat display.

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.
