Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

An entire day of delays. Cost lots of money. Meals and a hotel.

The WiFi and crew on the plane were good, however, the boarding experience was awful. I paid for the Choice Preferred and was boarded in group 5 so all overhead storage was full. They found room for our luggage, but further back making getting off the plane a nightmare. Also, we were in row 6 and the seats were extremely uncomfortable. Both my daughter and I had no leg room and couldn’t wait to get off the plane.

The charges were ridiculous for an hour flight and the turbulence was very scary.

Still need to work out the kinks on the new assigned seating boarding process. Otherwise, a very good flight.

WiFi did not work. Boarding with the new seating assignments took too long. The temperature in the terminal was obnoxious. +/- 80°

The seats are now more narrow. I paid for front row the seats in the front are even more narrow than before.

Only downside was the legroom and seat width, which is always a problem unless I spend more for a premium seat.

My flight from Denver to Minneapolis was excellent. My flight from Minneapolis to Denver was one of the worst I flights I have ever experienced. I had a window seat, the gentleman in the middle seat was morbidly obese and SW should have made him purchase two seats. His elbow dug into my arm most of the way even after I asked to please be careful. I was literally squashed between the him and the window with no wiggle room. The plane was full so it was not possible to ask for a different seat. I realize I should have complained to the flight attendant but I didn't feel anything could be done to rectify the situation. I fly SW often, I will continue to do so as this was my first negative experience.

I was assigned seat 7E, yet my boarding was Group 5, which caused me to have to put my luggage in the back of the plance above `19 or 20 aisle, as passengers who had boarded earlier took the overhead bins in the front. SW needs to monitor bin space and ensure that bin space above the seat are aligned to those sitting near their seats. Also the seating assignments needs to align with group number. Maybe board those last first and so on? Having said the ALL the passengers on the plane were gracious enough to allow me and other passengers in this dilema to retrieve our luggage and helped us along the way. I always love the flight staff, as always their fantastic and I can't rave about them enough!

Flight was delayed by 3-hours and their fix was… complimentary pretzels.

Flight was delayed due to crew being not on time

Flight crew issues delayed my flight by 2 1/2 hours. Causing me to miss my connection.

The staff on board and gate was nice - a welcome change from the usual. We also arrived early, which was a great benefit, given that it takes 30 minutes plus to get bags at SRQ.

The staff was frielndly. The plane was terrible, it was too small and should be decommissioned. There were no back seat screens at all. The only beverages we had a choice from was coffee, tea or water. The only bathroom in the back was behind the flight attendant's jump seat and wasn't working. And I literally felt like I was sitting on top of the guy next to me. It was terribly hot in the plane and we had to sit on the tarmac in Chicago for 1/2 hour due to congestion in Mpls. Wouldn't they have know that before they even boarded us so that we could have sat in comfort in the terminal?

Never got on it. Was re-routed through Detroit and am still in airports 12 hours later waiting for my connecting plane to arrive.

Delta has too many delays now days. It is 1:06 am now. I was supposed to land in Norfolk at 10:30 pm. I got re-booked through Detroit and I’m still in Detroit. I hope to be landed in Norfolk by 3am. I’ve been in airports for 12 hours as of right now. There is a weather delay now but most delays lately have been maintenance.

Very Very late. Subsequent flights left an hour before ours

This is my worse experience with Delta. My colleagues and I were traveling to ICT for work. Usually we connect in Dallas, but this year we decided to book with Delta and connect in Atlanta. We were excited to fly with Delta because we hear great things and Delta is one of my top choices when choosing an airline for travel. On the connecting flights to and from Wichita/Atlanta - it felt hot and uncomfortable on the plane. The plane to ICT was smaller and older and did not have any wi-fi or entertainment. The most terrible experience was at boarding in Atlanta both times traveling to Wichita and then back to Tampa. First on our flight from ATL to ICT - the attendant scanning our boarding pass made us go back to the line when we went up to scan our passes to wait. After a few minutes, she allowed us to come back up to scan but then she asked what boarding zone we were. We told her zone 5, and since we were standing on the wrong side of the small rope partition, she made us go back to stand on the right side. There was another gentleman that came up to board and scan his pass, and she mentioned he was also on the wrong side but she let him go through. Our group had to walk back and forth for no reason, causing an unnecessary delay to board the plane. We have never experienced anything like this, especially when the boarding area was completely empty and everyone already boarded since boarding was earlier than the original boarding time. On our flight from ATL to TPA, the attendants scanning our boarding passes had us scan our passes twice, not explaining to us what was going on. They automatically started tagging our carry on bags and did not explain to us or tell us what was going on and why this was happening. Obviously we knew our bags were being forced to check in but with no reason. There was no announcement or mention and I have never had anyone force me to check in my bag before boarding the plane. We assumed the overhead bins were full but when we boarded the plane, there was a lot of empty bins and a lot of spaces to put our bags. We all were disappointed and frustrated with Delta and will be hesitant to fly Delta again or anytime soon.

Boarding and crew were fantastic, but I paid for a window seat with no window. Seat 11D on a CRJ-900 apparently does not have a window. Lesson learned.

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

Short flight, but no drink/snack service. The flights both going and coming were delayed.

Not being stranded in Chicago for her airport to 11:30 tomorrow morning the 3rd

I was fully checked in the prior night and i was unchecked and then didn’t have a seat when I boarded. Instead of an aisle seat, I was out in the middle seat of the very last row of the plane.

In overall it was a good experience, the only down point was that the entertainment screen was working properly.

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

I understand weather is an issue, but making us chase our plane down at five scheduled gates across three terminals in an airport the size of O'Hare was unfair. They'd have probably been better off to leave gates as TBD until the inbound plane is in final approach instead of running us all over the place. Also, props to the consistently-unprepared ground crew in Richmond for once again leaving my lane parked short of the gate because they couldn't have a crew in place on time with 2 hours notice...

cabin crew was OK, food was OK, the trip from the US to Munich was actually pretty bad comfort wise. Noisy aircraft, lights never dimmed even in Business class (night flight) barely sufficient amenities for the price. I have millions of miles with United but TBH American is gaining ground and Delta has always been marginally better then United although on paper United has more longes and cheaper upgrades.

Essy to get on. The hostess gave very little pop, the plane was late getting in, and we are still waiting for our bags. This sucks. :/

Great flight. On time boarding. Smooth flight and on time arrival at EWR. The flight crew was marvelous and there was a great selection of movies on the entertainment system. Our bags were at the carousel before we got there. Another excellent flight from United.

As previously stated the delay I experienced flying from Wichita to Chicago caused a host of issues. When I finally was able to be booked on the last remaining American flight from Chicago to Cincinnati, the gate changed four times with the last change occurring very near the scheduled boarding time. While I didn't have a problem moving from gate to gate, I did notice and make note of others that had mobility issues and had to move each time for the gate change.

Maintenance took a very long time and then we were in a holding pattern. While a one-off maintenance issue is standard, there were delays on both of my flights for this trip based on maintenance issues with the planes, which delayed both flights over 45 minutes. Thankfully, I didn't have any connections but it wasn't an experience that would make me pick AA if I have other options.

No Snacks or Entertainment. The flight was short, snacks should still be given.

See prior comment about how Kayak mishandled my reservation and delayed my arrival by 6 hours.

Boarding delayed 20 minutes for no reason, no wifi, in flight entertainment, or snacks / waters?

Delayed an hour due to operational issues. Minimal apologies or care for the significant inconvenience caused. Landed at nearly 1am and they still couldn’t find ground staff to get us off the plane promptly.

The aircraft had several problems - from excess fuel to non operational ac. Two hours of delay in Chicago could have been avoided with proper planning and aircraft maintenance.

Crew in Columbia was not prepared for landing. It was a bit of a disaster and getting bags took forever.

We were upgraded to First Class and it was a great flight

We experienced gate changes and a long delay. My seat was dirty when I boarded and I had to use wipes to clean it myself. There was an unpleasant and overpowering cleaning product scent on the plane as well that lingered through the flight.

Both flights were significantly delayed. The flight experience itself was great.

My flight got delayed and eventually canceled, then rescheduled. I and several others had a connection from Boston to Paris and asked several times if we would make it. They assured us we would and then rebooked us mid flight without our consent and closed doors early even though they said they communicated we were a bit delayed. We got stranded in Boston and I opted with being rebooked for a different connection to France since they refused to pay for a Hotel. I've now been in Europe for 5 days and still haven't recieved my bags. There was absolutely no urgency for the fact that I'm in a foreign country with absolutely no change of clothes or any of my medication. Such an overwhelming and frustrating experience.

Automated scanning was slow and somewhat haphazard. Too many people were unfamiliar with the tech and were forced to learn on the fly. The hands off approach of the gate staff made it more uncomfortable. This needs work. Overall the flight and cabin crew were excellent.

The crew for the flight was A+ top notch. They were friendly and professional and made the flight a very relaxing and enjoable.

Rude crew member. She seemed annoyed at me without me saying a single word. Also loudly admonished me for having my bag next to my seat instead of tucked away before landing. Just telling me to put it away and guiding me without giving me a lecture would have been enough.

No included food for a 5 hour flight and the entertainment was only accessible if you had wired headphones (not provided). Otherwise though, great and smooth flying and customer service.

Crew were fantastic and so catering and wonderful! Full score for the entire crew!

Because of weather and mechanical issues our flight was 4 hours late. The only compensation offered to us was a meal voucher to be used only at Boston Airport and only on the day issued. But by the time it was offered to us all the restaurants were closed, so there was no way to use that offer.

Friendly crew, efficient boarding and flight arrived early. Couldn’t ask for a better experience

Terrible. They canceled our early morning flight after midnight on the day of and had no available flights to rebook my family on for the next 72 hours. Yet they still had other flights that were not cancelled from JFK so it couldn’t be based on the weather. It felt like they canceled the flight based on it not being profitable enough for them. I am not interested in traveling with the again. The absolute worse customer service and lack of accountability.
