Flight was scheduled to leave at 6a and delayed for 5 hours due to “mechanical” issues. Everyone else on the flight received an email voucher for $24 of food for the delay, except for our group. Also the carry on luggage bins were full and the crew requested that everyone to pass their carry ons back up to the front while everyone was still standing. They gave no other direction and kept rushing the process. After all bags were sent up, they then asked for seat #s to go with each bag… They should have probably had everyone get to their sits and then pass the bags up in a controlled process.

From Las Vegas to Boise all went well. However, our flight was delayed in Boise and I missed my connecting flight from Seattle to Pasco. Moreover, the last flight to Pasco was full and I was booked on the 11:30 flight Sunday and given a hotel accommodation. However, I was scheduled to deliver the Sunday morning service at my church and needed to arrive no later than 10:00. Therefore, I booked a Delta flight scheduled to arrive in Pasco at 23:09. My piece of luggage checked in Las Vegas arrived in Pasco earlier today. I waited at the airport for over an hour last night to speak with an Alaska agent to no avail. I went back after church this morning in search of my piece of luggage and it could not be located. After waiting for 40 minutes to speak to the agent authorized to take my claim, he announced that he was closing the counter to assist on the flight line but not before providing me with a telephone number that would help me with filing my claim. Before I was able to make the call (due to other factors) I received a call from Alaska agent informing me that my luggage had just arrived and I am now waiting for it to be delivered. I deliberately took the more complicated route home to ensure that I would be home in plenty of time to prepare for myself for the Sunday service and accommodate my relatives’ needs. I believe the airport is undermanned given the number of flights coming in and going out. It was fiasco last night with three flights waiting for luggage and another flight landing within minutes. Today’s problems stemmed from a lack of cross training and a serious amount of cargo/baggage going out and too few people scheduled to cover.

The seats were not very comfortable and there were no TV screens. Boarding was pretty fast because there were so few people on such a small plane and I appreciated that they still gave us our snack and drinks, however I really wish they would come up with a good gluten-free snack.

Flight crew and flight were good. But it departed two hours late.

Food was bad. Just a drink for a 5 hour flight

Leg and arm room are horrible. I am not a big person and found it tight.

Pretzels are always a disappointment. Cheezits, Sun Chips, trail mix, anything else would be nice.

Late. Too long a flight for a 737. 0.5 oz of pretzels for a 5+ hour flight at dinner time. One step above Ryan Air/ several below Delta.

The plane boarded late and arrived late which wasn't really ideal.

My seat. The reprentative on the phone was bad. The passengers screamed at each other and no one stopped them. The directions boarding the plane were unclear. There was a medical incident and the ICU nurse present said the women was having a cardic incident. Cooler heads determined it was a UTI. I had a allergy attack and a guy got a mask from the flight attendent and told me to wear it. He "had kidney failure". Why didnt they tell him to wear the mask, why was he even on the plane? It was embarrassing, he said hurtful things. By the way, I have a degree in Medical Micrbiology from Northwestern Medical school. MT(ASCP). Look it up. I Know the difference between allergies and an infection. But we had to listen to the unstable screaming man.

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.

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

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.

it was a very short flight so my expectations were low.

As great a red-eye flight as red-eye flights can be.

Very old flight - time to retire it for newer airplanes

2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

Very disappointing given gate agent behavior. Filed a formal complaint with United.

We arrived 25 minutes early only to be told our gate was occupied and so we sat for close to 30 minutes to pull into a gate. That’s not an early arrival!

Experience was great. The best part is the free Wi-Fi connection which helps me to work on the flight

The gate agent had a really bad attitude and refused to help me get on the standby list. She just handed me a card and said I needed to call a number. I asked her to help with the AA app on my phone and she just shrugged and said she didnt know. After a few phone calls, I eventually just went to a different gate agent on the other side of the terminal and got the help I needed.

The TSA check in took 1.5 hours to get through in Austin and I missed my flights back to DC

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.

Overall, my last three trips on American Airlines have all been either delayed or "rescheduled" due to mechanical issues. At least on delay caused me to miss two possible connecting flights each later than the first. My last option for my last connection required the assistance of the onsite service desk (O'Hare Airport). The wait time for the service desk was such that it jeopardized getting booked on the last connecting flight available for the night. Suffice it to say, my latest experiences with American Airlines have caused me extensive loss of productive business and personal time and can therefore be classified as significantly less than satisfactory.

There was free WiFi (definitely a plus), but the flight was delayed 45 minutes waiting on a catering truck that never arrived. The pilot said there would be food vouchers given out at the end of the gangway to make up for the inconvenience, but there was no one offering those. Delay made me late for work!

Waiting for gate in RDU for more than 20mins is crazy.

Flight was on time and there was an empty seat next to me. That makes for a good flight!

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.
