Boarding, crew and inflight entertainment was great. Could have better food options for a long flight. Paid money and got a seat with extra leg space but was asked to keep my carry on under the seat in front of me which defeats the purpose of buying a extra space seat.

Boarding, crew and inflight entertainment was great. Could have better food options for a long flight. Paid money and got a seat with extra leg space but was asked to keep my carry on under the seat in front of me which defeats the purpose of buying a extra space seat.

Stop asking fir people to check carry on and then bind are free. Then the wait to get your luggage is ridiculous. This particular flight came with a 45 min wait, after waiting in tarmac waiting for a gate inhaling jet exhaust. And how about those landings?! Do the pilots not know the earth is coming up under the descending plane?! This is the only airline I get sick on. Every. Time.

I understand the delays caused by the storm, but that doesn’t mean the systems had to be chaotic. The app showed one thing, the screens showed something else, and the gates kept changing every 10 minutes. It was a nightmare trying to figure out where to go.

Like new plane. Great crew. Comfortable. Clean. On time. Happy employees. Good organization and control of passengers.

Red eye from San Diego. Temperature of the cabin was way too warm and the air duct flowed very little air.

Over a 3 hour flight. The turbulence was almost imperceptible except for 2 short periods which were not bad and over quickly. The attendants claimed "Safety first" and sat looking at their phones for 3 hours with no drink or snack service. This isn't the first time with Southwest. I thinkit may be there new plan of operation. Oh, and it was June 18, Southwest's Birthday which offered free drinks. NOT.

The flight was okay. The pilots did an amazing job and kept us updated on the flight. The flight attendants were okay. They found time to be chatty with each other rather than focus on the guests. One of the attendants was a little less warm when asking about my bag I had on my lap that I was using during latter part of the mid- flight. Mind you, it was not the departure descent. I’m respectful to each and every attendant, it was the tone in her voice reminding me to place my carryon bag on the floor. I hope to have a better experience next time.

Terrible. Even though there’s assigned seating now, they are still the slowest boarding airline of anyone.

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

Okay, not wonderful. Short flight. Wi-fi didn't work properly. Stuck waiting for a gate to open upon arrival for 20 or so minutes.

Bad. Flight was delayed due to maintenance issue with Delta. Seats were small, no service, bag got broken on initial flight. Cramped and hot. Sitting inside with no ac.

Flight attendent didn't let me sit in the empty window seat literally next to me. Doors had closed already so I moved over. She came over, asked for my ticket and made me switch back to the middle. The man on the aisle and I were right on top of each other. Seemed like a real power trip for no reason at all.

Good but since we got in early we had to wait on runway for our gate. That was kind of a bummer but we still got in earlier than planned For entertainment I was watching a movie and getting close to the end of it with 15 min left but it kept jumping automatically to the next movie before finishing.

Delta seems to be getting worse. They are trying to take any comfort away from poorer people to make more money selling it to the rich. I paid for delta comfort and on my flight from Rome to jfk I had a tv that would go on and off automatically and literally no electrical outlets or usbs worked which was advertised in the price of the fare. The infotainment system wasn’t fully working. Luckily the movies worked and the plane was needing a lot of repairs. The jfk to Tampa flight they stuck me next to this really larger guy who was half in my seat and they should have made other accommodations for him because now you’re interfering with the fare class I paid for and act like I shouldn’t care because I didn’t pay for first class. I couldn’t even pull out my tray table because of this guy. The safety video tv screen you couldn’t even see it. It made me a little scared to fly delta anymore, because if these planes are this much in need of servicing, I have to wonder if the plane is going to make it to the destination.

Late flight, screens not working and still had to pay for a drink

They changed my seat assignment from window to middle. I have a physical need to sit by the window because of spinal issues. I unboarded in pain, I also was placed between 2 very large men. I am very disappointed and now dealing with the physical aftermath.

The crew were awesome and ready to help as much as possible. The gate agent in Atlanta was tremendously helpful. The delays were ridiculous. Getting home at 4am when I could have driven home faster was unimpressive. Being delayed for countless hours through the night wasn't a great travel experience.

The staff was fine. The plane was extremely tight, and I paid for the wifi and it did not work at all. I was actually going to ask for a refund.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

The crew was very polite as I have a few handicaps and everything was made pleasant. Check-in was easy as I was brought on board by the wheelchair assistant. One flight attendant did make sure my personal item was carefully stored under the seat in front of me. I was made to feel welcome as a customer as I made my first trip with a few disabilities. Entertainment and wifi worked quite well. The only food service were snacks and drinks. Those were okay. Overall it was a very smooth flight and encouraged me to use Delta again.

1 person checking us as we boarded, left gate on time, 12.30 we are told we were held for 15 mins as other flights were waiting to take off, captain due to rain … they were having a longer gap between take offs , 3pm we took off , they went land route via New Orleans in to Florida landed at 5.45pm offered coffee and a biscuit

It was good flight was smooth, little cold on the plane but other wise good.

It was great. I really love the app. User friendly and very comprehensive when it comes to having information at my fingertips tips related my travel.

The first leg of my trip the Republic Airlines aircraft was late due to a maintenance problem. Then I called United to reroute. Their reroute airline lost my bag but found it and returned it two days later. Hopefully my return trip home is better.

The experience with United Airlines was excellent; however, the experience with Houston Intercontinental Airport (IAH) was horrible. Although our flight departed from Terminal B, we had to go through security in Terminal C and then get on a train for travel to Terminal B. Additionally, there was significant walking required to get to the boarding location.

Flight was delayed 5 hours. Updates kept changing. Sears were extremely cramped. Very little leg room. Flight attendant was rushing through with drinks and hit me in the knee either the cart and didn’t apologize. They gave a 15 dollar voucher in airport which doesn’t buy. Much and it was so late that choices were limited.

Always pretty good as far as I see it. Staff was friendly and process was quick to get on and off.

The flight was delayed because they closed several flight ways because of air shows, fire works, etc.

Lost one piece of luggage even though I checked in 2.5 hours before the flight

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

Terrible. We needed to change return flights due to an incoming hurricane. They would not refund our return flight.

It was poor a four hour delay and no explanation for the delay. What’s a 35 dollars going to do. It also made me miss my car rental,

It was on time. Flight was comfortable. Staff was nice. It was the way a flight should always be.

Allegiant canceled the flight. The flight the next day was full. Allegiant did not provide any compensation besides a refund. Last time on Allegiant.

Great. No choice for n/a. No food or entertainment options

just had water and there was plenty of leg & seat room. But then i don't weight 220#s!!

Not totally their fault- screaming kids that had zero parent intervention.

Check in on the web portal was cumbersome! After several attempts I finally got the boarding pass.

I didn’t like it at all. I miss my second flight because of the delay on Allegiant Air now I m stuck in MCO.

My TSA number was missing from my ticket which shouldn’t have happened since it’s in my file. The on board flight attendant who was a male, did not want to help me put my luggage in the overhead bin and made a very rude comment and was very unpleasant. The good… the woman who fixed my ticket with the TSA number was excellent and I had extra legroom which was perfect.

Flight attendant super rude demanding I remove my carry on baggage from overhead and place under seat. I stated I am an ADA passenger and need the leg room as the seats are very tight. That’s why I boarded early for the extra time to get situated. She said, we need the space. I replied “How can that be as only a few passengers have boarded so far? I am executive platinum status so I understand the rules and you are discriminating against ADA federal law. Please stop”. Her answer… then you should find another flight! Not ok. Addressed with senior flight attendant. So unprofessional and discriminatory.

Good flight, excellent personnel; poor comfort, small seats, big cost.

What an amazing plane! We flew a 787 to Miami. Although the Internet was not functioning, it was a wonderful flight.

It was freezing in the cabin. That's on me to be better prepared in the future.

I have posted the comments in the first flight leg.

Flight had mechanical issues and it was delayed 30 mins - some of us boarded and then had to deplane.

The AA app really sucks ... Every flight & connecting flights were delayed over 30 mins. One connecting flight on American Eagle said it was delayed in its arrival ... when it was actually parked across from the gate for over 1 hr before they pulled it to the gate. Seats in the economy/ main cabin are packed together like sardines ... no leg room.

To start, I’d like to say that every American Airline personnel I interacted with on the ground, especially flight crew, was very friendly and did their best to help me out. Despite this, however, my experience with the airline was an entire mess. The 7:19 PM flight was heavily delayed due to weather, and pushed to 10:30 AM the next morning. Because of this, I had to spend the night inside of the airport. At some point later in the night, I got an email saying that the flight had been canceled. I called the support number, and the representative on the other line told me that the flight was still on and that I didn’t need to rebook. The next morning, no one came to the gate to open the door for the crew until almost 11 AM. By this time the flight crew had been waiting for over an hour, and they had called management to get someone to open the door for them multiple times. Around 11:30, the gate screen had changed to a different flight. I ended up buying a last minute ticket with Southwest airline just to get to Chicago, because the next flight with American wasn’t until 7:19 pm that day. Now, earlier that morning my suitcase had been sent ahead of me to ORD. I went to baggage claim to ask them if I could have my suitcase forwarded to where I was staying. The representative at SDF baggage claim said they could and put the claim in for me. As I was going back through TSA, I got an email that the airline had found my suitcase, but the next step was to send it BACK to SDF. I called the airline support number again, and I made it clear that my suitcase needed to stay in Chicago and to not come back to SDF. The representative told me that they would hold my suitcase at ORD and that it wasn’t going to be forwarded anywhere. Once I got there, I found that they had loaded my suitcase onto a plane to send it back to SDF. Thankfully, I had gotten to the baggage claim counter in time for them to put in a request to bring my suitcase back up. My refund with the airline is processing already, but because of this entire experience and miscommunication at every turn of the way, I will not book with American Airlines in the future.

Cabin was roomy enough to easily slide my carry on under the seat in front of me!

They needed to de-ice the plane. Apparently airlines have a problem keeping their de-icing vehicles in good repair. After we backed away from the gate we sat and didn't move for nearly an hour. Nearly an HOUR with minimal communication from the flight crew. Eventually the sun took care of what American Airlines could not and melted the minimal ice. We finally took of a hour late which, in turn, jacked up our connection in Chicago.
