Don't get there earlier than two hours, otherwise you'll be waiting to check your bags in Louisville. It's just a tiny airport.

Arrive early so you don’t feel rushed. Mind your assigned zones. I know people want to get onboard as soon as possible because of overhead compartments, but plan ahead in case you need to gate check your bag. And pack your patience. I know that sounds cliched but it’ll help.

The flight was delayed due to earlier issues at other airports. The crew was excellent & made it a good trip.

Boarding process of asking for volunteers to check bags goes against the system you had before with 2 bags checked free. This process is more of a guilt trip than a caring attitude toward the customer. In addition bag-size scrutiny has increased which also slows down the process of boarding. My wife said she will not fly on your airline again unless there is no other option.

Eveeyrime I fly they are begging for bags due to cabin overhead space. What they should so ia take the bags that are clearly too big to fit wheels first on their side. And those of us who give up the bag should really get their bags first. When boarding, nobody wants stupid jokes about how hot it is on board. Give us some cool air. Im usually sick from the heat by the time we take off.

No wifi, seems to be very common with Southwest currently. Everything else was normal.

Poor customer service, no accommodation for passengers when the flight was delayed over 5 hours.

Friendly crew kept coming by to make sure all was ok, provide additional refreshments, etc.

It was good. Last flight was delayed but I always say that is in God's plan

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

Overall good, just screaming kids in the area the whole flight.

My experience will Southwest was good. I wish there was more entertainment and the boarding process was slow at time but other than that my experience was great definitely will be flying with SouthWest again.

Internet connectivity still seems to be touchy on these flights, making it difficult to rely on it for getting work done.

The ac must have died, it was way to hot on this flight. Boarding g was chaotic. The flight was delayed for boarding. Not a great experience.

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

Awful. There was an unexpected delay of nearly three hours because there were not enough flight attendants. I understand this is likely due to FAA regulations; but in that case, Delta should coordinate with smaller airports such as RDU to have extra flight attendants on the ground and "on call". In addition, this was the second 2-hour+ delay to Boston on this route in one week.

It was strange that the flight attendant was so adamant about having phones turned to airplane mode that he was calling out names from networks shown and waiting until they were all gone. I've never experienced that before, and after already working through an hour+ delay, it felt tone deaf. I take dozens of flights per year and have never experienced anything similar.

The flight was done by SkyWest only WIFI no entertainment center are available on the CRJ

The boarding agent guy in Lexington on 7/23 that boarded the flights to Atlanta is very rude for working in customer service. I know there were delays but he was dismissive rude and arrogant. Most native Kentucky residents are nice and very cordial he needs to eat a big ole piece of humble pie. I watched him be rude to several people and as much as he could of filled up a delayed flight to save you money and he was so rude to people it was ridiculous. Next no water or snacks on short flights is awful 1st you delay a flight then do not even offer water on the flight.. No thanks I like delta better but I travel ever week and to be treated like this might as well fly American at least they offer water and have better rewards.

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.

Flight staff and all was fine. Food always sucks on planes so nothing new.

The flight crew were very helpful. The seats were very close together. There was barely room to sit without touching the person next to you.

I’m an EP on AA every year for more than a decade but this was a very pleasant and surprising experience. Clean and sizable plane for HOU to CHI. 5 row first class. And excellent food in first class the steak option was really good. Your flight attendants even better. Seat 5A

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

My flight was delayed so bad i missed u it so i just said never mind

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

Gluten free snack options and meals that offer both gluten free and dairy free.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

The male air hostess was rude and didn’t provide good customer service. Didn’t even offer me a drink

This trip was a Christmas gift to our family. We were flying from Lexington to Palm Springs. When we were checking in the ticket agent said one bags was over weight by 4 LBS. We were flying first class which has baggage weight of 70 LBS per bag, one bag was 54LBS. We then had to take items from one bag to another. The agent also saw we had a dog with us. Once on the plane we were seated with the dog in the carrier. The United ticket agent came in the plane with two other people, I believe one was TSA and the other some security officer. The United agent said we had not paid for the dog ticket. We had paid for the ticket when we purchased our tickets. She did not give me time to find the email receipt. She then threatened all three of us with either I come with her or she would have all three of physically removed from the plane. I left the plane to pay for another ticket. She had to take my credit back to where we checked in. She acted as if it needed to be done immediately. She said we had 3 minutes. We then sat at the gate for approximately another 45 minutes. This was so embarrassing…to be threatened to be removed from a plane that we paid for all tickets including the dog. The flight attendance on the next leg of our trip were not very attentive to the passengers. On the plus side all the flights were on time. All in all, this was a miserable way to start a holiday vacation. United Airlines showed no compassion towards the whole incident. I feel we were purposely neglected.

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.

The price was the only good thing about this flight. It was scary during takeoff when the plane tilted side to side. It made me feel very nervous as I have never had a take-off that unsmooth. There was no on-flight movie or music options and the only complimentary option was water. Other airlines offer trail mix or a caramel cookie and pop options as complimentary. This flight was a 2.5 hour flight. I understand for shorter flights not having options, but a flight 2 hours or longer should offer more complimentary options and in flight entertainment. Also the seats did not recline and for a longer flight reclining seats are a must for comfort.

A very pleasant flight but it would be greatly improved with wifi to help entertain kids

This is a no frills, get it done, efficient airline. The seat is a lawn chair. You better bring your own entertainment. If you want something other than water you need to pay for it. But they will get you to your destination quickly, on time, and then they will turn the flight around and go right back where they came from. Reliably. Couple times a week tops. If it fits into your schedule, you can’t get there cheaper or faster.

A three hour delay to board and then another hour on the tarmac because they couldn't get a tractor? Ugh.

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

Seats were very uncomfortable and being charged for snacks and water.........

Allegiant actually impressed me, original inbound flight from PBG was so late they gave us a bird inbound from Des Moines and only left 1h late and gained 40 minutes back in the air. Comfortable flight with no frills but no complaints.

Flight was delayed. Crew was good but hot coffee was not available.

Great. Clean. Seats comfortable. Food was free. Had new release movies.

Better perks for corporate employees whom travel often and spend a lot of money with the airlines. Snacks were terrible chips crackers are ideas. Flight and crew were great comfort was fine entertainment not so great so so called status members means nothing

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

Delayed flight. Missed connection, AA put us on a later connecting flight. The connection flight was delayed 4 times and we had to deplane. Didnt get home until 3am, when I was supposed to be home at 8:30p. Zero compensation offered from American. I would not fly them again.

Better snacks but flight and crew were amazing on this flight

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.

We were delayed in Charlotte for almost 2 hours because American Airlines didn't have flight attendants for our flight.
