One major problem that was very unprofessional and uncalled for. Plane landed and we had to wait 20 minutes to get off the plane since they were waiting for someone to come to the gate to drive the jetway. Southwest couldn't have someone available and waiting for the plane to land? Is there only one person in Hobby airport who knows to drive the jetway? Was he at lunch? In the bar? Uncomfortable and uncalled for!

Snacks are always pretzels. Why can't you also offer peanuts ?

On time. Friendly staff. Took to long to pre bord all the specialty groups. Cramped small plane

No delays and arrived to destination 30 min early. Staff was super friendly.

Full cans of soda would be nice. A choice between two snacks would be appreciated.

Tried watching free movie and it kept freezing so I couldn’t finish.

The movies using Southwest WiFi kept pausing and I had to restart multiple times.

First, my flight was a usual flight nothing exceptional or unexpected. Over all it was a normal, good flight! Second, your questionaire is wholly lacking in the proper options to which one can answer a question. Often on short flights, there is no food let alone entertainment so why isn't that reflected in your questionaire? A simple "not applicable" would cover that issue appropriately but no, your form arbitrarily enters an answer based on the initial assessment which normally isn't factual. Until you provide an accurate means of assessing flights, I'll no longer be completing of these unimpressive and misleading assessements. Thank you!

Easy to book and to get check in and get on and off.

Service was great, boarding and exiting went smoothly, and the flight was very pleasant.

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

The international portion was good. Food and beverage options were good. The sustainable wooden eatery was less than desirable. Your Star Alliance partner ANA provided real silverware. I'm 6'3" & 198 lbs and felt cramped in the exit row. How can that be? Flight attendant all had a pleasant disposition which is always good.

Boarded from a very small gate at LAX. Staff at gate had us line up, then waited 25 minutes to board without a word of explanation. Plane arrived on time then waited 20 minutes for a plane to vacate our gate. Majority of bags arrived after 15 minutes but it took an hour for a small number of remaining bags to be off-loaded despite my “priority” bag tag.

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

The flight was delayed, they didn’t even have water for the toilets or for drinks

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

The flight had a delay but I made it to my connection. Flight was smooth overall

My interaction with the flight attendent Eve was horrible. I was seated in 3F and was blown away watching her repeatedly skip me as she took other customer orders for lunch...she took the customer next to me but skipped me, then took everyone's order around me (in front of and behind me) . After she had taken every customer's orders to include those behind me, she came to me and said we are out of everything except one last item. I was mortified, in that, I am a 1k flyer, had pre-ordered AND as an African American could only assume why she repeatedly skipped me...mortified. no words

I was forced to gate check my carry on luggage. Somehow it did not arrive at my destination. I still have yet to receive my bag r days after arrival.

As always, most AA flights that we fly are almost ALWAYS delayed and that too multiple times. Very frustrating

The plane was very creaky and lots of ringing. Plane was dirty and dingy. I couldn't hear the captain's announcements from the flight deck. Not sure if it was the captain or the audio equipment, but good thing there wasn't an emergency where we needed clear instructions. The overhead compartments were clearly full, but the flight crew allowed people to stand in the back with their carry on luggage. Then after everyone boarded, they had to go to the front to gate check their luggage because there was no room for their bags and then they returned to their seats...such a waste of time when clearly the overhead compartments were full when they originally boarded.

Human interaction. Thought there would be more service-even a smile would have been nice.

I booked an aisle seat and was given a middle. At 6'4" 230lbs, it is not ideal to fly in the middle row for myself and passengers.

I had two wonderful flights - very relaxing and got me there early!

Awful. We had an 8 hour mechanical delay- no vouchers and no kind/courtesy/professional representatives in the entire airport. Not only was it a terrible experience for both my 7 year old and myself, I still have not heard back from American about how they’re going to correct it- I’ve sent 2 or 3 emails about our experience- which was just awful. Not to mention according to national traveling laws, we should be reimbursed… but of course they’re not responding.

Help was available but timing was bad in my case

Overall it was good but not great. The aircraft was an old and seats didn’t recline in business class unless you kept playing around with it.

The plane was subbed for another last minute, the gate was changed last minute. Could live with that but we boarded and there was a delay which totaled an hour in the end. There was a technical issue which meant wheels needed to remain out for ten mins after take off. My USB phone charger was broken as was the headphone jack which meant I could t enjoy the IFE and could use my phone after a few hours. Even the map function on the plane failed to work after a few hours.

The flight was delayed and we were told the airplane is on its way to the gate from the hangar. We were told this for 2 hours and the flight was continually delayed in ~30 minute increments. Then we ended up having a new airplane. The issue wasn’t clearly communicated and it left everyone feeling confused about when we would actually be leaving. Whenever they communicated a new boarding time it felt arbitrary and random. The boarding process was a mess and disorganized, which made it last longer than necessary. Landing was rough. Seats were uncomfortable.

Flight is delayed by more than an hour without any reason, the jet blue gates kept changing every 20 mins and there is no proper communication. No ear phones provided in flight, there is a screen with entertainment but what is the use, I have earphones but the console has outdated audio connections, no usb C or bluetooth, they are living 15 years behind

A nightmare. Scheduled flight delayed 2 hours then cancelled because pilot timed out . Unable to find another pilot. Really?! Weather certainly a factor, but JetBlue seemed totally unprepared for the chaos that ensued when flight routes were cancelled. More cancelled flights, finally many of us who had been bumped from other flights were allowed to board a Boston bound plane around 3:00am, delay after delay, sat on tarmac for another half hour while pilot dealt with weight distribution issues (?), arrived in Boston 4:30. Crew were wonderful- same attendants all day and night and they were exhausted. Fortunately for me and my son that Boston was our final destination, not so lucky for many who missed connecting flights.

The flight was delayed 14 hours and communication was very poor. No one seemed to know what was happening and the gate agent was trying to help people for several flights. She was by herself trying to help 100s of people.

JetBlue worker, Blythe, was so amazing at the DCA counter. If it wasn’t for her, I’m not sure we would’ve made it through. Please thank her!

On time, friendly attendants, quick wheelchair assistance and help checking in bags. Also appreciated change in seats, more forward to make it easier for my 97 year old mother to board and exit the plane. Thank you, JetBlue!

Flight was on time and smooth. Customer service was decent

They forced me to check my hand luggage at the gate.

Still hasn’t left. Why are you asking how it was?

Going through JFK’s security is a mess. The TSA security said no shoes on the bins. So, we place our shoes in the belt and they came out all over the belt. Boarding was delayed and Flight as well.

I loved the flight and the crew. It was comfortable and smooth.

Terrible. Delayed my family flight for several hours affecting family plans

Flight was delayed and then my second leg was completely canceled. Had to get a refund

When I wanted to check in 3 hours prior to boarding time, the employees mentioned “a little over an hour delay” so I waited for an hour then I went to go look for food in the terminal and most people from that flight were in the same area looking for food. Finally I decided after food to check to see if it’s anytime closer and now it’s 2 mins until boarding closes?! What are you kidding me? I didn’t receive anything via sms about boarding now nor via email or on the intercom. I luckily made it through, barely, and then there’s no room for my carry on mind you I’m in the very first row so I had to place my purse in one further row back and my carry on sections down. Not sure who pays for better seats to get your stuff placed all over the plane but that was the worst experience I’ve ever had flying with anyone.

My flight was canceled I was promised a reginf still not received.

The worst service , the agents from the counter are really bad . Poor customer service . They didnt help me to get in the flight . I was on line when they close the flight without telling and I couldn’t board the plane . I will like to get my money back ey back because it was their fault. Really bad management , bad manners, bad additud

Very delayed with little to no communication from the captain or flight crew. All announcements made were not audibly understood by passengers. Very poor communication. After arrival it took approximately 20 minutes to get a jet bridge to the plane.

I fly Frontier often and generally don't have any issues. For some reason, the Denver to Houston's George Bush Intercontinental (IAH) flight always needs to wait on the tarmac in Houston because a gate is not available after landing. I've been stuck for as little as 15 minutes and as much as a little over an hour. I know only fly the Frontier Denver to IAH route when there is not an available flight to Houston Hobby (HOU).

Terrible Y lost my connection to Mexico, nobody of your company help me And y pay a lot of money for my baggage Until now I continue in the Houston airport I vneed you return my money

Everything was good, 20/30 minutes late waiting on a crew member. It’s hard to keep employees. Or serious employees I know. I remember one flight from Houston of Frontiers was almost 18 hours late. And another 4 hours late very poor. But I would rather be late and safe than the on the news. Thank you.

Good - Leg spar, cleanliness, and on time performance. Bad - No snacks and entertainment.
