Flight coming out of Buffalo was delayed, so we had to be rescheduled on another flight from Baltimore to Phoenix which means we had a long layover and got home 3.5 hours late. Shuttle to parking stopped at 10pm, so we had to pay for an Uber to the parking lot and got charged an extra day of parking since it was after midnight. Not the best experience. Long day!

We had a 5 hour delay on the tarmac in Baltimore

Airline travel is always too cramped to really be pleasant, but the cabin crew on this flight did a pretty good job of making up for it by putting on some music during boarding and sprinkling a few funny remarks into the safety briefing and announcements, and just generally being friendly and helpful. It definitely reminded me of why I prefer the in-flight experience on Southwest!

Flight was delayed due to plane not passing inspection And one of the crew had to time out and we had to wait for another one A 3 hour delay

It was one and half hour late... Not sure if any other experience matters.

It was 2 hours 45 minutes late, for no apparently clear reason.

It went well. Plane wasn't full. Will be great when assigned seating is in place

As always it was a pleasure to fly on southwest.

Excellent! There was a delay due to the weather and they did all they could do to keep us comfortable & updated. Thank you!

Couldn't connect to the internet and movies. Needed help.

FA was a bit strange and dodgy not very characteristic of Delta

Third flight in two months where the crew was not there. Comfort seating does not guarantee overhead bin space. Passengers with children are allowed on the plane first - if you are flying to and from Orlando, this means half the plane has boarded before you get on. And somehow all the bin space is taken up. 3 out of 5 flights have had issues with equipment or procedure. Some of these instances caused the flight to be delayed because of a "nuisance" light. One time it was a bag that had been brought on board but did not belong to anyone so we had to return to the gate. Last night we were told the "AC" on the plane doesn't work well and we're 10th for take off- because the crew was late - and that it will get cool when we're in the air. Not sure if this is usual, but I didn't think flight crew could jump seat in first class. Movie and TV selection has not been refreshed for several months- flying one to two round trips each month easily exhausts the list of content.

Great experience nice pilot very soft and easy landing and take off

Flight was delayed before take off and at landing. Baggage took 20 minutes. Flight crew would not serve full soft drink and had to ask multiple times before receiving water.

On time! There were plenty of airport employees who were able to keep us moving in the right direction. The crew on the plane were professional.

I continue to be satisfied with Delta’s excellent service out of LGA. The digit id works well and gets me through security in no time. Whenever possible, I choose Delta.

Was revoked with Jet Blue due to delay from Kenya Air

Great. Seamless. Check in agent at kiosk international was amazing and extremely helpful.

Delta planes have the WORST seat comfort of any plane in history. It's the opposite of ergonomic, in every sense. They also recline minimally, are covered in a vinyl and have no feet rests. Then the disembarking process is chaotic and time consuming (because of the way they load the plane and deal with luggage). Overall, somewhat frustrating but we arrived safely :)

Crew handling the boarding at the gates are quite aggressive with the passengers and must be given training/ refreshing courses to improve customer experience.

Check in was chaotic with only one counter for business class and first class. The luggage conveyor belt at JFK airport was broken so the flight departure was delayed which made the flight stressful as I had a tight connection. Although the captain said they could make up the delay, they didn’t do so.

I had a good time. However, I paid for the wifi and it was in and out the whole flight.

3 hour delay…. Nearly 2 hours sitting on tarmac. Do better, United. Or at least have the sense to not say “we hope you enjoyed your flight with us” upon disembarking.

Everything except the food and entertainment. It was a great experience though

Unfortunately weather delayed our flight waiting for our plane to arrive and due to a little snow time was needed to deice the plane so departure was very delayed and I missed the connecting flight

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

Flight was delayed from 35 minute delayed aircraft arrival to 90 minute delay causing us to miss international connecting flight on SWISS resulting in 16 hour delay to reach detonation causing significant angst, monetary loss and discomfort. SWISS transfer desk and staff was like robots not willing to help at all.

Best part: It’s operated by All Nippon Airways. It’s quite literally comfortable, reliable and respected from boarding to landing each and every time. It’s perfection without extremity in lavishness — it’s how flying should always be!

The staff was very friendly. The seats seemed quite small. Overall the flight was pleasant.

I had very little time to change planes originally in Denver after my flight from Omaha. I had an hour and a half layover in Denver originally and my flight leaving Omaha was delayed an hour because they had to change a tire, which I can understand. When I reached Denver my other flight was late, fortunately, but I still had only 10 minutes to run about a mile through the airport to get to my flight. Again, fortunately, I am a healthy 71-year-old and was able to accomplish this feat. However, the stress was more than necessary to bear.

The flight attendant was very polite and attentive. The food was good.

The flight de-boarded after being informed of a 3 hour delay. The gate agent said we could go to lounge. The flight ended up boarding 20 minutes later and I missed it.

My experience with American Airlines was great. Unfortunately my stroller was not located and has not been given to me and or reached out in return for in regard to information.

Pilots were fantastic - super smooth. First Class flight attendant was very attentive. Main Cabin flight attendant should try to smooth the rough edges of her voice - very shrill / punitive. Hurt my ears just to listen to her. Recognize they have a (tough) job to do - but tone over speakers needs to be less like scolding a 5 year old.

Maybe focus more on delivering a good product vs selling me a damn credit card

Crew were professional and kind. The flight was smooth. But... The internet, which we paid 35 dollars for, did not work for most of the flight. This made providing media for our child an uncomfortable hassle.

Overall fine. Seemed like one of the older model planes? Crew was mostly very kind, though some of the female attendants were a rather abrupt during the food service.

Leave on time. We waited on the plane for hour hours and it was hot and smelly

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.

A much better flight than our previous. The flight attendant took care of us and regularly checked in to see if we needed anything. Brought us drinks prior to the departure and then a couple more times. Totally makes the difference in how you travel when the crew is checking on their passengers. Great job on this leg of our trip.

When I agreed to give up my two seats because of overbooking by the airline, I should have been offered some sort of reward or credit towards a future flight. I was not. It was not until the next day when I mentioned it to a Jet Blue employee that I was advised to call 1-800-JetBlue. So here I am, having done Jet Blue a favor and I had to do the work to find out if I was going to get a credit. Such service

Domestic flights are good. Just stay away from international travel

First the flt was delayed over 2 hrs bc of plane mechanics that should have been handled better! No text or email was sent so only found out at the airport so there we sat for 5 hours! THATS RIDICULOUS! The gate area was filthy! No agents showed up till hr before so no additional info was given-waited online for 15 mins while the gate agent chatted and got together then given last seat in back of plane!! No priority for senior or anything-took attendants over 2hrs to serve drinks and snack-WHY are they not served together? By time snack came needed another drink! Worst service in my life!

Since we started at syr the service, crews, and flights were just excellent

All the TV screens in my rows was non functional . The map shown for an international route was antiqued..

Excellent price. Everything on time. two bad parts. Kayak said I couldn't sign in for the flight online, but I got an email at the same time from Jet Blue and they let me sign in online. Second bad part was that, although I had provided my known traveler number, neither of my boarding passes, for this flight and the previous one, had TSA pre-check showing.

The flight departed more than 1 hour late. Leg room is bigger than most airlines

In-flight staff was very helpful and excellent. However, the flight was delayed by 90 minutes. Also the boarding process should be expedited in case of delayed flights. This will help the passengers trying to make international connections.

terrible. Because I felt very unwell during the flight. How do they leave a woman alone in the middle of 2 men? an obese man who was falling on top of me.

I booked this flight using JetBlue points and I was just so happy. The plane was so clean, I had every need met. Thank you!!
