The crew was excellent but the entertainment did not work. The 3mm jack for the headphones was faulty and no sound was available for entertainment.

The crew was excellent but the entertainment did not work. The 3mm jack for the headphones was faulty and no sound was available for entertainment.

Very aggressive at the boarding area of only allowing one person passed a line/ sign

We were delayed so pilots can rest and had no WiFi the whole trip. First class seats are small compared to other planes

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

My tray was broken so i had no place to work or eat except my lap. Flight attendant said I would get an email with some credit or miles, it was a complete waste of time as I could only function at about 20% of normal. I have not received anything yet.

Originally, I was booked in economy. I paid several hundred additional dollars to upgrade to first class. Then I paid several more hundred dollars to change my flight to a slightly earlier flight. I asked if the changed flight would also seat me in first class, and I was told that it would. When I boarded the plane, however, I was seated in economy. So, I paid $500-600 more than I paid for my original ticket for an upgrade and a changed flight - received the changed flight (which was nice), but did not receive the upgrade. So, I was not completely satisfied.

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

This was the second flight this week with flight attendant Marcus I’m not sure if his last name is Lane or Lang but this guy is awesome. He funny, attentive and his service is 5 stars. Marcus makes business travel more enjoyable !

My seat was moved closer to the front of the cabin since I had requested wheelchair assistance to the gate.

Carly the flight attendant was extremely helpful and very accommodating to passengers on the flight from what I noticed. Couldn't be more satisfied with the service and assistance from Delta's flight attendant, Thanks again Carly!!

The flight to Houston the agents were not very helpful

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Everything went well except the turbulence what no one have a control of but pilot and crew handled very good!

In Liberia airport 5 min before our departure the airport was closed for takeoff for 30 min. Upon arrival to IAH we didn’t have any available gate and waited taxing another 40 min. As a result we arrived for 1+ h later. The walkway to the passport control in IAH is about 1-2 ml long. After the passport control you have to pass the security check again. Only 3 out of 16 checkpoints were open and the line was enormously long. As a result, even though we supposed to have 2.5 hrs gap in between the flights we missed our transfer. United rebooked us for the next available flight early morning and provided free hotel and meal vouchers through.

The staff was nice, however boarding taking 2 hours. That’s insane. Overall very bad experience, a lot of turbulence and when landed in Chicago was horrible. I don’t think I’ll flight with UA again.

I still prefer Delta, but Delta doesn’t fly to State College PA.

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

Nothing bad to say about the actual crew or airline. It was nice to have a complimentary FULL can of soda, as well as a snack. Blankets and earbuds were also provided at no cost for this red eye flight. I especially appreciated the free WiFi and movie selection with the Bluetooth option. It helped the flight pass more quickly. No matter who you fly, boarding and disembarking are always SUCH a pain. As I mentioned, this is on the passengers and not the crew!!

Flight attendants rude and impolite… flight delayed by almost 5 hours.

Ok so apparently the new policy on United Airlines is that customers in the main cabin should NEVER be served more than once and besides picking up trash there should NEVER be another interaction with the customer for any reason.

I propose enhancing the legroom across the entire cabin seating area and expanding the snack selection. The airline companies should prioritize customer needs over the extravagant and unjustified salaries of upper management.

KUDOS TO ALL THE CREW PROVIDING ASSISTANCE WITH PASSENGERS ON A WHEELCHAIR. ON BOTH FLIGHTS THEY HUSTLED TO TAKE MY RELATIVE TO CONNECTION ON TIME. THEY DESERVE A LOT OF CREDIT!

The comfortability was very good. Except, when entering the craft the the first steward never greeted us upon entering the airplane. He spoke too fast where his words were all jumbled and difficult to understand.

Purchased through 3rd party vendor which made everything difficult. Unable to check in online. Unable to get flight updates easily, tsa precheck information didn’t carry through, longer time to check in in person. Entertainment looked good but had to purchase conventional headphones to view.

Boarding was done extremely poorly, with huge crowds gate loiterers blocking people from boarding, multiple lines of people trying to merge into one line. One of the male flight attendants who was doing drink service was not happy about having to let a passenger back to their seat and was unnecessarily sassy about it. I thought he was pretty entitled and not a great ambassador for JetBlue

Even though the weather made a lot of flights become cancelled Jet Blue made the flight that was supposed to leave at 9 pm and we left at 12:15 am and I was so grateful- Thanks to the Senior Jet Blue Staff who made those decisions

Arrived as recommended at 8:15 a.m. for an 1115 flight, that kept getting delayed delayed and delayed and then finally canceled. Instructed for the split flight to go to Fort Lauderdale, and then find our way from there back to New York. I don't think I will ever trust flying with JetBlue again. This was my second horrific experience and I am really angry.

We were made to wait in the airport for six hours for a flight that was ultimately canceled.

The inflight system with their wifi is a hot mess and doesn't work. Separately they do, but when you try to do theoretically simple things like pair a device for control it all falls apart

Great crew. Smooth flight that was on time. Boarding is a disaster as usual. Bought more room seat and was Grouo A. The flight was packed by the time I got on. TVs did not work as usual

My flight depature was changed. Then it was delayed, and then cancelled after I reached the gate.I paid $231 for a hotel room that I didn't get to use because I arrived 24 hours later than I was suppossed to. My wife had to pick me up from the airport and I had to pay for an another ride back to the airport the next day. They did get me faster/ priority through TSA. The 2nd flight was okay

The bathrooms for most part were staying clean. The food on the flight was terrible used to be better and the crew was not always friendly, barking orders for no reason. On the short flight, the food/snack was not even offered, and if you want to have a water, you have to come and ask.

It was significantly delayed. Also the admirals club in Philadelphia airport near Gate B is absolutely filthy. Good was on the floor. Flies on the cheese. And the men’s restroom had pools of urine on the floor. I am not using that lounge again.

It was good overall. On my transition from Philadelphia to Boston,the gate information wasn't correct. When I went to check the gate information; I found out that my flight was boarding clear across the airport at another gate. Fortunately I rushed over there and made it on time while they were in the middle of boarding.

For the first time in all my travels I found the arm rests very inadequate and painful. The arm rest between me and the passenger to my left was thin and didn’t support either of us. On the right side, (window side) the armrest was thin and short causing me pain mid-arm.

I've flown American several times this summer and I have yet to get a flight that leaves on time. However, a delay is better than a cancel. So far I have had four canceled flights and two delayed flights

The flight was delayed and was not forthright on the time that it was likely to depart where Flight Radar 24 was reflecting a later time that ended up being accurate for the takeoff. The plane was filthy with food smashed into the carpet and crumbs were piled under the seat where I was to put my backpack. It looked like a full sized Lotus Biscoff cookie was pulverized under the seats in my section. The seats were so uncomfortable especially when the person in front reclined his seat completely to where it was smashed against my knees and I am only 5'2". The fruit and cheese box for $13 was lackluster with no flavor and not satiating at all. The plus side is that I did get one full can of ginger ale. The flight attendants looked miserable and tired, probably due to the last minute need for a new flight attendant to fill in since the original one assigned could not continue on to service this flight. Improve the flight experience for customers and maybe the irritability and stress of flying in today's environment will not negatively impact the joy and stress of the employees/flight crew. This is why I prefer to fly non-US carriers whenever given the chance.

DELAYED AGAIN and AGAIN and AGAIN - not only that, you delay in 20 minute increments for hours and hours instead of having an accurate delay understanding.

Communication not good, too many changes. Three flights were cancelled due to weather and the options were not acceptable. I had to cancel my Canada portion of the trip.

On time and stellar premium class service. Not liking non LCD display in seat backs - miss the convenience of not using your own device.
