Delayed for three hours. This seems to be CAL’s MO when flights aren’t filled until they fill it. Business class is nice but not luxe like other airlines. Lots of space and amazing staff.

Boarding the flight was smooth and the flight was not full so i had an extra seat essentially

There was no flight. They canceled the flight with no knowledge to me, and I still haven’t received a refund

The flight was delayed over a hour and that was over 15 hours in advance not good

At check in I had to pay for my seat that I already paid for on purchasing my ticket. The flight was over an hour late and the plane smelt gross.

Flight time. The crew was the rudest, talked down to customers, ignored requests, acted like security guards, used forceful language like must and can't. Everything was on purchase, no entertainment, unless you could use your own phone. Poor customer service.

The flight could'nt be better ,the comfort ,the crew and everything was good.i will definitely fly with this sirline again.

I love my entire experience. What I love most, was the friendliness and helpfulness of the staff at check-in and that of the crew on the flight. Their Customer Service was paramount.

The flight crew was extremely hospitable, though there was a lot of turbulence, they made it a good experience. The only negative was the inflight experience for economy class. There wasn’t any, or at least non that I was aware of.

STEWARDESSES WERE AWESOME! The food could be a bit better. Rice was SOGGY with gravy and the chicken was RUBBERY.

Crew was real good, flight was smooth and came in early.

The CRJ-900 was clean but the overhead air vents were broken in our First Class row, making the cabin very hot until about 30 mins into the flight. The flight attendants were both extremely apologetic and accommodating though so that is why I rated the flight as very good. They checked on us many times and truly showed they cared. The snacks for an hour and a half flight could be better. Would be nice if there was a small plated meal over convenient store snacks. WiFi also was not working. And it would be nice if Delta had adjustable headrests on these planes.

New high end luggage ruined/zippers broken, items missing. All happened on return flight from msp to mso. Do better! Not store bought luggage but high end personalized ogio custom embroidered luggage. Total slap in the face ontop of an extra luggage fee that took me 3 hrs on chat to resolve.

It was as good as it could be. Flying is not a pleasant experience these days.

The plane was old and thus the seats were not good. No cushion left whatsoever, and it all was a bit worn out.

I was in Comfort and we didn’t get any drinks, chips or anything! First Class got full service on the flight and Comfort got nothing. Seat was horrible and uncomfortable

My flight was delayed by 4 hours in 30 minute increments. The gate agents were amazing but the communication was not. We were told that there was a maintenance issue but they didn't know what it was. That didn't inspire confidence. Then they said they found it and it was fixed and the pilot just needed to sign off. Then the pilot needed to talk to the other pilot from the arriving flight and we'd be fine. Then we were waiting for the pilot to call back. Then the maintenance issue wasn't fixed. Then they decided we were getting a new plane (why didn't they decide this earlier??). Fine. But then they announced we were changing gates AND terminals. And we were boarding in 20 minutes. So we all had to run to the new terminal gate. We could have taken off at that time, but we then had to wait for all the people who rebooked on a different flight to book this flight again. That took 30+ minutes because there was only one gate agent. When everyone ditched this flight, I saw it as an opportunity to upgrade to comfort. Delta, the greedy jerks they are, charged me $121. After their delay, their fault, their issues, couldn't even discount an upgrade. They only handed out $12 meal vouchers for the delay. I can't even get a snack from starbucks for that.

The crew was very inconsiderate and rude. My flight was scheduled to depart at 6:00am. I received a call from the crew at 5:40am, asking if I was going to make the flight because I was the only one that hasn't boarded yet and boarding ends at 5:50am. I let them know that I will be at the gate in a few minutes, before the 5:50am cutoff. When I arrived at the gate at 5:45am the gate was closed. Departing early on last minute notice without having all passengers on board is inconsiderate and unprofessional.

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

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

Great staff. Clean plane, but we were delayed for more than an hour due to maintenance issues and had to board another plane.

I was very disappointed with my experience at the United Airlines baggage check. The representative was rude and unhelpful. I was required to remove approximately 1.5 pounds from my two checked bags, even though it was a very small amount over the limit. The interaction was unnecessarily unpleasant, and I expected much better customer service. I hope United will review this incident and provide additional customer service training to its staff.

No extra snacks were available. Meals quality is terrible. Crew was not friendly.

I was exhausted from a long day. The flight was smooth. The first flight during my 3 week travel that took off on time.

Agents at gate were not immediately available to solve problems and once they did they didn’t fix all the fight connections

1 flight cancelled Had to fly out of different city Flight at new departure city was delayed 3 hours causing us to miss connecting flights. By the time we did make it to Prague our luggage did not. Had to wait day and a half for luggage to be delivered. Customer service was not good. Agents did not arrive at gate until 5-10 minutes before boarding

I needed internet for critical matters and it never worked.

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

Horrible I am at almost 2,000,000 miles on United. This was probably the worst flight ever. An hour and a half before takeoff I get a message that they’re changing the plane and I no longer have a seat in Polaris business Supposedly, there was a problem with the plane, but then there was no other plane Finally, they decided to bring a plane from Newark to Washington Dulles Of course the original flight was at 10:45 PM so by the time the plane got there it was 12:30 AM. It had not been cleaned. It had not been catered. They don’t really have people available to do those things when it’s not pre-programmed at 1 o’clock in the morning. The crew had to be changed And the new plane held 28 fewer people than the scheduled plane There is no way you can hate United Airlines enough The people at the gate were actually just fine, but it was management who was completely useless And did they send extra help to the people at the gate? Did they send supervisors? Of course not. Just don’t take United find somebody else or buy a boat

Flight was delayed…once landed at ORD, no gates were available so made us wait for 56 minutes after we landed to let us out of the aircraft!

Entertainment system did not function. USB ports did not function. Wi-Fi did not function. Terrible trifecta…

I cancelled this flight 2 days before departure but I followed your texts and emails and IF you were correct this flight turned into a nightmare.

My flight was delayed twice. The first time because of “plane maintenance” and the second because the previous flight who supposedly “arrived early” took an obnoxiously long time to get off the plane. Total delay was over an hour for no reason. Not to mention your airline repeatedly changed our gate from one end of the terminal to the other. Not very happy about this experience. My previous flights with American haven’t had this many issues.

Very turbulent flight, no drinks, very little service, unorganized boarding, gate changed multiple times

We’ve had a year of delays with American, and this one was another flight to add to that list. It just reduced our vacation by a day! So frustrating. In-flight entertainment (TVs) weren’t working, There was no drinks service due to delivery issues.

The flight was delayed significantly. Communication during the flight was abrupt and caused some panic as we were navigating turbulence. It was also too loud and every announcement felt startling. The flight attendants did not offer any assurances and I felt unsettled most of the flight. The seats, floor and tray table was very dirty. The seat next to me was broken and the passenger sitting there was very uncomfortable. He had a spring in his back and his seat made terrible squeaking noises through the flight.

2 hours delay on my flight causing me to miss my connecting flight. Cause was for maintenance. I understand maintenance is important but maintenance should be done before boarding people!

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

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.

Flight was delayed many times. The crew was friendly but you eleven had to buy headphones to access the movies in the plane. $8 is not a lot for one person but it is when you travel with all your family.

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

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.

Complete and total debacle from start to finish. HUGE mistake picking this airline. NEVER again! Rudest staff in the business.

The food took two hours to be delivered to my seat, when I'm on an overnight flight I want to sleep asap after take off

It's not JetBlues fault but there was a smell on the plane (possibly other travelers) and 3 children behind me that never quit whining. Soccor fans that were very loud. Pilot brought the plane down from high altitude quickly, dropping us hu dress of feet at a time. I've never felt that intense of dropping on other airlines (usually fly Southwest Airlines). But I arrived safely and I'm thankful for that.

Seats were great, the staff was great, and the food was about the best I've had on a plane, and is especially the best of any US-based carrier I've flown. Free Wi-Fi was also great.

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.

Domestic flights are good. Just stay away from international travel

Flight left 2 hours late with no explanation as to the delay
