I can honestly say in the 54 years of my life this was the worst flying experience I have ever had. I was delayed on the tarmac going into Dallas for an hour and 2 hours on the tarmac leaving Dallas. a 4 hour flight turned into a 6 hour flight due to Alaska incompetence. To be honest I will never take another Alaska flight.

I can honestly say in the 54 years of my life this was the worst flying experience I have ever had. I was delayed on the tarmac going into Dallas for an hour and 2 hours on the tarmac leaving Dallas. a 4 hour flight turned into a 6 hour flight due to Alaska incompetence. To be honest I will never take another Alaska flight.

I am mobility challenged and ground crew were accommodating to my needs. One must walk up a ramp to board Alaska planes. Terminal to tarmac to ramp to plane.

The attendances were very thorough and pleasant during the entire trip. The pilots did an excellent job keeping us posted on what to expect. The landing in Portland was executed professionally and perfectly. Boarding was delayed a half hour. But given the times were in, that was no surprise. All in all, my preference is to fly only Alaska Airlines for their reliability and professional service.

All good! No entertainment on this new plane yet but ok for this short flight. Great on time flight! Thanks

These questions are hard to answer. It was not until I checked in that I learned my flight was going to Seattle for a connection and not Portland. I did not get notified, or asked, about this change by Alaska or Kayak. Thankfully I made this flight; but missed the connecting flight and it took me much longer to get home. A service representative for Alaska says this happens frequently with third party companies, like Kayak. Please please figure that out.

I got the last seat on the plane, in the back in the corner against the window, and I paid a competitive price for my ticket several weeks before the flight.

Everything was good. However, the selections of movies and TV shows were boring and unexciting. It was disappointing.

Personal demeanor not good on flight returning to LAX..Great and superb on the way to Portland

Very helpful with my mother who needed a wheelchair at both ends and everything went as expected

The flight was great, the crew was great. Our complaint was that there are no TV screens built into the seats. We used our tablets but drained my battery just watching a movie. The movie and TV selection were okay but not great.

I am still upset that my bag was lost on a recent trip to Rome ; we were inconvenienced and out €150 Euros ; delta has refused to reimburse us

I am very bothered by the events today. I can't believe the flight attendants allowed someone to take my seat and made me move. It was embarrassing. I was in the right. The lady just didn't want move. I can't believe delta would allow this to stand and disrespect my rights as a passenger. The lady complained about her leg and that she couldn't move. Firstly somehow she was able to make it to row 24. Not sure how much her leg could have hurt. Secondly, I'm in plenty of pain myself. I just finished chemotherapy a several weeks ago. My body is constantly sore. Yet deltas flight attendants didn't appropriately protect my rights. In the end they found me a seat on the plane but I want to understand how delta can operate this way. They in essence allowed a bully to get their way.

Good flights. On time. They had a gluten free snack option which was nice

Take this flight once or twice a month. Just don’t cut it from the schedule.

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

Food from the flight from Atlanta to Santiago was very poor..

Flight was delayed due to weather. Crew did a nice job of making us comfortable. No complain complaints.

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

My suitcase was completed destroyed. The top part is broken and unusable now.

We boarded but then sat there waiting on some missed connection people to get on so we sat for about 15 minutes for that. Then we sat again because the passenger manifest was wrong and they had to figure it out before we could leave. That took about another 20 minutes or so. The crew was working hard to figure it out so it’s not their fault. It ended up being a system glitch where someone was upgraded to first class while another person was also in the same seat and it just created a mess that took a little while to figure out. They literally went to every person on the plane asking their names to see who was sitting in the wrong seat. I also hate the entertainment that must be watched on your phone or tablet. Just give us setback screens. It’s so much better. Almost every Delta flight has this now and it is so nice to have them. The crew did a great job. I have no complaints from them. They were very hard working, even with the mishap and a disgruntled passenger.

My priority checked bag was not loaded on the flight. I had to sit in baggage claim in Las Vegas for 2 1/2 hours waiting for the next flight. All baggage staff were very helpful, tracking showed it as scanned for loading. Nobody told me why it wasn't on my flight.

All male crew was just too woke for me. I felt like a sardine. I will never take a window seat or the rearmost seat again. I booked early and did not pay for seat selection and that was a mistake. The security at IAH was atrocious. I was violated and radiated as I was in a hurry to connect to my other flight. I may have lost items under the seat in front of me that I couldn't see nor bend over to look.

It’s been awhile since I have traveled on United. I, along with my family who were on the flight noted how smoothly everything went . Boarding, flight crew and service was excellent.

In general ok, my only issue is that they had no hot items for purchase. I had very little time in my connection due to baggage/customs/TSA, thag I barely even had a chance for a stop at the washroom and buy water, to make it to my gate when they started boarding. I had nothing to eat because the trip started early, so I was ready to purchase, and they had nothing except for dry items like snacks. I had to purchase a mediocre, overpriced cheese and fruit board, instead of at least a pizza or sliders that I was planning on getting. Other than that, it was fine. But that’s typical Air Canada, to not have enough.

How badly can you screw up baggage claim? We were told to go to baggage claim too for our bags from this flight. Another flights bags were there. They finished up. More bags from a different flight arrived. Our bags did not Finally the baggage claim belt stopped working and and are flight was still listed on the arrivals for that baggage claim 2. And then nothing It turns out that they had been delivered not only the United baggage claim but far away on a Delta baggage claim No I never told us. It was only the people looking around who had been on the flight But I’m sure there was plenty of time for the employees to raffle through the bags and steal whatever they wanted

Long wait before take off without an update for 20 minutes. Flight was good otherwise.

Flight delayed over 2 hours . I was flying bussiness never got food cause they ran out of what i wanted

At the beginning of the flight there was some turbulence and the announcement was made that there would be no beverage service. The turbulence only last about 5 minutes then it was smooth sailing. I noticed that first class got their service, but the rest of us did not.

Update departure times in a more timely manner. We are not boarding on time if the plane isn’t arriving until after our scheduled departure time.

Update.us on flight information in a more timely manner. Don’t say we are boarding on time ten minutes before the boarding time when the aircraft isn’t arriving for another forty minutes.

Took off on time and successfully avoided weather that looked to be a problem along the way

I liked everything. Except that my neck was hurting on the seat. I couldn't sleep.

We were delayed Al ost / hours after boarding so that maintenance had to add oil to the engines. Then the oil they grabbed had been left out in the Dallas record cold and was frozen. They had to go back to the hanger and grab some that was not frozen.

They changed my seat from one that I had paid for as an upgrade to a regular seat at the last minute.

Flight was empty so had a whole row to myself. Still had to wait to get the bag due to the negligence at Palm Springs departure.

Everything was on time, we arrived early, everything worked well.

Angela was the best fa ever. She made that 8 hour flight a breeze

Worst airline experience. They were rude and kept changing our seats and/or giving our seats away so our family didn’t get to sit with each other. Almost everyone we dealt with at both airports with this airline was rude. The app kept giving us wrong information making things take longer. Dealing with them before TSA can take close to an hour…longer than I’ve ever had to deal with before. Never using this airline again.

Horrendous. I do not recommend Frontier. The passengers lack manners and decency, and the flight attendants lack professionalism. If I wasn’t in a bind to fly with 48 hours notice for a job interview, I would not have selected a flight with Frontier and I never plan to fly with them in the future.

The reps working at the airport counter were dumber than a second coat of paint.

My costume jewelry was stolen out of my bag. Got to airport and my bag weighed 45 pounds- 5 pounds over cost me $100 Long lines in tier one. No entertainment No WiFi no free drinks or snacks

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.

The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.

It was a short flight so no food or entertainment….

Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.

I’ve never traveled on Frontier before. If you want basic, no frills, friendly service at great prices then give them a fly!
