In GEG I arrived at 0930 for a 1600 flight. Alaska had a rule that you could not check your bags until 4 hours before flight time. I was forced to sit in a chilly lobby for hours. I had access to a bathroom, but could not go into terminal for food and drink. Boarding and flight OK

PAID First class. No use of lounge in Phoenix (should have a code share). Bags checked and not marked first class, asked attendant who stated on mark gold members. Last bag out of carousel. When you pay extra, expect that...wifi was rebooted and not functioning to allow internet access. Food and cree were very good.

I made a mistake. Read what I wrote in the flight from Dulles to SEA. The negative experience was from SEA to BOI. Total garbage. Wont do it again.

For longer trips, snacks are puny, boring and don’t have ANY nutritional value.

Flight was smooth, but the overhead bins were not deep enough to stow bags vertically and we ran out of room - even with 8 passengers voluntarily gate-checking their bags.

Amazing. They work with my disabilities with such kindness, attention, wnd diligence. They make it easy for those of us who need a little more extra care.

They always change the schedule. My original flight got canceled. They put me up in the air flight. I had to stay seven hours in Seattle. That is bad.

Flight delayed due to engine issue. For 3+ hours still not on flight

One of crew 25 minutes late. Cant underdtand anything on sound system from pilot

No TSA pre check on boarding passes. Was told known traveler numbers are only kept with Alaska Airlines mileage plan members. Did not notice until reached the head of line, and then was sent back through the line to general boarding which took almost an hour. Learned two things: check our boarding passes, which we haven’t had to do with our other airlines, and don’t fly Alaska! You used to be much better!

Southwest is typically delayed, and it gets wearisome. It is no longer a discount airline and you get way less than you pay for when it comes to comfort and Ce.

We sat on the plane on the tarmac for 4 hours.

I'm not a fan of Southwest's model. I don't like the herding style of boarding.

Flight crew and cabin crew were great. I had to rearrange flights because my original flight was 3hrs delayed for weather, the rub is the flight I moved to boarded on time then we sat at the gate for 2 hours because scheduling stole our first officer for another flight, TWICE. Then our actual FO was an hour delayed. To make it worse my original flight went from a 3 hour delay to departing 15min EARLY. Just poor scheduling operations all around.

Bring back peanuts Take our drink orders when were all seated, especially after you switch to assigned seating.

Staff was far less than helpful at all times. Departure and arrival times mean nothing to Southwest. Extremely disappointed, will never fly with them again, and I’ll be sure to share my experience with all.

It is southwest seat was ok. Not the most comfortable seat

I’ve always loved Southwest. No issues at all. I was flying standby and the gate agent was extremely friendly and helpful. Boarding was smooth and I was able to get a window seat in the emergency exit row. Crew was fantastic! They were very professional and accommodating. We had to divert from our destination due to weather but the flight crew kept everyone at ease and informed us of all pertinent information. Excellent flight

The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

Plz don't take away free bags and free seating

Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

My flight was 6 pm 6/6. Every hour they delayed it again - air condition issues then no pilot then the crew had worked too many hours and cancelled the flight at 11 pm. Sent customers to NJ a 45 minutes uber ride to a hotel. Had to be back by 5 am for a 7 am flight and again no pilot etc with another three hours of delays.

The entertainment and wifi mostly didn't work on this flight.

Terrible entertainment system - kept freezing and audio kept cutting out. Snacks were mediocre at best for a 5 hour flight.

The check in and bag drop off for Sky Priority members is slow. The Clear security was also slow - a TSA issue.

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.

Flight was canceled with no voucher of any kind and next available flight was two days later.

Boarding was chaotic. Microphone not working properly and second agent was distracted from task with baggage and late arrivals.

I DID NOT GO TO HAWAII ON HAWAIIAN AIRLINES. YOU DID NOT INFORM ME THAT BY CHOOSING BASIC ECONOMY, I MIGHT BE REQUIRED TO FLY STANDBY. I AM ELDERLY AS WAS MY COMPANION WHO IS ALSO SEVERELY DISABLED AND THERE WOULD BE NO WAY WE COULD TRAVEL ON STANDBY. THEY TOLD ME THAT ALL OF THE BASIC ECONOMY SEATS HAD BEEN SELECTED BY OTHER PASSENGERS AND WE HAD TO PAY AN ADDITIONAL $942 TO GET A SECURED SEAT ON THE PLAN AND, IN SPITE OF THE ADDITIONAL COST, WE WERE NOT ALLOW US TO AMEND OUR TRAVEL PLANS TO EXTEND OUR VACATION. ULTIMATELY, THE FLIGHT WAS DELAYED. WE WERE OFFERED A REFUND IF WE CANCELED OUR TRIP ALTOGETHER WHICH WE DID. IT IS YOUR DUTY TO INFORM YOUR CUSTOMERS OF THE POTENTIAL PROBLEMS THEY MAY FACE, AND YOU DID NOT DO SO. I WILL NOT UTILIZE YOUR SERVICES EVER AGAIN.

It was very pleasant. The staff and crew are very polite.

On time. Alaska upgraded seat comfort with memory foam seat covers with head rests

the people at the counter, NEED TO BE MORE HELPFUL. we had three suitcases to check in and we were not trying to be an INCONVENIENCE TO YOUR clerks. but she was not helpful and made our trip back home memorable but not IN A GOOD WAY. Sadly to say, you guys need to teach to be and to go above and beyond to help THE CUSTOMER BY ANY MEANS POSSIBLE. they need to leave aside whatever they are going thru in their lives, THEIR WORK DEMANDS THAT OF THEM, IF NOT THEY ARE NOT IN THE JOB THEY SUPPOSED TO.

Because the airport is under construction and because Hawaiian air just changed terminals we missed boarding out flight by 5 minutes. That cost me a night in an airport hotel and several hours of rebooking to make it to my destination. Costumers need to know that airport construction is a problem and they need to add an hour to deal with the air train delays from Federal Circle.

Half of my family members didn’t make it because they involuntary bumped off . And their seats where given away

Hawaiian Airlines staff is always professional & quick & easy check in & boarding process

Customer service by Susan of Alaskan Air was outstanding. We missed our flight out of JFK. She got us rebooked the following day. Way to go Susan.

Overall, a good experience. The food, however, was subpar. The breakfast was a joke.

First world problems, but still… We were seated in first class and asked for a cocktail on a very short, 50 minute flight. After our drink order was taken, a half hour went by, and we noticed that every other person in the small plane had been served except for us. We got up to ask about it, the drinks finally came, then were taken away three minutes later since the flight was so short. Really strange situation, on the other hand, we were in Utah.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Wonderful crew and early arrival to our destination. It was so nice to have free wifi access and movies too. Thank you!

Bigger seats. Board back to front! Disembark front to back!

Plane was pretty clean, staff was friendly and helpful, flight left about on time arrived early. Took a long time to board and get off the plane - carry on items didn't have enough room so people had to move all around to find places.

Service in first class no longer exists on American Airlines .

My seat was very worn. Otherwise I had an excellent flight

Boarding can be more efficiently done by having the back row passengers board first. This way, the other people do the have to wait for front row passengers to load their luggage in the overhead cabins. Food is simply pathetic for the price I paid. Cleanliness is simply poor; my seat was full of crumps.

Always a great flight on AA. PHX to DFW and vise versa is always going to be a pretty full flight but the crew handles it phenomenally.
