Uneventful, which is perfection in airline travel. Everything happened as it should and when it should. Flight was short so no food. I could have used the App to watch something but took a nap.

Uneventful, which is perfection in airline travel. Everything happened as it should and when it should. Flight was short so no food. I could have used the App to watch something but took a nap.

Stop with the fake cheerfulness and the too often expressed sentiment that all you care about is our safety. Bull…. You use that as an excuse to keep us cowering in our seats. How about you go back to the old standby of telling the truth… like why you overbook, why you are delayed, why we don’t get vouchers for your screwups.

Healthier snack options in first class. Offer fruits, proteins, etc

Last minute change in gate to satellite N a bit of a hassle since I needed a wheelchair . Someone did come and get me to the gate but it was close. Then plane late. It’s hard on older passengers and families to have to trek from one gate to another.

Still seems like Alaska Airlines is not doing a very good job of anticipating the number of carry on’s going in the overhead bins. I was asked to check mine not to find out there was actually(surprisingly)enough room for my small luggage in the overhead bins. In the past, I’ve seen PLENTY of items in the overhead bins that should be underneath peoples seats.

It seems like most of the time theres no room for my allowed carry on bag. People are putting their things in the overhead compartment that belong under the seat in front of them. Getting tired of that!

The seats are too small/crowded. It is frustrating to be forced to sit with someone who is overweight as they crown the other seat. Nothing against the person…just the airline companies who continue(over decades!)to reduce seat sizes. Americans are fat. Those of us who are not are tired of being compromised by the airline companies who don’t faces that fact and make adjustments. Maybe have “overweight seats”? Maybe give us a discount for being forced into an uncomfortable flight due to others overweightness? Please, make adjustments…be accountable. Thanks!

The crew was great and everything went smoothly coming and going.

No outlets, plugs, way to charge the phone or service and no food on one leg o the trip, but other than that, great. Loved WIFI, the flight, the crew, the pilots, the schedule, etc. Great job. My new favorite airline!

Wonderful as always! Pleasant staff, smooth ride, and timely departure.

They did not fix the wifi that they knew was an issue on an earlier flight. The flight was filled with business people that were clearly frustrated not being able to work. That can’t happen on a 3 1/2 hour flight. Would rather have been delayed a bit.

The WiFi did not work three hours of productivity lost. 15 people from the firm were on the flight. Loss of revenue

Very rude stewardess; there was a senior citizen woman next to me who asked the stewardess for help getting her purse out of the overhead bin, and it was as though she asked the stewardess for $1M . . . . I was shocked how rude that stewardess was. The stewardess also refused to get the senior citizen woman a drink about half way thru the flight, telling her that we were almost landing . . . . that stewardess made my flight (and in particular the flight of the senior citizen next to me) very uncomfortable

Overall good experience...exception: very cold temp in teh cabin.

I liked how it boarded fast. I do not like how the seats are just too narrow, and I’m not a big person.

Stop asking fir people to check carry on and then bind are free. Then the wait to get your luggage is ridiculous. This particular flight came with a 45 min wait, after waiting in tarmac waiting for a gate inhaling jet exhaust. And how about those landings?! Do the pilots not know the earth is coming up under the descending plane?! This is the only airline I get sick on. Every. Time.

I understand the delays caused by the storm, but that doesn’t mean the systems had to be chaotic. The app showed one thing, the screens showed something else, and the gates kept changing every 10 minutes. It was a nightmare trying to figure out where to go.

Multiple delays due to weather in Chicago, but the crew did their best to get flights rescheduled and on to their destination. I felt like the crews handled a frustrating situation very well, kudos to them! I was very glad to not have a cancelled flight.

Southwest’s point to point system caused a 2 hour delay due to the crew being late from their inbound flight. Also, the WiFi and entertainment didn’t work on the plane.

One, we were met with more than six hours of delays with no information flowing from the airline to the passenger. I had to continually refresh for updates to departure time - which changed multiple times throughout the day. Updates were never pushed to me nor was an explanation provided for the delay until this morning. Two, while they claim that "due to the short flight" no beverage service would be provided. Our flight was mostly empty. I'd think given the massive inconvenience, SW could have shared a Diet Coke and some peanuts. And BTW, SW used to always make these available on this flight back in the day. Let's be honest, this is cost savings at the customer's expense.

The cabin and bathroom experience was poor as the cabin and bathroom were dirty and showed signs of an older plane that had not been updated for Customer’s, comfort and health. There was gum on my seat when I arrived and dirt spots around the fan and light controls. The flight was almost entirely full, so there was no way I could be moved from my seat. Th bathroom had the peeling paint.

Wifi worked inconsistently; outlet to charge computer did not work.

Gate agent in LAS named Juliett should win an award for excellent customer service.

Gate agent and flight attendants were efficient, but more stern than warm.

The only issue is that the plane was HOT. This was not the case on my first flight so not sure why, but thankfully I had a portable fan with me. Everything else was great!

13 hour delay stuck in Detroit and missed a day of meetings. It was terrible

My flight was so delayed I would’ve missed my connection and had to cancel my trip

Seemingly unnecessary delays were compounded by a lack of communication from the flight crew which turned a four hour delay into an overly stressful experience.

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

Having to up charge for a seat assignment is not good. Delta can do better

Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!

Old plane, no amenities. Very abrupt landing. Unnecessarily long taxi time.

The flight was for my mom in wheelchair the staff in Newark wer not friendly took a long time to even get a wheelchair she almost missed her flight because they finally got a chair few minutes before boarding they had to rush her to the gate. They took her carryon and checked it as a bag told her don’t worry free of charge but they charge the credit card anyway. She also told me the seats are not comfortable at all as if they were broken she could feel the bars in the seat SFO staff was much better overall she had the worst experience

Wifi is very frustrating - could not connect and therefore unable to work on the trip

Entertainment was great. Seats were good. They did not have my pre-ordered hot food product available but did comp me something cold in place of the item.

Good flight, even though there was a delay, still got back on time

Santa Barbara is a super small and easy airport. Breezed through rental car return, breezed through Security, ordered a coffee and muffin and to my gate in less than 30 minutes. Maybe because it was a small airport we got the oldest plane. Hardly any overhead space and absolutely zero internet. Its NFL Sunday man! That hurt.

We were delay because so many bags needed to be gate checked and it was disappointing not to have outlets in the seats for such a long flight.

There were no vegan options for first class. Even though we were promised the satellite internet for free, we received NO wifi at all. Even though we were promised a 20-min early arrival, we ended up over 30 mins late.

No water or beverage was provided. I had to ask for water. The sole flight attendant had more interest in selling the credit card. In addition when we got to Dulles the plane and gate were misaligned and it took at least 15 minutes to get off the plane.

Internet is much improved, which is very important to me a s a business traveler. The off boarding of the plane was fantastic. Very quick and very orderly. We had to check our carry-ons before we got on the plane and they were retrieved and available to us very quickly. We left on time and arrived early. All very good things

My seat was defective. The suppor was broken under the cushion so I road on metal for 4 hours

There was an issue with engine, flight delayed for several hours, lost a connection

I always looks forward to the Biscoff cookies and they weren’t offered….

I was truly shocked at how poor this flight went. The crew was not friendly during the checking process. The asked for people to gate check and were rude about it. They didn't handle my luggage with care. When I got to my seat I noticed a large section of the ceiling vent area was, no joke, TAPED TOGETHER WITH CLEAR PACKING TAPE! To add insult to injury, the back rest button was disabled on my seat and all the seats I could see. The wifi, never connected for me, despite troubleshooting it for a while. I did everything from restarting my wifi/phone to forgetting the network and restarting the app. But that didn't stop the mandatory 2 ads from playing every single time. Even the bags took over 45 mins to arrive at the carousel. Everything about this flight was a flop and I am beginning to notice that some of these events are becoming a trend. Perhaps it's time I switch loyalty programs.

Had to find alternative flights because of AA lateness and bad planning

Fliy was late missed my connection ,. I had to find altery transportation.

When we landed, there was only one gate agent to handle three planes, including retrieval of carry on luggage. I was stuck in the jet way waiting on my carry on for almost 20-30 minutes. NOT GOOD

Flight delays for communication overall not a good experience uncomfortable on the plane. Person in front of me reclined his seat, putting them inches from my lap.

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.
