Great ground staff - made boarding smooth for my family , helped us be seated together. Cabin crew was very friendly.

Late to board and late to get off the plane too

Love how smooth Alaska operates in Portland. The bag check was super smooth and my bag was on the carousel before I even got there!

Airline boarding experience could definitely go better, though that's not limited to Alaska Air. Couldn't get logged in to the plane wi-fi.

They cancelled our flight at the last minute, then reassigned us to a flight where we were in middle seats. Their "food" was a set of crackers.

On time flights, their system for pre-registering what food you want is buggy and missed our food order twice.

Crew was courteous respectful and attentive to request from passengers.

Great m. Special kudos to Tamara at the check in counter Kodiak on Sept 6, 2024!!! Very pleasant and helpful, especially at the early hour of the morning.!

Smoothest landing ever, great flight. No window was a bummer, I checked seat guru but it didn’t say anything about 11a not having a window, but my wife and I had all three seats to ourselves and it was a night flight so no big deal.

Ground crew at SFO checking didn’t print my boarding passes for my second leg … creating a full mess at LAX So the desk asked for my passports, and was able to check in my luggage up to the final stop, they never realized that our journey was made up 2 legs.

In thirty years of traveling, mostly with Delta, this was the worst day ever.

The flight was so late that I had to change connecting flights, turning a five-hour trip into a fourteen-hour nightmare.

I am so shocked at the service in first class. We were not greeted or offered a beverage for 45 minutes into the flight. She did however have time to write a long note. I just wanted a snack and something to drink. We were never offered coffee and the snacks came after dinner? It was the oddest flight I have ever been on. The gentleman next to me got up and gave our dinner box’s to the flight attendant and asked for a second glass of wine for each of us. Our dinner boxes sat on our tray for 20 minutes. She was rather distracted. He then asked another flight attendant for wine… finally we had a second glass. I was trying to give her some grace, she also told the man next me we couldn’t have any more wine because we drank it all… after landing the seasoned traveler next me ask for her employee number. Then it was a mutiny! She was refusing and it got tense. The captain came and asked what was happening, the flight attendants totally gave a biased account of the fact. The captain told the police the man I was seated next to was intoxicated! That was completely inaccurate and it really escalated things. I policeman found me at the luggage carousel to verify the facts. The flight attendants made false accusations that he touched them! That never happened. It was a very poorly trained crew. I am so anngry and shock by the entire experience! It was terrible service! I would like a refund for what I paid to be in first class and the most uncomfortable flight ever. I always fly Delta, it has been wonderful. I was so flustered by the entire experience! Please give me an update on this matter! Thank you, Kelle Myers

It was reported to the passengers that Delta failed to schedule the crew properly. This error caused the pilot to show up about 30 minutes late. All in all Delta's inability to take care of this basic function resulted in about an hour delay.

Late departure due to large number of wheel chair patrons. Used to having a box of snacks to select from in comfort plus. The flight attendant just rattled off what was available and asked us to pick. Felt rushed and uncomfortable. Seat was great. Prefer having the screen on the seat in front of me instead of having to pull it up from the seat side. Lots of room for my carryon under the seat in front of me.

The airplanes were so old and out-dated it was terrifying to fly on them.

It’s was good. There’s so much room for improvement though. Since the plane was small, there was no entertainment but for years now, the most jarring aspect of travel is the lack of tasty snacks.

The important things including boarding and the flight being on time and safe were excellent. The disappointment comes from the comfort and amenities. Was misled by the "availability" of inflight internet- there is an extra cost. The tray table was broken, the bathroom door stuck and flight attendants were competent but not very friendly.

The Pilot was one of the best I've had, very informative about turbulence and got us to our destination early

The Gate Attendant @ Gate B36 was rude The flight was good but the entertainment system was not functioning as expected. The snacks were ok but could be better The flight crew was excellent.

Delayed over an hour due to paperwork not being filed correctly. Forced to change planes.

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

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.

The flight attendant was very kind and offered my son a snack for free.

Flight was quite late as there was no pilot Crew is usually excellent, this flight not as good as usual there were more mistakes, slower and less friendly service But honestly the aircraft was too cramped and uncomfortable for a 4 hour flying get so, do to the aircraft liability the very best you could ever do is mediocre.

To san Francisco it was ok. From sf to Manila it was horrible

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

The passenger in the row in front of me was listening to a political speech on his phone at full volume with no headphones and it was disturbing all of the passengers around him for several rows. I asked 2 of the flight attendants to speak to this passenger but they only shrugged. It was obvious that they were afraid there might be conflict and would not say anything. I had to take it upon myself to tell the passenger that he needed to turn it off or wear headphones as it was disturbing everyone around him not wearing their own headphones. I was very disappointed in the United flight attendants.

Flight was ok. Unfortunately it was a Boeing 737, which is a cramped / tight airplane. I prefer the Airbus as they are a more comfortable flight experience.

We fly to Ecuador frequently. Checking in is usually a hassle because most United agents take some time before they can verify that my passport doesn't require a visa to Ecuador. This time the process was even longer due to the cyber attack. But she was really nice to us. So glad we brought plenty of snacks to supplement the 3 flights from SEA to GYE.

First time flying with them and will definitely fly again in the future. Crew was so nice and friendly, fought was seamless. They are simple planes, no entertainment, but it’s fine for a short flight or if you have personal devices Rates are competitive, and they did so well with keeping the flight on time after a tropical storm, where other airlines had delays and cancellations.

They boarded passengers that sat in the back of the plane first, making boarding very efficient.

I didn't even take this flight. My plans changed and I couldn't get ahold of customer service and the website kept breaking down during the attempt to change the flight. I wound up taking another airline entirely and eating the cost.

The worst flying experience ever 3 delays. No accommodations. Had to deboard the plane after being delayed.

Posted a 20minute delay but didn’t delay at all. Caused boarding issues and confusion. Also, didn’t release baggage. Took over an hour and 20 minutes to get luggage.

Flight was good, boarding was a breeze, flight attendants were friendly and professional. There was a medical issue with another passenger and the crew handled it in a calm and professional way.

The net issue I had was with the gate agent. We had added a carryon to our boarding pass when we checked bags. When I got to the boarding gate the agent was rude asking why I had a backpack - I said I added it - even had an orange tag on it. She ripped my tag off and swung her monitor around to show me how she was right- saying it isn’t wasn’t listed - only a checked bag. I explained again that I wasn’t sure what the issue was but I wouldn’t have an orange tag if I hadn’t added it. Then she finally checked my husband’s boarding pass and found that the agent at checkin had added my carryon to his boarding pass instead of mine. She sent me on my way without my orange tag. Was a bit embarrassing for me the tone she used with me assuming I was trying to get away with something.

Great seat space. However food and drink prices outrageous. Jabbing to pay for a carry on bag or stuck paying at the gate too much.

Every Allegiant Air flight I've ever taken has been delayed. This flight was delayed a full 2 hours. It was excuse after excuse after excuse. It was a flight from southern Florida. They made us board the plane on time, but made us wait for 2 hours on the tarmac. Because the engines were kept shut off, so was the air conditioning. One can only imagine how hot the air was in the cabin over those 2 hours on the tarmac, while in the hot Florida sun. Just terrible.

Worst ever! Flight cancelled supposedly for weather even though we k ow of many others who flew into Bangor same time no problem. At the airport there was no customer service at all just refund and no possibility of rebook for 3-4 days. Aweful won’t fly with them again!!
