It was all great all around. Will travel with Alaska next trip.

Boarding was quick and easy as always the crew is on their game as always I always have an enjoyable flight so I’m good.

Need to get on train for second flight it’s much nicer when all the gates are together for obvious reasons

Cramped, crowded aircraft. Poorly organized boarding. Tasteless crackers to eat. 40 minutes late. A standard US air travel experience.

It was my first time flying Alaska Airlines and first time flying from Santa Rosa airport. The staff was very professional and friendly. Their instructions were clear and any question was answered satisfactorily. My seat was comfortable and the in-flight beverage service very adequate for the duration of the flight. We arrived ahead of the scheduled landing time and deplaning was simple. I look forward to flying with Alaska again.

Flight attendant took my carefully folded coat and flung it across the aisle to the bin across the way. Where one of the passengers rescued it for me, because that just wasn’t right!!

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.

the flight was delayed twice and then delayed from taking off.

Crew was very good. Problem was not Alaska Airlines’ fault, there was a horrible, squealing, screaming kid near me.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Seats are much much more comfortable than United, which is what I usually fly

Logan airport construction meant that boarding was chaotic crowded and delayed

If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.

Only one side of the heafphone jack work. Crew was friendly and helpful.

Great. Flight departed early and arrived early. Deplaning and baggage claim ww were quick.

Don't waste your money or points on first class. Delta first class is a joke. The seats were rickety, the food was awful, and nothing worked, wifi, my light, the power plug - and it was dirty - the fold out table was gross. For 2-3 hours, tough it out in Economy.

They separated our seats and moved us to the back of the plane. Hundreds of dollars and thousands of miles used and this was my platinum member experience.

Flight was changed from departing from Boston to departing from Detroit.

AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.

A bit rush for transit. Food and entertainment are not available

The gate was too far away for the connecting flight

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.

Boarding always seems a bit chaotic. Seat spacing could leave more for leg room.

Not the best. Mean. Didn’t give any value to me being a united silver member and lots of attitude.

Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗

Excellent from start to finish. All staff members were amazing!

Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.

Cancelled flight with no specific instructions to get a boarding pass for another flight. The whole flight of people were in line for an hour because there was only 1 person to help at the desk. This was unusual for JetBlue.

It was too hot in the cabin. The AC did not help.

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking

It took 1-1/2 hours to get our luggage after we landed. That to me is unacceptable

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

Overall was excellent. Will definitely us JetBlue in the future.

I rate it is good we had a 4-hour travel delay at one point but JetBlue gave out food vouchers and travel points credits for another flight so they try to make up for it

One bottle of water and a package of cookies for comfort plus. We had to literally beg a flight attendant for an extra bottle of water later in the flight due to feeling dehydrated.

Everything was fine. Flight boarded and departed on time. Seating was spacious enough for my carryon to fit under the seat in front of me. No complaints at all. Flight even arrived early.

Flight boarded from Gate 39 at OGG, the farthest gate in the terminal. There were no Hawaiian themed amenities for the flight. The first class service was mediocre at best; I received not special welcome or recognition as an executive platinum member of American Advantage program. The flight attendants were more concerned with their cell phones than saying "thank you" to the passengers as we disembarked. Fortunately, the flight arrived at LAX a few minutes early.

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

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

This flight didn’t happen because AA agents didn’t let us board the flight

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.

The service and food needs to improve to catch up with other international flights

Would have been good to have a meal since it was a 5.5 hour flight

We boarded after several delays due to mechanical failure and a gate change. The seat cushion in the exit row was very compressed and offered no cushion, making the four-hour journey reasonably uncomfortable. The WiFi worked for a few people, but for most, it did not, and you cannot get entertainment unless you can connect—American Airlines flights do not have seatback screens, and you must use your mobile phone.
