Flight 351 SEA to BOI was terrible. We got to cruising altitude and I needed to use the restroom but the fasten seatbelt sign never came off. There was no turbulence and I'd felt the plane level off so I stood up to use the restroom about 15 minutes after we leveled off. The stewardess went over the intercom and said I needed to be seated because the captain hadn't turned off the fasten seatbelt sign....Which... Fair.... But not five minutes later she went and used the bathroom. Felt very unprofessional to leave a paying customer with a burning urethra for the entire flight and bark at them to sit down and still use the bathroom yourself. They never did turn off the seatbelt sign.

They never did turn off the seatbelt sign.

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!!

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.

There was an issue with water that led to us not having potable water onboard. They dumped the onboard water and we were two hours late taking off.

The flight from San Diego to San Jose gate 28A The two persons working there didn’t even turn on the display board. The display board saying to Sacramento. When I asked she was rude and showed the board . Then he realized And changed. Every one was confused because we are running late to catch that flight coming from IAD. Very irresponsible staff.

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

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

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 ;)

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

Flight was cramped with every seat taken. The food was fine, nothing crazy to write home about. The plane felt dated and needing some TLC, the button for the window shade didn't work and there were no AC outlets to use. When communicating with staff all except one nice lady never seemed happy to help me almost like I was bothering them when asked for things like a glass of water or a snack. The flight was overall fine. It did what was needed which is get me from point A to point B. But it certainly was not special. I don't expect much in economy but I believe economy on a host of other airlines is more memorable and better experience.

The flight was heavily booked so boarding was a lengthy process. The FA’s were rather abrupt during this process but became more gracious as the flight went on. Breakfast (puffed pastry and chewy sausage) was pretty horrible but there was fruit and yogurt which they didn’t mess up. Overall it was fine.

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

Liked nothing. As per previous segment it was delay delay delay.

Wonderful as usual except for other guests that were unruly and not kept in check by the Crew.

The flight was initially delayed, then cancelled. American Airlines says the cancellation was weather related, though the actual weather was not bad in both Washington and Providence and between. There were very few cancellations that day. In fact, AA2120 from Washington, DC to Boston flew with a minor delay at about the same time. So, the weather somehow affected only this particular flight AA5230. The next available flight was the following morning. The American Airlines refused to reimburse accommodation (hotel at DCA)

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.

Fine. On time, cabin service was fine, bag arrived. All good. Flying into DCA so did not collide with any helicopters, which is also good. Horrid incident that could have and should have been prevented.

Good experience but the snacks are not gluten free, so I cannot eat them.

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.

Standard. No different than a discount carrier on a short trip.

Everything was great. Boarding, early departure, early arrival, and deplaning were smooth. Smooth flight.

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

I blame kayak for my last trip to dca. Kayak cancelled my direct flight and put on a one stop flight and made lost whole day from my vacation and had not even refunded my ticket.
