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.

Three hour flight so snacks and basic drinks unless you pre buy as usual. Didn’t do my emtertainment as was tired after 23 hours of travel. You have to use your own device on US flights if travelers aren’t aware so if you only use your cell phone that can be small. Crew are great.

It was very good. I love flying with Alaska air.

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.

Great crew, great boarding, old B-list movies, no free meal service, child kicking my seat back all flight long, early arrival, then 40 minute, confused wait for bags.

Appreciate efficiency and early arrivals. Missed video on such a long flight (DCA to SFO).

All 4 members of my family found the seats terribly uncomfortable. 2 of us suffered from back issues the next few days.

The crew forced all group F passengers to check bags because they said there wasn't enough overhead space, but when we boarded there was TONS of space. I was pretty annoyed by that.

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.

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.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

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

Multiple delays and not straight answer from the United team

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

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.

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.

We almost missed our return flight. We got to the gate one minute from closing the cabin door, and the agent got us aboard the plane! We are so very grateful!!!!!

Flight was delayed in phoenix by 1 hour. When Kenny got to minneapolis st paul, Kenny missed his connecting flight to Duluth on Sun country air. Sun country customer service did nothing to help Kenny get home to Duluth. We will not fly with sun country ever again.

When we landed in Minneapolis from Providence, the ground crew was unable to move the jet bridge to meet our plane because the wheels were frozen. We waited patiently on the plane for about 45 minutes while they tried to solve this problem. It was mind boggling that this would not be more quickly resolved, or anticipated, in a place where sever winter weather is the norm. We stressed about meeting our connecting flight to Portland, which we assumed would be our only option for that day. Fortunately, when we finally raced from our gate to the next one, that Sun Country flight had been delayed so we didn't miss it. We decided not to take anything but direct flights from now on, no matter how much cheaper.

No line to check my bag. Reasonable overweight fee. When the connection was late due to weather, the gate agent opened the door and let me on the second flight. The plane waited for my luggage transfer. My bag arrived on time at my final destination:)

I had paid for a seat assignment at the time of reservation but when I checked in the night before it wasn’t there. Had to purchase another seat.

So unprofessional. They changed my connecting flight to a time that made it literally impossible to make the flight with no way to contact them or reject the changes. When I missed the flight as expected, there was no one to be found at their ticketing counter and the phone support put me on hold for an indefinite time. Since they didn't have another flight that day, all sun country air personell had left the airport (this was at 7pm) and my only options were to get a hotel for the night and come back the next afternoon to hopefully get rescheduled or buy a flight with another airline.

I purchased an aisle seat but was put in the middle seat surrounded by families with small sick children (3). That can happen anytime and I was prepared. The ticket agent questioned why I hadn’t paid for my luggage and had to explain that 2 pieces were included with my ticket. I hate that nickel and diming attitude. Please inform your staff better.

I know the airline has been open for 40 years and the flight crew looked just as old. The flight attendants were not friendly and rude. They should think of retiring this crew.

The crew was friendly, but I only got a drink, no food.

Flight was late, boarding was a mess, families separated so they could make extra profit.
