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

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

While the flight itself was pleasant, the process of checking in was difficult. The line was long and our connection time was but two hours. When we finally got to the Hawaiian agent and told him that we were traveling on Alaskan Airlines, he told us we would need to go to a different terminal. I told him that another Hawaiian Airlines agent had directed us to him. I’m looking at our tickets, he noticed that the Alaskan Airlines flight was to be managed by a second party. He ended admonish us for not telling us so Rather than considering that we might’ve been right in the first place.

Only problem my credit card had over three pending credit card charges for luggages. I hope these charges do not post. I have already contacted my credit card companies.

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.

Plane left an hour late due to flight staffing problems. Only a 45 min flight, but it took 3 hours as a result, which left a lot of people disgruntled. No excuses. No recompense.

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).

Paid for first class, but the flight attendant for first class did the minimum required. She really ever came to pick up the trash, and never asked if we needed anything. Every person had to ring for the flight attendants if they wanted any extra drinks. When I went back to use the restroom, she was just sitting on her phone.

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

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.

Terrible and im avoiding them in the future. My initial flight was delayed causing me to rebook my flight and when speaking with the representative to rebook I explained this is the second time my flights were delayed and they did nothing to help me. I wasn't booked to comfort plus or given a voucher or anything. I was almost late for my meeting that I needed to attend on Monday because of the games delta played delaying my flights even more and putting me in the very back of the plane next to an extremely intoxicated passenger

Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

The WiFi didn't seem as fast as it normally is

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

The crew was wonderful and attentive. The seats near exit row were restrictive. Offer healthy snacks please

Delta is a premier airline so my expectations are most always met.

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.

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

I completely missed my flight because the first leg was longer than planned. I had to sleep overnight in the airport because no accommodation was provided and then sent to Trinidad in the morning with an anticipated 7 hour layover before my flight to Georgetown which was now with Caribbean Airlines. I tried twice with customer service to see if they could put me on an earlier flight which had seats available but was told it wasn’t possible.

First class felt like economy, seats were horrible, food was horrible, staff inattentive

EVen warmer in the plane it think it was 24+ degrees

The flying experience was great. The flight was on time with no boarding issues during a peak travel period. The short cut baggage drop and process was not smooth and efficient at Dulles.

Had a hard time finding my assigned seat. No attendants to assist.

Fast checkin with the self serve terminal, good communication at the boarding gate.
