Our flight was delayed for 2 hours as we sat at the gate while problems were fixed . The Captain made sure he kept us informed as each problem occurred and was fixed . The rest of the flight crew remained patient and attentive , which of course kept all the customers onboard calm and patient as well . My daughter just moved to Seattle and if this is the norm for this airline I will continue to use them for my future visits ! Elizabeth"

Cons: "My initial flight was at 0800; I got to the gate before 0800 and was told I couldn't board the flight even though it was still at the gate and was still before the flight time. I had to pay to rebook my flight, spent over $200 in rides to and from airport, had additional parking fees and was several hours late to work. I have many family members who work in flight service so I understand that employees don't like to re-do paperwork; however, being there before the flight time and being denied cost a lot of work time and money. I have always had great experiences with Alaska so this one was quite a disappointment compared to their usual great service. :("

Pros: "Crew was great and seats were totally perfect and comfortable"
Cons: "Nothing could have been better, except steak and lobster 🦞😃 Thank you very much for your ability to make customers welcome and comfortable."

Cons: "Smooth on time flight"

Pros: "Crew was gr8, seats comfy and space between seats was great, great space for legs"

Pros: "Seat was decent and only a $10 upgrade. Worth it!"
Cons: "Wasn’t clear what boarding group was up. I don’t usually fly delta so maybe I’m just not used to the system but something on the video screen at the gate saying where they were in boarding would have helped. I wasn’t the only one that seemed lost."

Cons: "Even the baggage was quick (highly unusual for Columbus, Ohio)! Everything went smoothly."

Pros: "The Crew on this flight was great and the flight was quick."
Cons: "The flight was delayed 3+ hours and Delta kept pushing the delay out further without giving any updates as to why it was so delayed, and when I inquired at the Delta desk at the gate the woman was very rude to me as she snipped that it was a mechanical issue."

Pros: "The crew was absolutely amazing!! So kind and helpful! The captain also took a beautiful path around Rainier during a gorgeous sunrise!! The seats were very comfortable and the flight was smooth even though it was a smaller plane (Skywest). I will absolutely fly Skywest again!"

Pros: "The crew at the airport was very courteous and helpful."

Cons: "No complaints"

Pros: "The crew was nice."
Cons: "This was an older, smaller plane and it had more leg room. Appears I’ll have to start checking Delta to see what birds flying the leg."

Pros: "This was our first time flying Delta and it was a very pleasurable experience. Boarding was very straight forward and the seats allocated comfortable. A surprise for us was being asked if we would like to move seats from the back of the aircraft to Comfort Economy (we think it was to do with weight balance! but appreciated very much none the less). The flight attendants were very professional and helpful, as you would hope all attendants on all airlines would be. We'd gladly fly Delta again anytime."

Pros: "On time leaving and landing"
Cons: "Every thing went well"

Pros: "Delta in general but , they let me stranded, i had to find a eay to fly home, they did Not help finding a next flight.. i missed my flight because of WX"

Cons: "Flight was cancelled"

Pros: "What an easy flight. Run very well!"
Cons: "The crew seemed a bit tired, but it’s the season"

Pros: "Flight was on a 787! Great plane"
Cons: "Food was mediocre for an international long haul fight, and was served by a completely indifferent staff! My prearranged seat choices were switched to a no recline rows and rebooking after a unnecessarily missed connection became 7 step comedy of errors ,aside from quality aircraft this felt like a budget operation."

Pros: "SLC ground gate crew was awesome."

Pros: "Everyone was friendly and the beverage service was very quick for such a big flight that was full. It was a great flight crew."

Pros: "Every thing went well"

Pros: "Helpful, and kind"
Cons: "Na"

Pros: "The flight attendants were incredible the flight was great the movies for good great for our flight"

Pros: "The crew was very cheerful"
Cons: "No entertainment and uncomfortable seats (at least for trying to take a nap)"

Pros: "Everything. I really loved that I could track where my checked luggage was, so when I arrived to my final destination I knew my bag was going to be there. The individual TV for my seat, so I could watch what I wanted. Having an USB port to charge my devices."
Cons: "Liked everything."

Pros: "Very Comfy plane."

Pros: "Tv on flight"
Cons: "Flight attendant skipped me for drinks"

Pros: "Great staff, polite and helpful"
Cons: "Small seats"

Pros: "Left reasonably on time, arrived a bit early, able to find overhead storage for my roll-on, even boarding in Zone 3"
Cons: "Very tightly packed; minimal comfort for the flight."

Pros: "Delta was smart with boarding early once they realized everyone had cleared security. Flight took off on-time and arrived early. The crew was excellent and exuded energy although it was the end of the day."
Cons: "I ordered a special asian vegetarian meal and it was just plain horrible. I had to settle for the cookie. It's nice that they serve a complimentary meal on the red eye flight but the quality of the food was bad. Entertainment options were also limited although they had some recent box office entries from last year. The leg room also wasn't great but that's expected in economy I guess."

Pros: "Nothing."
Cons: "The flight was delayed multiple times without any explanations, and we barely made our connection in Atlanta. Also, Delta used a commuter plane that really is more suited to shorter flights. It's okay, but that's about the best that can be said for it."

Pros: "The crew was nice"
Cons: "I didn't like the fact that I didn't get my luggage with me when I arrived to casablanca as I lived 4 hours away from the casablanca. I have to come back the next day to get my luggage. I was very mad about it.plus I noticed one of my luggage has been damaged so now I have to buy another one because I can t use it. It was disgusting."

Cons: "Our seats were assigned at the gate. We were literally seated in the last 2 rows of the plane. It was loud and tight and I would have NEVER booked those seats!! The whole fiasco was a complete turn off. And will make me reconsider booking through delta especially if it's a connecting flight!"

Pros: "Quick flight and we flew over Yosemite (where we recently hiked). Also, the free in-flight entertainment is such a nice addition! My wife and I had the seat open next to us, so it was very nice to have extra room in our row!"
Cons: "Nothing"

Pros: "The flight crew was nice and polite. They served drinks and snacks in a timely manner while on the flight."
Cons: "Flight was scheduled to leave early, the plane arrived, but they couldn't turn the plane around fast enough. We left the gat late, then pilot said we would still be arriving half an hour early. We arrived about 45 minutes late, and that was a problem because our connecting flight was due to depart now in 15 minutes. Lightning forced the airport to shutdown, which was great, we had a chance to catch our flight, but we were stuck in the airplane, and we couldn't get to our gate until the all-clear. I know this is not Delta's fault, but they did arrive quite late on a flight that, according to them, would be early. They also never communicated to the other flight that there were several passengers catching that connection. So by the time we had ran to catch our connection they had closed the ramp. Lightning hit again, and they shutdown the airport once again, so the airplane was still at the gate for about an hour, and they did not allow the 20+ passengers to board that plane, which was right there. So frustrating. The only thing that saved it was that our new flight was the new airbus, and although it left an hour and a half later, the comfort level was phenomenal."

Cons: "we had to get off plane and use another one. a hr delay but it wasn't that a bad .better to break down on the ground than in the air"

Pros: "Food was surprisingly good. Smooth ride could have been just good weather, but it was nice. We got in early!!!"
Cons: "Legroom was ok for me because I'm short. Others may have needed more."

Cons: "You pay extra to get the TSA Full background check, so you can breeze through TSA, with PreCheck, yet this Airline has a problem with recognizing it. 3 phone calls layer and a Visit to their Costumer Serice Desk, and none of them can figure it out. Uhg again."

Pros: "Perfect, but I did upgrade to United's business plus."

Pros: "Aisle seat."
Cons: "They made my dad check his bag even though there was space."

Pros: "Worst flying experience ever"

Cons: "I was informed today that one of my checked bags was picked up by another customer who eventually realized it was not her bag. She brought it back to the airport and refused to turn over the bag until the airport compensated her. (How this happened I have no idea because I stood right by the entrance of the baggage claim and never saw the bag come out). The customer refused to return the bag until the police became involved at which point she agreed to write a note confirmed she did not steal anything. The bag then needs to be sent to me in 2 days and I'll have to verify myself that indeed nothing was taken from the bag. I'm very concerned how this individual came to be in possession of my bag considering, again, I stood right at the entrance of the baggage claim conveyor belt from the time it started to when it ended. As a result, this experience really made me feel frustrated and violated."

Pros: "on-time! Even a little early!"

Pros: "By bag was broken when I got to my final destination. It looked like they played football with it. I'm filing a claim with United Airlines"

Pros: "Please address the lax enforcement of one carry-on and one under-the-seat bag/passenger."
Cons: "Overhead compartments were full by the time I boarded so my bag was taken and tagged, as was several other passengers. I noticed upon arrival in Hartford that several passengers had 2 bags in the overhead compartment and their coats as well. If you have a policy of one carry-on and one under-the-seat/passenger, why isn't this enforced? It is not fair to the Group 4 and 5 passengers that there is no room in the overhead compartments and they are forced to relinquish their bags. Furthermore, this results in them having to go to the baggage claim area and wait for their carry-on. This added a half hour to my time and my ride had to circle the airport waiting for me to come out."

Pros: "Overall I arrived at my final destination in one piece. I'm satisfied :)"

Pros: ":("
Cons: ":("

Cons: "The airline checkin is terrible and time consuming!"

Cons: "Never made it because of stupid United"

Pros: "The pilot got us there safely. Good deal of turbulence."
Cons: "Stewardesses were rude to many. Chit chatted with each other whole way, ignored passengers. "Too turbulent" to serve us a beverage, which was okay. Except first class got full service. Wrong."

Pros: "Smooth thru0"
Cons: "O"

Pros: "I loved my extra legroom and how high the ceilings were."
Cons: "All these people bringing on all these carry on that don't fit. I don't believe they would all fit. This makes boarding twice as long and the plane gets uncomfortably hot. For someone like myself who only carry a handbag this is very annoying. I feel the airline should seriously measure the actual size a bag should be to fit and if it's bigger then no go. I also thing checking bags at the door should be charged just like we pay to check. People seem to be trying to save money to check at the door. I find this a disservice to people who do follow the rules. And delays are take off."

Cons: "Check in"
