It was awful. We experienced turbulence for nearly the whole flight. Then when I picked up my luggage, two of the wheels were torn off. Worst flight ever!!

It was awful. We experienced turbulence for nearly the whole flight. Then when I picked up my luggage, two of the wheels were torn off. Worst flight ever!!

I like the short flight to Seattle and San Francisco. The boarding was fairly easy and the flight was as to be expected. The in-flight entertainment could be improved with wifi options. Paying $8 and then losing internet access and being told that flight attendants didn't want to serve beverages and snacks on board was disappointing because they didn't want to move a cart up and down the aisle blaming it on air turbulence which wasn't a problem.

Not great. The flight was delayed, then when we were on the plane we spent over an hour taxiing before take off. We arrived very late and it took a long time for the luggage to arrive. I wish you all Happy Holidays though.

It was comfortable, the food was mediocre. Tasted like microwaved food.

My flight was delayed. But it was during holidays so you kind of expect things like that to happen. I am not a frequently flyer so I am OK with that. But none the less, once the flight started, it seemed to me like it went fast. 😊

The planes were clean! The crew was good The boarding in Seattle was not good because the accent of the woman and the low volume of the speaker made it impossible to hear.

The entire trip from Bellingham to Seattle and from Seattle to Boise, Idaho was very very good and timely

What has happened to your airline customer service? We have to pay extra for everything now, except water, coffee and pretzels. A 6 hour flight and pretzels are free? Baggage is fined/fee Pick a seat is fined/fee A better seat is for bed/fee A meal is fined/fee Baggage over 35 lbs is fined/fee **When did get shamed into being like Spirit or Frontier? I'm rather disappointed in you.

The flights were on time and catching the connecting flight was a breeze. Next time I won't carry such a heavy carry-on without wheels!!

Would like to see more consideration of older people. I have issues with being on my feet and walking too far. You put me in the last seat on the plane. Way in the back. Other than that everything was vey good.

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

Newer plane, relatively easy boarding, not a full flight and was told that we could not be moved up because of weight and balance issues. Otherwise, a very good experience.

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

The seats are uncomfortable, feels like a small seat pad on plywood.

My husband is very tall and we generally fly Delta Comfort. We used our companion benefit, and our seats were coach and extremely uncomfortable........ horrid even

My seat had no padding, it was literally plywood with a plastic cover. I could not change seats on my 10 hour flight. My excitement for this trip helped me deal with the pain.

I notice that every time I fly delta or any American carrier, the staff seem tired, overworked, and not at the service level I’m accustomed to in Asia. They frequently crash into my arm when coming down the aisle. Food is shoved at my face with no greeting or verbal cue. The food portions seemed much smaller than usual and didn’t see much wine or beverage options. This is comfort plus? The plane was old and tired. The bathroom was dripping with mineral stains after a long lack of cleaning. The power socket did not work, although the USB output did. I really wonder why I’m flying Delta, I think it’s time to switch to ANA.

The flight was great. The crew were a little terse about the size of my bag. It fit fine.
