It was awful. I will never appreciate this type of connection where i have to wait 12 hours which turned into 18 hours due to Alaska's delays after flying over 15hours already. The 15 hours already made my body suffer as soon as I deplaned. I struggled to breath and was about to faint,but being alone, I tried to hold on my carry on luggage I wasn't able to take it anymore, so I informed the airport people who then assisted me. My husband had to book me a $200 hotel room so I can rest. I stayed for only 4 hours in that expensive hotel in order to catch my 8 in the morning flight to Spokane only for it to be delayed until 2:17. We finally left LAX before 3pm. Alaska was also inconsistent with their gate assignments. Our first gate was 64A, after the delay they sent us an email that the next gate was 68,but the arrival and departure board showed gate 60. When I asked the desk 60 agents, they said it will be gate 61. All these experience contributed to my exhaustion and stress which affected my heart and well being.

Technically this was the flight where they lost my bags, but I already explained that on the review for my connecting flight, so I'm not gonna do it again.

Alaska is consistently the best in all categories. Excellent airlines and employees

On time, friendly and professional staff and crew Very nice new terminal in Spokane

The flights left both airports on schedule. The flight from Idaho Falls to Seattle was a typical commuter trip. The flight from Seattle to Maui was not good: It was too long for a flight in a single-aisle plane and too cramped. I kept asking myself if I would ever visit Maui again if airlines continue to run this long flight like a typical short commuter flight. I am not looking forward to the trip home.

Flight was on time. Staff was polite and efficient. The snacks were good - only an hour and a half flight. No entertainment but didn't expect that. We brought our own things to do.

Everything smooth (including the landing) and on time. Easy. Thanks.

Flight cancelled. Bad service at customer service line. Missed dr appointment

The boarding in Idaho Falls was terrific. The plane was a bit sad, and the snax were subpar. Mostly, I was just grossed out by the Alaska gates in Seattle. EW! Smelly and cramped and dingy!

It was a short flight with turbulence, so we did not get any drinks or food, and there really wasn’t enough time for a movie.

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

My flight was cencaled due with the bad weather on Sunday the crew was poorly mistaken my luggage supposed depart with my flight instead I didn’t have my luggage for almost 3 days the website is poorly respond to my complain until I have someone to do it my connection smooth their not even respon or email me even the have my luggage

8 hours late and the plane smelled like urine, that smell in the morning when your child wet the bed in the night.

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

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

Flight delayed about 2 hrs so it made it a VERY late night

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.
