They changed our flight to Kalispel and we ended up getting there close to midnight. The return flight got changed as well by a few hours. Then of course some issues with the plane and we were even later. First time flying Alaska, may be my last.

They changed our flight to Kalispel and we ended up getting there close to midnight. The return flight got changed as well by a few hours. Then of course some issues with the plane and we were even later. First time flying Alaska, may be my last.

Missoula is a great airport. Desk and gate crews were very helpful and friendly

The flight was delayed out of BIL so many times that I was not able to make my connection. I was rebooked for the next day, losing a full day of my trip. I still have not been compensated as promised.

2 hour delay. Then some luggage was unloaded at 1baggage claim #7 then without notice the baggage claim was changed to #12. No one informed the passengers they were changing baggage claim turnstile. Several of us waited for 90 minutes after the 1st turnstile stopped and changed to other flights luggage.

Easy check-in. Good customer service. Had to check carry-on due to lack of overhead space. Wish the airplane was configured with more overhead area so this doesn't usually happen.

I liked that the crew was friendly, we left and arrived at near scheduled times, plenty of on-board crew to handle the cabin service for the flight and I found the price of my airline ticket to be excellent!

Had no way to see what gate came in on or what gate connecting flight would take off.

Planes were on time. Pilot kept everyone updated. Crew was friendly and helpful

I have mobility problems and requested wheelchair assistance in Seattle and Anchorage and none was provided at all. Very disappointed. Only one gate agent in Seattle asked if I needed assistance boarding my flight in Seattle.... and only after three gate changes.... requiring even more extremely painful walking without assistance.

My travels went as smooth as they probably could have, I expected delays upon delays but to my surprise even with the small delays I had I was still able to make all my flights. Thanks -Josh

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!

Prior to takeoff, the pilot told us there was a possibility of not being able to land and going to Portland. Well that happened, we took off and then did 8 loops around Spokane before the pilot told us we ran out of fuel and had to go to Portland. So for a 35 minute flight we have now been on the plane for 3 hours (boarded at 6:50 am and landed in Portland at 10:30). Then, we just sat in Portland's airport with no updates of when we can start heading back. All of a sudden, our pilots and crew just left, leaving us stranded in a different city and state. We continued to sit in Portland until we finally got a new crew assigned and boarded the plane (This was from 10:30-2). We then sat on the plane for an additional hour before take off because they had to count us multiple times. We finally landed in Spokane at 3:55 PM. So a flight that should have taken at max an hour took us 10 hours and we missed the majority of the recruiting event we went for.

Staff was great! Kind and cordial! Middle seat row 28 seat B has a hump in it. Trays were getting stuck when putting down and up. Good flight

Didn’t make the flight. My connecting flight was an hour late and I missed the flight. You rerouted me thru Atlanta and I arrived in Rome over 10 hour after my original Rome arrival time. You also left my luggage in Atlanta and it took you three day to get my bag to meI spent 4 days in the same cloths, I had packed my prescriptions in the lost bag and went 3 days withoutMy heart meds.
