Orderly boarding; engaged, attentive and detailed flight crew. Late out of the gate but time recovered during flight; super landing and deplaning.

Although delayed an hour, the gate attendants kept us notified and the rest of the trip went off with no issues.

All airlines should board planes back to front, instead of catering to higher priced tickets. The boarding groups are inefficient and delay takeoff time

Liked the attention and speed when getting wheelchair..........Was assured by phone that my needs would be taken care of and they were with my name.

Crew very courteous. Boarding was great. Slow to get baggage at Denver.

Sitting on the ground for 2 hours waiting for a gate wasn't fun.

The crew was great! Passengers were nice. Just an fyi that I heard several of them complain that the snack was not gluten free. Many people got handed the snack and then promptly gave it back to the flight attendant. Might be good to look into another option as such a high percentage of people in CO and WA are gf. Cheers!

First time flying with Alaska, and it went great. Thank you for a great experience flying to PDX.

I was pleasantly surprised to discover that Alaskan Airlines allows normal leg space in the economy class cabin, offers free movies and other entertainment programs via WiFi. The staff was friendly and worked hard to make this long flight enjoyable.

We have always flown with Alaska when we can. As they have great customer service. This trip we had to transfer to Air LINGUS in Denver to go to Dublin. That’s where things went bad! Our checked luggage didn’t arrive. The process to make a claim was way more complicated than it should be. It took 5 days to recover our luggage. The whole time we couldn’t talk to a real person who could tell us anything. The whole time Alaska blamed Air lingus and vis a versa. No one seemed want to help us. That was the worst part.

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

Flight was canceled, and no effort was made to help with rebooking, no hotel vouchers, no car transportation and minimal food voucher and most places for food were closed by the time the voucher was given. Waited for 3 hours for bags. Simply the worst travel experience I have ever had

My flight was 6 pm 6/6. Every hour they delayed it again - air condition issues then no pilot then the crew had worked too many hours and cancelled the flight at 11 pm. Sent customers to NJ a 45 minutes uber ride to a hotel. Had to be back by 5 am for a 7 am flight and again no pilot etc with another three hours of delays.

Delta flight was on time, seats were comfortable, and crew was nice.

Airline lost my luggage and set me back a day worth of travel due to having to stay in Denver to wait on my luggage

Nothing unusual. It was fine. I hate having to pay extra for my seat.

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

The helpful attitude of the staff, and being a wheelchair passenger everyone was helpful and understanding. The trip was made comfortable by the upgraded seat which was given without my request, that was a great surprise. Thank you Delta.

The flight attendants were friendly and seemed to like their jobs. I am not a high maintenance person, but they seemed to respond to people's needs and requests in a timely fashion with a smile.. I appreciate the benefits of complimentary snacks and beverages, as well as the relatively inexpensive checked baggage fee. (Although I would like it better if it were free! :) ) The only improvement that could be made to make the boarding process more efficient is to board the plane from the back. The alternative would be to board people with only a personal item first. This would reduce the wait time while others are stowing their baggage.

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.

Flight was late, the only reason I almost missed my flight was that my connection was also late.

We flew business fares. Was amazing. However, the check in didn't offer business fares preboarding which is less hectic. 8/10 due to this. Staff compared to Canadian carriers go above and beyond. Would gladly fly United again.

Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

Read the fine print. This was my flight home. I booked my flight for the quickest way home. Had a carry-on and a personal item. Same as my outbound flight. Apparently I needed to pre-pay extra for my carry-on. When I checked in, I was told that I had to check it. I said I’ll pay for it, and was told that this wasn’t an option anymore. They said I still had to pay $50 to check my carry-on. I told them I’ll pay whatever to just carry it in as intended. I was not allowed, so eventually I paid $50 to check my carry-on under a plane that was half full, with overhead compartments that were even less full. My white carry-on suitcase was practically destroyed getting from Idaho falls to Denver to Orange County. The low price air fair was a bait and switch. Got me to the gate, made me pay extra, then didn’t even allow me to pay for a carry on. Not to mention that I paid the $8 for WiFi that didn’t work. All to get my suitcase destroyed. I don’t think I’m going to even keep my Untied mileage plus membership and card. Apparently, membership does not have its privileges for this one.

I flew from Santa Fe to Denver to catch a flight to London and the transfer of my luggage on arrival at Denver to the London flight worked perfectly. The crew on the ground and on board for the London flight were so friendly and efficient.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The amount of seating is ridiculously small. Three points to consider Point One: Your in flight magazine needs to be smaller. Do you realize I can't even hold it in a reading position because of the limited space in front of me? It's a hangover from the past and if you want anyone to read it, it must be smaller. Point two: It is very uncomfortable for a lady to be sitting next to a strange man and constantly rubbing upper arms even when both of our elbows are within the arm rests. And larger men (whom I pity in this confined predicament) also tend to spread their legs into my leg space which requires me to hold my legs into a smaller position. Point three: The seats seem to position one's body in an unusually upright manner and the head rests push the head farther forward. I gave a small effort to see if the headrest could be removed but didn't want to break it or cause a scene with my efforts. I finally put my jacket behind my back to place my body more forward to match the head rest. The service was fine and I noticed ALL staff worked at smiling and greeting passengers. That was nice. No one likes to fly anymore as it is an endurance rather than a pleasure.
