It was cancelled due to crew. I missed a special family graduation due to this

It was cancelled due to crew. I missed a special family graduation due to this

I had never flown Alaska Airlines before. I’ll definitely use them again. Seats were comfortable and roomier than expected.

Seats lack shoulder and elbow room. The lady next to me was short and slightly heavy with knee problems, she kept jabbing me with her elbow while playing her game on her phone for 2 hours, the duration of the whole flight. It was frustrating and annoying! I was in the middle seat, there was no space to adjust to avoid her arm jabbing me.

I like the big picture of the Eskimo on the tail of the plane.

Being seated next to the engine was awful! I was nauseous the entire trip from pre-take-off, flying to landing. The engine vibration was very strong!

The crew was the best I’ve had the experience of flying with. A misbehaving child was making things difficult for me with bopping my tray table, taking my snack, and continually tapping or bumping me. The crew quietly and respectfully moved me to another seat, and thanked me for my patience. They couldn’t have been more kind. Their professionalism really stood out to me and I am more than happy to leave a great review for them!

I would have appreciated notification that our flight was moved to another gate LAST MINUTE so that we would not have missed it. We got no such notice and had to spend another night to catch an available flight in the morning, which was huge inconvenience. We will never fly Alaska again.

Flight was delayed 2 hours. It was too cold inside the cabin. My seat mate had no jacket so she was shivering the entire flight. The stewardess says there’s no available blanket.

The airline was way too cold. We were freezing, I don’t know if that is normal. Overall it was pretty good flight. Always flown Alaska Airlines and I am not changing.

Mediocre is best way to describe. Bare bones narrow seats, Dirty pulldown tray, unfriendly cabin crew who were in a hurry to serve tiny drinks and tiny snacks. (Compared to much better Hawaiian Airlines experience, .. no comparison!)

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

The Flight crew didn’t serve us until about 1.5 hours into the flight because of turbulence but after it ended it was fine to move around. They served us water only and snacks and then NEVER, NOT ONE TIME came through to collect trash until right before landing about 1.5 hours later. There was absolutely no need for that. They crew was just standing around talking and visiting with each other and really never tried to see if we might want something besides water or even try to come pick up trash. This is VERY unusual for a Delta flight but it was not what I would have expected for a 4 hour flight.

Everything went smoothly. I didn’t like that when I booked in the main cabin my wife and I weren’t seated together. One would think when booking on an option that allows picking your seat. They would put you and your travel partner together. Had to call to get it sorted. They did fix.

They did a fine job. Can't wait to use Delta in the future.

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

Seats in first class on the E175 recline too far back. I was in 2A, and the man in 1A fully reclined almost the entire flight. It took 6-7 inches of space away from me and made it very difficult to work on my laptop.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Overall fine but both ways for this trip was delayed.

I had back trouble prior to my flight and everyone was great about helping me.

My tv was broken on the flight which is disappointing when you pay for a seat and expect a service

Always delays from Boston to Salt lake but this time was very long. Don’t understand while they board the passengers and then make them sit in the plane

Service for food to our seat was a bit slow. Snack choices were just pretzels or baked chips. My seat cushion was not attached. Other than Barbie, video choice were not very good or current.

After we landed, we were held on the plane for 30 minutes. There was no one at the gate once we landed and we forced to sit on a plan that had already over an hour delayed.

almost 4 hour delay as they over booked and had to wait for 8-10 volunteers to agree to travel next day.

Old plane. No outlets for laptop or phone. Seats worn out. Area around seat dirty.

I loved the flight and the crew. It was comfortable and smooth.

The crew was openly hostile and condescending to the customers. They spent the majority of that time in the rear talking and seemed really agitated when people asked questions. I heard five different people told that the information they requested was in the handout or safety brief.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

Flight was delayed due to the late arrival of the catering truck, which is quite unacceptable. There was a beverage service, but no pretzel, or cookie, or nuts were served in coach.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

No lounge access with “United First” ticket. False alarm about late flight, jeopardizing connection. Wrong meal. Loose power socket would not hold plug, could not charge device. In-flight access to text messaging did not work. Toilet seat on plane would not stay up.

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

My husband and I pre-ordered our food, but they did not have my husband’s order, and my cheese plate was very average. I asked for a blanket and was told they don’t carry blankets on domestic routs. The flight was on time and smooth!

There were delays on both ends. It made it less than excellent. This plane was great though

Worst experience flying American Airlines. I fly with them often, so I was super disappointed in the service I received at gate 30 in LGA on May 24, mid-day. The flight was delayed twice. I was patiently waiting in the American Airlines lounge when I received the notice on my app that the plane was boarding 45 minutes before its newly re-scheduled take off of 4 pm (from the orginal 1:45 pm then 3:00 pm). It took me 5 min to travel from the lounge to the gate and when I arrived there at 3:20 flight gate attendant told me the flight had closed and that they announced for passengers multiple times. I showed them the notification on my app and they were really rude and unempathetic. The person who rescheduled my flight at customer service wasn't any happier but was at least helpful in getting me on the next flight.

Everything was great except for the wifi was junk. Crew was super friendly and helpful

Attendants were rude. Scowling. Seats were miserable and we paid extra.

Fight crew was not very attentive and the bastions were gross!

Our flight was great we left Kona earlier and got into LAX almost an 1hour earlier as well. LAX AA is in repair so to get out and found our bus to get pick up was a bit confusing.

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

delayed delayed delayed. was supposed to have a 2 hour layover and very nearly missed my connection.
