I was assured by the phone rep weeks ago this had been cancelled!!

They lost my bag and 24 hours later have yet to find it

3 of the 4 legs of our trip the crews were awesome! 1 leg the trip attendants were rude & dismissive, didn't even greet us when boarding even though both myself & my husband said hello directly to them when we boarded.

There was an issue with the plane and it was late getting in. This caused me to miss my connecting flight from PDX to BOI. I had to ask if they would provide me with a food voucher and they did but didn’t seem to concerned about my delay.

I didn’t go, and can’t use a no refundable ticket.

Fine. But given how empty the flight was, I do not understand why my dog, in its carrier, could not be placed on the seat next to me (which was empty) rather than on the floor under seat. This seemed like overkill on the rule following by the flight staff.

The staff was so kind and friendly! Boarding was efficient and communication was timely. I would seek out flying with Alaska Airlines in the future.

They closed boarding too early. They made me pay extra to continue flying with them. Their customer service is non-responsive. I used to love Alaska Airlines, but they've definitely regressed.

The vibe and energy of the Alaska staff on ground in Redmond is some of the best we’ve seen!

It was a good flight, short so there was no food or water service

Requested an aisle seat at the gate and got it. The staff so friendly

Flight was very delayed so I was able to get on an earlier flight via stand-by. Crew communicated effectively around delay and worked to make customers comfortable. Wifi was ok, streaming TV was great. App functionality broke down once I was moved to stand-by on earlier flight.

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

It was as good as it could be. Flying is not a pleasant experience these days.

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors

Got on the plane and sat there for an hour before departure.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

Cramped seating for me. Luckily it wasn’t a long flight

It was easy to board, and the staff was friendly and helpful. What could have been better is that I shouldn't have to pay extra for a seat that doesn't recline.

Was on the plane sitting longer than the actual flight in air was, boarded at 5:45p and didn't take off until 6:50p flight was only about 30 minutes long. Just was poor experience will booking more with American Airlines.

The couple in front of me were constantly talking over the announcement from the captain and this was annoying me.

The first leg of my trip the Republic Airlines aircraft was late due to a maintenance problem. Then I called United to reroute. Their reroute airline lost my bag but found it and returned it two days later. Hopefully my return trip home is better.

There was not even a single time where united airlines from lga has made to the gate straight , 1 hr if delay today

Takeoff delayed 2 hrs. Boarded on time to find we were missing part of the flight crew. Then informed that they had loaded too much fuel. Spent 1 1/2 hrs sitting there burning off the excess, which included a couple of laps around the runway until we were light enough to fly! Ridiculous!

Requested for warm or hot water because of throat pain, it was denied. The entertainment system was hung, requested the crew to turn it off, instead of turning it off they rebooted the device. It was stuck again, no one bothered to check.

Horrible on the chicago end. They change hates then there is a plane at the new gate so we can’t pull in. Then that plane has mechanical issue and needs to be pulled back to the gate but we can’t get to another new gate due the other plane being in the way. Horrible gate management which will cause many customers to miss connections.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

I liked being upgraded to first class. The flight was a redeye, so I did sleep most of it.
