2 FLIGHT DELAYS? what an inconvenience to stay @the airport HALF THE DAY😳from 1pm till boarding @ 4pm pass 😠exhausting !

Awful experience. Flight delayed over night due to technical issues. Had to speak with 4 different reps and beg for hotel and $12 meal voucher. Asked for a sit upgrade at the gate, rep said not available, with the comment it would not be fair to other passengers, although I am a AA and cc member. Were packed like sardines in economy for 15 hours, while the were plenty empty sits in 1st, business and premium economy. Pretty terrible.

boarding was late worst was going back LAX to SFO delayed not once ? but TWICE😡I was at the airport practically almost 5 hours of previous time , very inconvenient! i would have spend longer time with family , I was wanting to avoid TSA line? but it just got me to spend unwanted time @ d airport

You no longer give receipts for baggage at the counter. And it is next to impossible to get it on your webpage. Spent 20 min trying and gave up... I need receipt to submit for reimbursement and don't have time to waste on your poor webpage Disappointing .....

The flight was jumping between being delayed and closer to schedule about 5 times. Alaska air website showed incorrect times while google had latest info. This panic was horrible to deal with.

Flight was delayed - we left at 11:30 pm instead of 10:30 and it was extremely inconvenient. It affected both the day of the flight and the next day

Plane boarded and left on time or very close to the stated departure. Arrived on time. Staff was subdued. Could not hear the flight attendant too well. No announcement from the pilot which is always nice. Biggest complaint absolutely no little snacks! But the important thing is we left and arrived on time and we survived.

Crew was not happy to be there and neither was I 😭 well at least the lady that helped me.. I was stuck in the middle seat between two men. Totally my fault since I didn’t pay a fee to select my seat though. I recommend paying the fee even if you’re in a budget. It’s better than being placed aaaaallllllll the way in the back next to the smelly bathrooms. The seats didn’t recline either!! It was a red eye flight so I got no sleep whatsoever. Ordered a coffee and it tasted like…. Let’s just say it was horrible. I had to to return it to the same crew lady and she looked at me like this girl…. Sorry but I was not going to drink that- please take it back!! Oh and lastly, my luggage was completely broken and damaged. All wheels were missing by the time my luggage came around in the luggage cart. Lmao. Overall poor experience to say the least. Tickets were cheap though😂😂😂

Overall it was good. There was a delay in departure, which is why I did not rate it as excellent.

Departing flight to San Diego was delayed. Return flight from SD to SBP was delayed. Not terrible but not ideal

The pilots were late and it made us 1 hour late. The meat was tough and bok choy was also tough.

Stuck on tarmac for two hours plus a 5.5 hour flight. Rude flight attendant. And no meals, not even for purchase!

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

The best airline I have ever travel , really good customer service, attention and service !!

United sent me a mileage plus number last year but that number is invalid so I can’t use it to check into flights or collect mileage. There is human to speak about the problem, only computers who keep asking me if I am using the correct email. It’s so frustrating and I cannot resolve it.

Not a great experience. We paid for the upgrade for premium economy seats and seated ourselves in very comfortable seats. Someone came along with the same seat on their boarding pass. The aircraft had been changed and as a result we were booted out and sent further back to small uncomfortable seats. After complaining we were moved to emergency row seats, which gave us more leg room but the seats don’t recline. For people in our 70’s we found having to sit upright from California to NJ very uncomfortable. Not sure why they chose to move senior citizens instead of the two people that were allowed to take the more comfortable seats. Not happy.

Everything was great. Only thing that could’ve made it better was buy on board options for hot food, but the snacks were decent. The flight attendants were great. I had no complaints. I was able to make it to my destination safely

Boarded plane and then delayed 1.5 hours while on the plane

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

Really good 😊 the woman at the gate entrance was a little rude checking in our carry-on but i dont think she worked for the airline, she worked for the airport at sacramento, other than that amazing.

No paper towels in bathroom. Aisle seat difficult to get out of Other than those, excellent service

Both flights are delayed so I rate the whole experience as mediocre.

Bad experience boarding and flight got delayed didn’t make it to my next flight

The food on the trip Toronto to Athens could be better: the chicken didn’t taste good.

Before final boarding, my husband and I — both seniors — were told that we could not bring our carry-on bags with us due to being in Zone 6. The staff took our bags with little explanation, stating it was policy. While we understand boarding procedures may vary by zone, the way we were spoken to was unnecessarily rude and dismissive. We felt disrespected and singled out, and the interaction left us deeply uncomfortable. As seniors, we expect to be treated with courtesy and dignity, especially during travel when accommodations and communication matter most. We hope you will look into this matter and ensure better training for staff in handling such situations with more empathy and professionalism.

Easy boarding and comfortable seating were plusses. Enjoyed the experience and good service from the captain and crew. Many thanks...!

Somehow, my booking was under my preferred name instead of my legal name so they almost didn’t let me board the plane at LAX. This problem should have been notified to me when I was still in Toronto.

Poor air traffic controller staffing led to a 50%reduction on flights so we got to wait 4 hrs for our flight! Very disorganized at the gate Poor communication with customers

No Charging ports for personal electronics, which were required to use wifi entertainment.

They are a great airline, and i enjoying flying with them. However my experience with booking through Kayak was a horrible experience. With all the restrictions and glitches of website. My entire bookings by kayak was wrong. And there was no possible way of fixing anything with them, because they hand over responsibility to the airline after purchase is made. Will not be booking through Kayak again and will inform my family and friends not to as well.
