Cons: "Could not ask for a better service!!"
Pros: "Alaska is the friendliest airline, throughout every touchpoint we have with them."
Cons: "Flight delayed. Delayed. Delayed. Seat changed without notice. Flight attendants were a bit rude."
Pros: "Um rude staff who couldn’t even be bothered to tell us where we would claim our bags, with ORD being a bit unclear for Alaska Airlines. Seriously, just communicate and be polite human beings."
Pros: "The crew, boarding process, baggage check in, everything really is just a breeze."
Cons: "Please refresh the seats a bit. I know space is limited and getting tighter all the time, I get that, but please improve the comfort of the seats. They're unbearable after 30 min."

Pros: "The boarding was very smooth"
Cons: "The crew didn’t look happy The coffee was cold didn’t have enough creamer and water!! The flight attendant looked really mad serving it"
Pros: "All the stewardess' and pilots were very friendly and even noticed that they were friendly to one another. Planes were clean, seats were comfortable. It was my first time flying at 54 years old and the stewardess' checked with me several times to see how I was doing and even the pilots spoke to me about my fear of flying prior to take off. All in all Alaska is great to take care of their passengers the way they did. They seemed to go the extra mile on both my flights."
Cons: "N/A"
Cons: "The snacks were good, but they should have offered some drink selections."
Pros: "Flight was good and crew were good. Nothing very outstanding but by no means a terrible flight."
Cons: "The in flight screens weren't working well."
Pros: "Everything was on time and ran smoothly. The seats have more room than most airlines. They were generous with drinks and snacks."
Pros: "Very engaging crew."
Cons: "Waiting 45 minutes, and 30 minutes after flight time for a few bags. They could have traveled on the next flight and arrived at almost the same time."
Pros: "It was all good glad the last leg of the trip was pleasant."
Pros: "The airplane seats and entertainment were 150% bettter than American"
Cons: "The check in area felt cramped, understaffed and like a 4th rate airline"
Pros: "Good variety and quality meals during the flight as well as a super array of entertainment"
Cons: "The seats lack cushion so a 7 hour flight gets quite painfully after a while"
Pros: "I was fortunately upgraded to 1st class. The flight attendant was adequate. However, did not live up to the level of service I have come to expect."
Cons: "See above"
Cons: "The unfortunate delay prevented me from attending my grandmother’s wake. Fewer delays would be helpful."
Cons: "On board entertainment was inop, making for a long (4) hours flight."
The employees at the check-in counter said my disabled wife and I were going to be separated even though we picked seating together when we bought our tickets. They told us my wife would be seated in row 2 and I would be in row 8, because we bought our tickets from a third party. Fortunately the flight crew said: "No, you two need to be together, we'll fix this." Then they seated us together. We are 75 years old and flying is a challenge for us, so we appreciate all the help we can get. Your flight crew was awesome with us, and with the children on our flight as well. Thank You Allegent Air Lines! 🙂
Plane had mechanic problem that was never explained. Had to bring a plane from another airport. Six hour delay. No apology for the delay. Not even an acknowledgment.
Pros: "The direct flight is amazing. The status updates were great. The crew was super friendly."
Cons: "Not much, it was great. No more masks for vaccinated people would be awesome."
Pros: "All around terrible Airline. Canceled our flight at the last minute, all the while telling us they had it under control and were going to fly. Made us sleep in the airport all night, re check in, bags and all at 4 AM, without any compensation at all. Don't fly this Airline."
Cons: "All around terrible Airline. Canceled our flight at the last minute, all the while telling us they had it under control and were going to fly. Made us sleep in the airport all night, re check in, bags and all at 4 AM, without any compensation at all. Don't fly this Airline."
Cons: "I don't think any sanitization took place in between the people who rushed off the plane and when my flight boarded."
Pros: "I love that they fly out of smaller airports. I feel like the crew is kind and helpful."
Cons: "The seats are not very comfortable but luckily most of the flights are not too long."
Pros: "Crew was good but baggage claim took forever. The seating was not well arranged. The seats were very uncomfortable. The weight limit of the bags were unreasonable"
Cons: "Better seats could be better"
Cons: "Great price. Wonderful flight. Seats are so close knees touched the whole flight."
Cons: "Covid travel. Had us board an hour before take off and the back half of the plane was 100% full. Every seat including middle seats. 15 min before take off they allowed passengers to take empty seats and spread out."
Pros: "Allegiant does a great job of turning flights and getting you out on time in general. The crew is friendly and helpful."
Cons: "flight was packed and attendants were nice but gone are the days of comfortable travel in coach"
Cons: "Our flight was cancelled til 24 hours later. And then delayed two more times before we were able to fly out. Very frustrating experience"
Cons: "Not being an hour late. Someone to manage social distancing at gates. What a mess. Flight was easy tho."
Pros: "Bags are no where to be found after landing 25 minutes ago"
Cons: "Really rude check in with bags and flight attendants are rude too. Haven’t flown American Airlines in years and will try to avoid them again"
Cons: "Nothing--everything was great--perhaps the best service I've ever received."
Pros: "Nothing"
Cons: "Overall a horrible experience. Would never choose American Airlines given other choices. This was the second time this year I was held at an airport over 24 hrs due to plane maintenance."
Pros: "Seats seem to get smaller but overall a good experience"
Cons: "Seat room"
Cons: "The crew was outstanding and the aircraft was new and comfy"
Cons: "The airport experience was horrible. American Airlines did not have enough personnel on duty to process all the waiting passengers."
Cons: "Ohare baggage claim. I was first class and my bag came out last"
Pros: "the front desk at united was awful. The flight crew were very efficient. Terminal 2 is great at Sky Harbor."
Cons: "nicely done, kayak!!"
Pros: "The crew was friendly but because of 5 flight delays we missed our connections in Amsterdam and got stuck in Houston for the night."
Cons: "The crew was friendly but because of 5 flight delays we missed our connection to Amsterdam and got stuck in Houston for the night. Because of this we were forced to pay for a hotel in Houston. I believe that we should have received some type of voucher for the huge inconvenience and waste of money"
Cons: "Boarding before scheduled time was not pre announced, seats lack legroom, unlikely to choose United again"
Pros: "Seats were very comfortable in first class. Very happy with that experience for short haul flight. Enjoyed the service. Flight attendant checked on me multiple times and offered beverages."
Cons: "Snack/food choices."
Pros: "Safe landing, that’s all that matters."
Cons: "The entrances by groups. I get it, I just don’t care for it."
Pros: "Nice crew."
Cons: "So cramped it’s not even funny anymore. I’m 6 foot and average build. The seats are so narrow, thin, and with such little legroom, I just can’t imagine who can comfortably fit in a United economy seat anymore."
Cons: "after boarding, we sat on at the gate for nearly 30 minutes without any explanation given. When announcements were made the person's language skills were greatly lacking - we could not understand anything that was said. there is no food, drink, or entertainment... unless you consider the man behind me playing with is cat .... and yes I'm very allergic :( landing crew didn't know where our luggage was to be returned (bottom of the gate or top of the gate). After a considerable time, we were told all luggage was delivered to the baggage concourse."
Cons: "United has a 2 hour delay for mechanical issue. We almost missed our connection to Zurich. Our bags did not make it and we are still waiting for our luggage"
Pros: "The flight attendant refilled my ginger ale without me needing to ask. Smooth flight until we approached Denver. Always hit turbulence when landing in Denver."
