OUr pilot was very good and also a good landing in a very gusting Phoenix. Most important.
OUr pilot was very good and also a good landing in a very gusting Phoenix. Most important.
It was alright other than the changes in the Alaska Lounge. That and the migraine I had were disappointing. Other then that everything went well.
It was a short flight so no refreshments or entertainment which was fine.
Flying in both directions across country the gate designated on my boarding pass was wrong. From w to e across the country the passenger next to me coughed the entire way.
Although both planes (flights) had mechanical issue delaying both of my flights, the crew members handled everything with ease. Both flights had the smoothest take off and landing. I opted to upgrade my seat to first class and really lucked out getting the seat at the very front of the plane. Awesome treat to myself. I really enjoyed my flight.
The staff from check-in counter to the flight crew were great. Flight was right on schedule. 10/10
Changed flight from San Fran to Seattle Then with a Delayed takeoff barely made my connection Waited over an hour for luggage 😜
It was good. There was a mistake made in Seattle. Somehow we were bumped out of our seats as if we weren't on the flight anymore. The woman at the gate caught it and announced our name to come up and she fixed it.
I wouldn’t fly with Alaska again if you paid me.
Our flight experience started at the check in kiosk. Jennifer Polete smf 498304 greeted us and assisted us with our tags and check in guidance. She was so pleasant, helpful and friendly. This was the start of my experience with American Airlines and it made such a wonderful impression. The staff on the airplane were also kind, courteous, and attentive. I would definitely fly American Airlines again
It is southwest seat was ok. Not the most comfortable seat
I’ve always loved Southwest. No issues at all. I was flying standby and the gate agent was extremely friendly and helpful. Boarding was smooth and I was able to get a window seat in the emergency exit row. Crew was fantastic! They were very professional and accommodating. We had to divert from our destination due to weather but the flight crew kept everyone at ease and informed us of all pertinent information. Excellent flight
The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.
Plz don't take away free bags and free seating
The seats were a bit cramped and worn, but otherwise okay.
I would have liked to arrive on time - not 5 hours late!
After a 3 hour layover in Denver my flight was delayed over 5 hours! No explanation; no assistance; no offer to provide compensation; no one at Southwest was willing to offer any assistance. 8 hours in the Denver airport - ridiculous!
It was a perfect flight in all aspects! Both legs!
Only one drink pass through the cabin for a 4 hour flight. Quite rough and bumpy landing.
Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.
The departure gate was changed from C1 to B18 but it was never announced at the C1 gate nor did I receive any email or text message or phone call about the gate change. I was in a window seat. In the other two seats next to me were Mr. Rotund and Ms. Rotunda, a youngish couple. Just the two of them should have booked three seats. I was smashed up against the wall and window for five hours. Overall, I'd say my flight sucked. Wouldn't you?
I couldn't get checked in 24 hours before either leg of my flight. I tried both my Alaska and Hawaiian codes on both apps.
We moved from the international terminal to a new location. I think there are still some bugs to work out . We didn’t receive check in notification and had to scramble to find it but i think it will work out
I'm was impressed with their service. Everything was great
All in All a great experience. Cost of luggage sucks … first time I ever had to pay for luggage. Otherwise the check in counter was awesome, the gate clerks were great and the Stewards & Esses were the best.
As my daughter was boarding the flight they pulled her from the line and told her, after she had checked in and checked a bag, that she could not board the flight due to a fraud flag on the debit card used for the ticket purchase. The personnel would not allow me to speak to them, saying I had to take it up with customer service that was not present. They tried to get my daughter to purchase another ticket on the spot or get out. The customer service personnel were insistant that the personnel at the gate be on the phone which they would not allow. Would not accept payment from three different accounts and did not resolve the issue. Many conflicting reports about the source of the problem, the fraud department is uncontactable. The only good thing to come of it was checked bag arrived. Our family will not be using Hawaiian Airlines. Ever.
Great staffing. Terrible food. Please do cold sandwiches or salads. the "hot pickets" are terrible.
Love Hawaiian you can’t go wrong, still provides you good drinks and little snack at the end
No tv’s. Had to walk 45 minutes to connect to next flight. Couldn’t get dinner as a result. Ended up eating pretzels until I felt sick.
Not so good. The takeoff was aborted after reaching 100 knots due to a problem with the front tires. I do commend the pilot for a quick decision and preventing a potential disaster. We returned to the gate to put fresh tires on the front. Our flight was delayed for over 3 hours. The rest of the flight was okay. We were reimbursed by Hawaiian Airlines for only $50. Not too generous
Very friendly and efficient and smooth boarding. We were even way early arriving at my destination. Thank you.
The trip was very smooth and they provided great customer service
We kept being told that the flight was full and that all overhead compartments were full and therefore had to check in our hand luggage. We were some of the last people to board and noticed that there was still sufficient space in the overhead compartments. We were obliged to check in hand luggage when there was space and so had to wait at luggage retrieval which took a while to then noticed damage to our luggage - not a great experience!
The seats were crammed and the guy in front of me wouldn't stop reclining. If AA is cramming extra rows in, they need to take away the reclining in coach. My knees were smashed for 4 1/2 hours and I was very close to confronting the passenger in front of me.
What, first class and not even a cup of coffee before landing at 5 am in First Class? Really?
I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.
Customer service in first class does not exist on American Airlines
Flight was delayed due to a steering issue with plane. The delay caused me to miss the connecting flight. The delay caused me to spend an extra 21 hours in airports and flights to get to my destination. The plane issue obviously should have been found and fixed before we even boarded. Ridiculous.
Had to go get beer myself from attendants in the back of the aircraft
My flight back my reservations were list because they said I didn't pay my pet fee when I had a receipt
The reps working at the airport counter were dumber than a second coat of paint.
My costume jewelry was stolen out of my bag. Got to airport and my bag weighed 45 pounds- 5 pounds over cost me $100 Long lines in tier one. No entertainment No WiFi no free drinks or snacks
Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.
The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.
The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.
It was a short flight so no food or entertainment….
Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.
I’ve never traveled on Frontier before. If you want basic, no frills, friendly service at great prices then give them a fly!
Cancelled and declined to find alternatives Earlier flight is 2 days later Sent the cancellation notification very late, wish I knew earlier would have stayed to watch the Miami open final game Very disappointing service
The worst flight of my life. Never will I fly frontier again
