Seats are still too crowded and uncomfortable on long flights like this cross country one.
Seats are still too crowded and uncomfortable on long flights like this cross country one.
Laney was very helpful. I am computer illiterate. She helped me obtain a boarding pass and preferred seat. She was warm, friendly, helpful, and smiled. I was impressed.
The actual flight I was rescheduled onto was from Seattle to Bozeman. The flight itself was fine, but due to delays/air traffic issues i spent the day hanging out at the Seattle airport and had to miss a day of work.
OUr pilot was very good and also a good landing in a very gusting Phoenix. Most important.
No non-alcoholic drinks available except water and small apple juice cans.
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
Flight crew and cabin crew were great. I had to rearrange flights because my original flight was 3hrs delayed for weather, the rub is the flight I moved to boarded on time then we sat at the gate for 2 hours because scheduling stole our first officer for another flight, TWICE. Then our actual FO was an hour delayed. To make it worse my original flight went from a 3 hour delay to departing 15min EARLY. Just poor scheduling operations all around.
Bring back peanuts Take our drink orders when were all seated, especially after you switch to assigned seating.
Staff was far less than helpful at all times. Departure and arrival times mean nothing to Southwest. Extremely disappointed, will never fly with them again, and I’ll be sure to share my experience with all.
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!
I wasn’t able to check in online at either website Hawaiian or Alaskan. I called Hawaiian to check in the night before and was put on hold for 1h 30 min with no customer service help. Gave up and hung up. When I went to ticketing counter couldn’t check in at computer. Went to counter and they let 6 people check in before me. By the time I was able to check in all the seats were gone and got the worst seat assignment back seat with no reclining chair and next to the bathroom. Had I been able to check in online for both flights I don’t think I would have gotten stuck with a bad seat assignment. When I asked Alaskan check in person why I wasn’t able to check in online he said he couldn’t help me or tell me because he didn’t know. Never have had suck bad experience with either Alaskan or Hawaiian when they were not merged together.
We boarded an hour and a half late because a coffee maker leaked in the plane. Then we had to wait for awhile to get off the plane because another plane was in our spot at the terminal. I had plans when I landed that I had to skip so it was pretty disappointing.
When I was not allowed by Alaska airlines to board due to time and difficulty pre-check the night before and kiosk did not work when I arrived at the airport and then finally told Alaska airlines is where I had to go. Not Hawaiian airlines that they had moved. That's when I was treated with the utmost disrespect by Alaska airlines agent that I was not allowed to board. And that might ticket to return was canceled and I hadn't even left yet when they gave me the option for the next flight to raise my flight price to $300 one way. I bought a $96 round trip ticket and they're trying to gouge me for $600 in addition and canceling my return flight.
Alaska airlines was great, Kayak not so great. I couldn’t get my boarding passes and I was last to board. Will not use Kayak again, ever!
Love that as soon as you get on you are seeing and hearing Hawaii. Was glad to hear that they are stressing safety over the pressure to arrive on time.
Despite two calls as well as a chat on the website, Alaska would not add my TSA number to my reservation. The flight was switched from Hawaiian to Alaska which caused them to mess this up in the first place
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
The flight was canceled and no option was given to get me to my destination even though there were 3 other flights going to Las Vegas later on that night. I will never fly on Spirit Airlines ever again. Terrible service!
I book a filght for me and my daughter from Miami home to Las Vegas and getting her checked in was awful the lady at the baggage check in was horrible!!! She was the rudest person I have ever encountered in my entire life!!!! My daughter dose not speak Spanish and so I was trying to translate for her but the woman would not let me so my daughter was 100 💯 confused because she could not understand what was going on or being said at all horrible absolutely horrible and rude extremely stressful worst experience ever!!!!!!! And then we were actually told by other air port staff not to complain because if we did sprint would make sure we miss our flight ✈️ that they do it all the time 😧
Not good. No updates regarding the flight status until after the fact on the delays and then a cancellation.
If kayak actually provided me this flight and didn’t just send me notifications about it
Worst Airplane ride I ever have taken... My purchased seat was changed without my consent
Surprising everything went well. Nice attendants and fast getting on and off the plane. Overall, was happy with the experience.
I was surprised by a mandatory bag charge when I checked in at the airport. "Carry-on" wasn't an option eventhough all that I had was a small pilot case. I paid $79 so my bag could fly with me.
Not efficient. Missed my connecting flight over improper operation of spirit crew.
I couldn't understand the crew when they announced it was a new plane and there was therefore no wifi, huh? Seriously lame for 2025!
My experience was very nice. However, my Spirit flight 409 from Las Vegas to Tampa… the gate Associate Tissa was extremely unprofessional and boarder line rude. While in line I found out that my Uncle died… in that moment Tisza asked if I would help in car of an emergency as I paid for an exit row seat. I stayed “I will”… Tissa didn’t hear then implied that I didn’t understand English, yelled that I needed to speak up and other things. Associates like that will cause Spirit airlines to lose customers.
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
