Good experience, although it was a little cramped being a tall person. Otherwise everything went smoothly and professionally though

Big delay of over 7 hours on next leg of trip with Alaska. Would have been nice to have food or something
Horrible! No blanket or pillow available! We had bulkhead seats but the seats were worn out and no cushion old. No meal or even a sandwich for our 5 hour flight just a little bag of pretzels. Crabby attendant female with long brown hair. We will not book Alaska Airlines again
All good. Great food and entertainment when there isn’t any on a one hour flight
The flight was delayed over two and a half hours thus causing me to miss my best friend’s funeral. All because the flight crew had to get more rest. That was the reason stated. I understand however very unfortunate. Glad everyone is well rested and resting in peace.
All good except both the outbound and return flights were delayed about 1 1/2 hrs.
Not great. My flight was canceled due to a mechanical problem and I could not get rebooked for the same day. I needed to get to my destination yesterday, not today. I was able to book with another airline but it was a layover and ultimately a 1 hour flight took me 12 hours. Normally I like Alaska much more than Southwest, but Southwest came through with a not terrible price for same day.
The plane was late arriving. The Alaska people did a great job of turning it around quickly and getting us off. We took off about 35 minutes after it reached the gate.
I liked the flight attendant named Tyler. He was charismatic and genuine. I like the pilot in my second flight, he was considerate to everyone’s feelings. I liked the people I sat beside. I like the plane size. I like Alaska airlines
I appreciate the priority for safety. I did not enjoy how the delays were handled.
First time traveling on Southwest since bag fees were implemented. Usual good service. Just more expensive now.
It was a perfect flight in all aspects! Both legs!
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.
Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.
Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.
Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.
Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.
Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.
Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.
I used to fly SWA all the time. I know the crew has their little acts that are often fun, and entertaining. On this flight one of the crew was just not nice. Very surprising.
I was put in a middle seat with the people on either side of me kept passing their grandchild over me and talking back and forth while I was trying to rest or watch a movie. So inconsiderate and totally disturbing. I asked if they would sit next to each other to alleviate the constant impeding my comfort but they refused.
Late boarding, full flight. Absolutely no food and barely a bag of pretzels. No video screens and slim pickings of movies. No live tv and poor selection of shows.
Pre-Flight check-in Staff did a terrific job correcting a seat mis-assignment problem after I checked in the night before my flight. They really stepped up to make my flight home a joy. It was also my birthday, so the flight crew made me feel special a little treat.
Our flight delayed 2 hours, no WiFi in flight and the snack option isn’t great either.
I was unable to get a check im and get a boarding pass. I tried at the desk of the flight operator Alaska, was told to go to Hawaiian and almost had to go back to Alaskan. In the end inwas told to go thru security and directly to the gate without checking in. It would have been more helpful to have the details rather than walking all over the terminals trying to check in.
Good except that I couldn’t change seat and made me wait untill I checked in
Traveling with my 90 year old mother, the boarding process was great, the gate crew was very helpful and friendly. One of the flight attendants was kind enough to assist her to and from the restroom mid-flight and cater to any requests she had. I wish I flew Hawaiian Airlines more often, it was a great trip!
We were delayed at the SD gate for close to an hour before we were allowed to depart for SJ. Reason given was inadequate ground crew to move the plane from the gate.
Thanks to the supervisor Jose my pregnant wife and our family will not miss a very important ultrasound tomorrow. What he did was simply heroic. He needs to be promoted and praised. Please tell him our family appreciates him so so much!
Your crew shortage delayed departure by an hour resulting in us missing an event we had scheduled for that afternoon outside of Fresno.
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
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.
Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.
Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.
The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.
While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.
get E+, a must for 5 hours flight if you are tall
Compared with other carriers business class for an overnight was not worth the extra expense.
Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)
Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.
The crew was mostly okay. The flight attendant who answered our questions was curt and unhelpful unfortunately. He seemed upset and I understand having off days.
Very bad! No good service delayed my second connection flight
They canceled flight. Hard to believe there was even a plane incoming for us to get on
Plane was down graded and I lost my uncharged exit row with more leg room. No mention or offer of refund from podium. Flight attendant was nice to explain this happens often and that I could request a refund via online form submission. I did this and have heard nothing back.
Horrendous. I do not recommend Frontier. The passengers lack manners and decency, and the flight attendants lack professionalism. If I wasn’t in a bind to fly with 48 hours notice for a job interview, I would not have selected a flight with Frontier and I never plan to fly with them in the future.
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.
Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.
Everything went as planned. Crew was great. Seats were still not that comfortable.
No frills for sure. No gate announcements about flight delay, not even water to drink on the flight.
I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.
