Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.

Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.

Wi Fi was horrible kept cutting out the whole time and too expensive

I really like open seating. I hate that I've heard this is going away. This is one of the unique things that makes Southwest my goto choice.

Boarding was a little late, but made up for it. It was quick to taxi to the runway, since it's a smallish airport.

Excellent! Only question is how we check in at exactly 24 hours in advance and end up at the end of the B boarding group

Multiple delays and gate changes. Arrived at final destination 6 hours late. All rental cars had been taken.

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.

It was 2 hours 45 minutes late, for no apparently clear reason.

I recently flew Southwest from San Jose to Honolulu. I was very impressed with the flight crew, especially the flight attendant in charge of the front of the plane. She came through the aisle at least five times for drinks and water, and two times for snacks. I have not seen such service since I flew first class. Also, for the first time, they gave us the correct baggage claim number, and the luggage came out quickly. I can't wait for Southwest to have assigned seating! I absolutely hate the Cattle Call boarding procedure and the mad dash to get seats and overhead bins. However, the boarding was efficient.

Crew was great flight was great baggage claim was a failure. It took over 1 hour for bags to arrive. Poor communication poor effort when I spoke to the supervisor about the delay

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Flight left early and arrived early. the whole trip was excellent.

Seats were really tight and the seat belts did not give enough slack.

I like in St George and prefer to fly out of CDC than SGU. Hopefully, they will continue the flights out of Cedar

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

Newer plane, relatively easy boarding, not a full flight and was told that we could not be moved up because of weight and balance issues. Otherwise, a very good experience.

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

Maybe add a seat trade app for flyers that didn’t get seats together

It’s been awhile since I have traveled on United. I, along with my family who were on the flight noted how smoothly everything went . Boarding, flight crew and service was excellent.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence.

There's just no way to sit fully upright and comfortably in these seats. There needs to be 2 more inches of room, and that's not something that only one person on the flight needs - the whole flight needs 2 more inches of room. If that means you sell 6 less seats, so be it. It's too close for anyone. Forcing people to pay for "premium" economy just to get "barely enough space to breathe" isn't really an answer to that.

The crew were very nice. The Chocolate is good and v there’s no entertainment. Thanks

The crew were very nice. I would have appreciated a pillow for comfort. I had a special meal that was sloppy, but the salad was great. Thanks

I liked all the informational texts. I always knew where to go and when .

Liked the hospitality . The ight took us 6 hrs to get from fort myers to ewr.

Oh my gosh, I loved my experience with United! they made me want to travel more often.

Boarding was smooth and on time. Flight itself was smooth (aside from some turbulence) and no glitches. On the downside, Spirit's no-frills service was as expected (no food or drink, cramped seating, extra cost for carry-ons, etc.), the announcements were nearly incomprehensible, and the constant niggling offers of upgrades and other services for sale (wifi, sandwiches, etc.) is annoying. Overall, a pleasant and uneventful experience - definitely worth the price.

Lower cost is the reason to fly Spirit. Should give free baggage with credit card.

From gate to flight crew... All Spirit employees were great! Everyone was kind and helpful. Ride was almost smooth... A few bumps... But no problems. Seats were tight and uncomfortable. Our biggest issue was no free drinks. I can understand paying for adult beverages and can understand no snacks on a 3 hour flight... But no drinks???? I had to pay $4 for an apple juice for my son. That's not right. You should probably reconsider that.

- flight attendants not very friendly. - Paid for WiFi and plane didn’t have it working , never got a refund.

Great! First time flying with Spirit and I definitely loved it!

Not efficient. Missed my connecting flight over improper operation of spirit crew.

Very difficult. Flew out on Dec 24th and it was a mess. They know it is going to be the busiest time of the year and they had no organization. Finally they called for people going on certiam flights so they could get them thru thw line then we had to rush to our gate to get in li e to board.We missed our flight do to being stuck at the border of Mexico. They would not work with us to make an affordable price so we had to wait a day with no where to go and pay 280 more for our flights. I would think that a complimentary drink would be nice. But we had to pay 4.49 for a coke. Not an overall good experience

Better service, stop treating people like cattle, have REAL FOOD for the price of the ticket. YOU ARE IN BANKRUPTCY, WAKE UP!!! ... DO BETTER, PLAN BETTER, GIVE COMFORT AND CARE TO PASSENGERS ... EARN RESPECT AND ADMIRATION, YOU'LL BE REWARDED BY THE PUBLIC.

It was good. All snacks/ drinks must be paid during flight. Bring cash with you.

The plane had to wait an hour before docking, then another 1.5 hrs to get our luggage. Bad experience.
