Gate agents were informative and friendly… flight attendants were as well. Had a fun time chatting about their legacy AirTran experiences as a former fan of the airline that Southwest acquired.

Gate agents were informative and friendly… flight attendants were as well. Had a fun time chatting about their legacy AirTran experiences as a former fan of the airline that Southwest acquired.

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.

Purposely delayed the flight by 2 hours and 58 minutes so that they would not have to give me the FAA mandated refund for a delay of 3 hours. Offered flight credit instead. All that is offered on board is water and coffee, everything else costs money. They charge you for carry on and checked bags. Would not fly again.

nice flight. no frills but a 3 hour flight I caught up on my sleep. Stan O

First time flying Breeze, was very impressed. I will use Breeze again.

The flight was rescheduled and canceled. I had to go with another airline last minute to honor my school commitment. The reimbursement is a joke -$150 for a one way plane ticket.

The flight itself was A+ but boarding sucked. They boarded all passengers at once, and as a result I did not get to put my carryon in an overhead bin near me so I had to wait till near the end to deplane.

Really appreciate the great crew and pilot for keeping us informed about everything going on, updates, etc. It's so reassuring just to know (for example) why there might be a delay, etc. I'm very satisfied with the excellent service.

This was my first time flying Breeze. The plane was one of the nicer planes I have been on. The flight attendants were friendly and helpful. I will fly them again.

Well, Kayak should have communicated with Breeze that when I purchased the ticket, Kayak should have relayed that I had one carry on as part of my ticket purchase. So, KAYAK, tell the airlines!

Why do I need to spend $$$ to sit together as a family? It’s beyond frustrating, we were all sitting apart.

Easy boarding and great communication, smooth flight- all was great!

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

I rate it is good we had a 4-hour travel delay at one point but JetBlue gave out food vouchers and travel points credits for another flight so they try to make up for it

Did not enjoy this flight at all. All of my coworkers flew delta and I chose JetBlue because I really value how simple the WiFi and entertainment is and this flight I didn’t get either. Crew staff was unsympathetic to my system not working, everyone I asked for help with was extremely bothered by my request for help.

Little snafu at boarding. Staff communicated with gate poorly. Flight attendant was rude making disembark early. This was an older mint class. Needs an overhaul for sure. Food was good. The male flight attendant was really nice.

Like the space, did not like the snack options, there was no power outlet in seats, no entertainment, no flyfi.

In-flight staff was very helpful and excellent. However, the flight was delayed by 90 minutes. Also the boarding process should be expedited in case of delayed flights. This will help the passengers trying to make international connections.

They delayed our flight by 45 minutes and then re-updated the departure time back to normal schedule with no notification, email, or app update causing probably 40 people to miss the flight as they left without us.

The walk from baggage claim to the taxi is very difficult for older people I will never fly into JFK again. It is physically challenging

Overall fine but both ways for this trip was delayed.

Flight was delayed by almost 5 hours. Suitcase was not loaded despite the flight being near empty (my colleagues’ suitcases did reach JFK, unlike mine). Had to argue on phone to get JetBlue to deliver the case to my hotel. Never again

The flight overall was good but I believe giving back to the customers would be a plus. Not saying a big giving back but small is also acceptable like Wi-Fi (Free) or snacks(free). Just one would be good.

You get what you pay for with this airline. If you want comfort be ready to pay, the regular seats are like hard plastic bus seats and they don't recline, so again you get what you pay for, a cheap flight that is just alright. Which is what I wanted.

Stop nickel and diming passengers with different seat costs, paying for water, carry on luggage, etc.

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

Very easy with the app to board and staff skills

After waiting several minutes to be acknowledged by 3 employees on their phones, was told we had missed our flight because the doors were closed at that literal moment. Had they given any actual service or help while we were standing there we would have been on with time to spare. More than 10 people were turned away in this fashion claiming there was no way they could let us on the plane, even though it was still sitting connected to the terminal. After the desk agents let us know they didn't care about the situation we were forced to pay more than twice the price of our original tickets as no credits were given for the price of the "missed" flight. And the icing on the cake was after being treated poorly, fleeced for another few hundred dollars for new tickets? We waited on the next plane for 25 minutes passed the "doors closed" time, letting almost an extra dozen passengers on board. You're company has lazy, disinterested employees and your lack of any real help will ensure this was the first and last time we fly Frontier. Awful.

Flight was changed (according to Frontier, by Kayak) without my notification. And all flights were delayed by at least an hour and a half. Uncomfortable plane. Bad service. Will never fly Frontier again.

My experience with the phoenix airport was terrible, the personnel lay the ticket counter charged me for a carry on that fit in the carry on size box, and the two women I spoke with were terribly rude and not willing to help.,,, there was one lady “candy” on the flight crew that was amazing and is the only reason I stayed on the flight at all, because the other stewards helping people to get seated on the plane were terrible

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.

The plane was clean, the crew was friendly and helpful. It’s a low cost airline so there was no food, drinks or in flight entertainment but we didn’t expect any of these things. In the room for improvement department, they should install USB ports in seats to charge mobile devices.

The seats were extremely hard and uncomfortable, even for a budget airline.

The seats were extremely hard and uncomfortable. It was disappointing even for a budget airline.

Charging $74 for one checked bag is outrageous. I will never fly Frontier again.

Boarding was very well executed. Got my bag right away.
