The return flight was soooooo much colder than the departure flight to Connecticut! I appreciated the layover because I didn't have to change planes. The staff and the service were the best! Everyone was so professional and accommodating. Having internet was great, but for the movies the flight offers through the app could be updated. THANKS EVERYONE! I fly BREEZE every opportunity I can get.

The flight was comfortable with the usual slight turbulence. Macadamia Nuts would be great snacks to purchase in flight.

This is one of the worst trips that I have ever had. Ending up with an overnight delay. I’m not happy with the fact that they did not provide and set up the arrangement needed for lodging that we had to do it on our own. I also feel there should’ve been Compensation for food.

Had to approach landing twice which caused concern but probably due to weather

This was my first time flying your airline and it was okay. The people were nice but I am not used to all the add ons and no movies or even water. But I knew it was going to be that way. I think I prefer paying for the extras to be more comfortable.

Plane did no snacks and had no wifi or entertainment although the flight was 4 hours long.

My original booking was a nonstop flight. It got changed to a flight with a 6vhour layover that became a 7+ hour lay over. I'll never fly this airline again after this roundtrip is over.

I was surprised at how wonderful it was. The aircraft was clean. The crew was warm and welcoming and as a result the passengers were friendly. One warning the only free thing was water. I kind of liked picking wet hat I was willing to pay for and what I was willing to skip.

The flight wasn’t big on frills, which is fine with me. I flew into Islip MacArthur Airport, which saved me from having to go through LaGuardia to visit friends on Long Island. It was inexpensive and super convenient!

Great experience! This was my first time flying with them and I could not have been happier.

Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.

Southwest is typically delayed, and it gets wearisome. It is no longer a discount airline and you get way less than you pay for when it comes to comfort and Ce.

We sat on the plane on the tarmac for 4 hours.

I'm not a fan of Southwest's model. I don't like the herding style of boarding.

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.

They canceled flight. Hard to believe there was even a plane incoming for us to get on

The worst. We never made our connection and they did absolutely nothing to help us at the airport.

Our flight was cancelled. They could do nothing to help us get another flight that was timely. Because the first leg was cancelled we were unable to get to our connection. We had to book on an entirely different airline for today. So we spent more money, lost a day of vacation and will never fly Frontier again, so the 'we are sorry, here is $100 credit' is a joke since we won't be flying on Frontier.

No way to get boarding pass on my phone. In order to print the bag ticket a boarding pass is needed. Asked the agent to print me one, they said they typically do not due this as its so much work. I showed the email confirmation and I asked how i could do it my self the agent replied he did not know as there was no link. The flight was delayed due to an attendant forgetting to come to work. On the flight no drinks were offered only for purchase meals.

Since you have to pay for overhead bags then they shouldn't be running out of space and asking individuals who paid to remove stuff from the overhead

Cancelled flight after I arrived at airport after 75 min drive and parking. Next flight was 4 days in the future. Had to scramble and buy a much more expensive flight on another carrier.

Book with frontier airlines with the mentality that they'll cancel your flight, kick you off and lose your luggage. Anything besides that is a win. Compare prices with other airlines (to include luggage) and if frontier is still worth it, book it but know all of their policies.

You get what you pay for nothing essentially but a hard uncomfortable seat that doesn’t recline and kids screaming all around you and chaotic boarding and limited check bag weight allowance when compared to other airlines

I never got to experience the flight because they delayed my first flight and I missed this one. Then Frontier didn't want to help me rebook a flight to get me to my final destination.
