On time departure and arrival. Had to be the oldest plane in the SWA fleet but it got me where I needed to be.

On time departure and arrival. Had to be the oldest plane in the SWA fleet but it got me where I needed to be.

the flight was significantly delayed. Not much was done by the airline to compensate passengers

Boarding now takes twice as long since going with assigned seats.

Horrible communication from Southwest. No accountability. Flight was delayed for 4 hours and TSA closed in the interim. We were not allowed to our gate. Southwest knew this information and did not relay to their customers to arrive to the airport earlier.

had to check bag at gate when there was still overhead bin space. As usual the WIFI didn't really work.

Flight was delayed, full flight and I had to change gates. Southwest flights are always late later in the day.

there were two flight attendants that were up front...that were the best! They get KUDOs for making my trip only fantastic. Tell them Jeff said that!

Was fine, delayed and feels like southwest is always late

Seats were very comfortable. They tilted back. Drinks and snacks were free and served 3 times. Attendants were awesome.

Couldn't connect to the internet and movies. Needed help.

Frontier didn’t give us enough notice that our flight had been delayed. I was just entering the airport when I received the notice, less than 2hrs before my scheduled flight. They delayed it 1hr 22min because another jet left late out of Vegas. Frontier needs better communication with customers because I could have eaten at home and had someone drive me instead of paying for an Uber.

Frontier is good until they cancel your flight. Way too many cancellations.

The seats are tiny and they don’t recline. The planes are dirty and very small. You have to pay for carry on and even the personal item that you’re allowed is smaller than with other airlines. Flights are usually delayed and there’s no screens or any amenities or entertainment.

The staff at the check in counter was so rude. Made you feel Incompetent

This is my second time flying with Frontier. My current experience was very favorable. The staff from the gate to the plane was friendly, warm and professional. The food options lacked in my opinion. This area needs some attention in my opinion.

Boarding in Orlando was not good. Giant mob at the gate, should have been lines.

The ticketing agents were rude but then we had a great gate agent very nice we had to ride a buss out to where the plane was parked but it was in some back corner of the airport when we got to the plane the captain who was great btw was cleaning the plane because the same rude ticketing agent told them they we not contracted to vacuum the plane. The ride to las Vegas was fine We had a connecting flight to Dallas. The flight was fine but when we arrived in Dallas everyone who flew on any frontier airlines the picked up bags from baggage claim D15 had to wait over a hour for their bags to start we arrived at 11:30pm ish to the gate we didn't leave the baggage clamed till 12:50 am very not happy and i used to fly frontier 4 times a week for work in Denver i will not be using them again

I missed a flight because of a delay. I had to buy a new ticket through Southwest.

My flight was delayed by two hours which made it so that I would miss my layover flight. I stood in line for customer service for over an hour and when I reached the agent she told me to scan a QR code and it'll give me options. I wasn't offered any help, guidance or compensation, only told that I have options but that I had to figure it all out myself. I was refunded part of the trip and had to buy an expensive same day ticket from another airline in order to get home. I will never fly Frontier again.

Crew was excellent. Plane was small cramped Airbus A320. Seats were narrow.
