Good staff. Comfortable seats. Had to check my bag because the flight was too full.

The flight was extremely smooth, and so was the landing. Great piloting.

I’ve been flying Alaska Airlines for over 30 years & The boarding personnel letting us in the plane were the rudest I’ve ever experienced. Seemed the plane was over booked & they took THEIR mishap out on my son in law… Treated HIM like absolute garbage to the point our family will not fly Alaska after our trips are complete this year. Sad. We loved Alaska until that experience. I hope others never see the same behavior

seats good, foot space comfortable not good, waiting on tormack at Las Vegas

OK for the price paid but nothing as far as value.

Extremely poor, 1st time this has happened though. Traveling during the holidays, didn’t receive an update that our flight was delayed 3hrs. Lost our place in Airport Spot Saver to go through crazy long line at TSA, gate change and then another hour delay (makes it 4hr delay for a 2 hr flight to Las Vegas), stayed on tarmac for almost 25mins after landing. So 6.5hrs from Seattle to LAs Vegas. Could have went to Cancun instead.

Very late. Snack pretzels have no flavor. Soda options sink. Only one sugar free option and that with caffeine, bad for health

The ticket online purchasing, ticket staff, boarding staff, flight crew, etc. were all kind, courteous, and helpful. Only problem was the turbulence on landing. Out of your control though. Thanks.

Flight time was changed, leaving 2 hours earlier than time I selected without warning. When arriving at the gate flight time again changed. No in flight entertainment available.

The seat selection felt a little chaotic, but it might have been my inability to get an online selection.

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.

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.

Although an hour and a half early was told by staff at check in they had overbooked and could not check us in for the flight.

I’ve never traveled on Frontier before. If you want basic, no frills, friendly service at great prices then give them a fly!
