Our agent was very helpful. Could have charged us the max rate for luggage, but she didn't. Arrived ahead of time on both flights. Knoxville made us sit on the runway for some time, even though bays were open.

Charging for one piece of luggage and carryon -Really!!! I had put on the website what luggage I had and when we got to the airport it wasn't in our info. We had to pay extra because it didn't come through on the website.

Frontier -- the Greyhound of the air! A la carte pricing, no tray table, no leg room, and you pay for everything -- including the right to not be placed in a middle seat. What a crock. The only reason I fly Frontier is that they have a direct fight from Knoxville to Denver. Otherwise, I would avoid them like the plague.

Frontier's customer service is god awful. The space they have in Phx sky harbor is one of the worst gates with awful service. We were removed from our flight without warning due to a mechanical problem on there end causing us to miss our next flight. So instead of rebooking us they just kicked us off and we were left to fend for ourselves over the telephone where we were told we can't be rebooked. They also didn't want to give us a refund but travel credit instead!!!! Yea right!!!! NEVER flying again with Frontier. THEY SUCK.

The direct flight was perfect.

The seats are about the least comfortable of any airline.

Mediocre 2.0

Nothing.

The four hour delay caused by a hydronic leak that couldn't be fixed on-site, the wait for a new plane, then sitting on the Tarmac for 20 minutes after being pushed away from the gate. Also, the check-in line was really long and slow because Frontier didn't have enough personnel to handle the job efficiently. The gate personnel need training in talking into the Mike, so that passengers can understand what they are saying.

At least they have Coke instead if forcing me to drink Pepsi...

Seats were uncomfortable. Was constantly touching a neighbor that I didn't know. Food was ridiculously over priced and not great. The plane I took after my layover was the same place. No biggie except that the reason I was able to identify that it was exactly the same plane is because I was one seat behind my first seat and I could see the chewed gum on the arm rest of the seat ahead. Get on the Puma plane and sit in F23. You will see it.

Super-friendly and helpful staff on our flight. (Our plane was "Ermi the Ermine," since Frontier's airplanes each are identified by a different animal or bird.)

Nice crew

I booked a LATAM flight for a 10.5 hour flight specifically because they have better in flight entertainment. I arrived at the airport and found it it was operated by AA. 10.5 hours with zero in flight entertainment. HORRIBLE EXPERIENCE.

No hassle of changing terminals in JFK, no bagagge claim, AA check-in-this time, was a "good luck"....Connection in Helsinki, very quik!

Finnair flight AY06 are old aircrafts. Every other in-seat monitor was out of order, flight attendants could not do much. That created mess for passengers, trying to move their seats to the ones with working monitors.....

The flight attendant was nice.

The boarding process was a nightmare there were 4 flights boarding at the same time from gate 57-61. People were coming in line from every direction and it took forever to walk a few feet to get my boarding pass scanned. Then about 1hr into flight it's was freezing in the front of the plane, I was in row 5 and the only solution given to several of those who inquired about it was to "take a walk to the back, it's warmer back there". We were dressed for the winter up front and people in the back were comfortable. It was ridiculous. Mind you this was a tiny plane 1 seat on the right and 2 on the left so not a lot of room to stand and move around.

No outlets to charge your phone, and the tv played the same movie over and over. The meals were also cheap. Didn't like any of them. Should have flown southwest or delta.

it got my mom from one place to another in less time than a car would

this flight was also delayed and you lost my mom's luggage and took 4 days until she finally retrieved it. How do you stay in business anyway with all the up charges and delayed flights and lost luggage? I will NEVER book flight with you again for myseld or my family and I will tell all my friend and their friends that if they want a miserable flying experience...then they should definitely fly with you. Shme on you for taking people money!! Hopefully a bigger airline will buy you out before you have to claim bankrupy
