Airline reviews

Pros: "It arrived on time."
Cons: "The plane was filthy."

Pros: "Friendly staff, good seats."
Cons: "Baggage prices"

Cons: "The flight attendant who presented the pre-flight info was snarky, made inappropriate remarks that she thought were funny and was unprofessional. This totally undermined my confidence in the crew. I think they should present that they take our safely seriously. I am unlikely to use this airline again."

Pros: "The crew had a great attitude and was able to make us laugh despite the fact that we were leaving late."
Cons: "The plane was dirty- there was balled up gum wrappers, food wrappers, and bites of food on the airplane floor. To make maters worse the carpet was already stained in multiple spots. My tray table also was dirty with sticky soda that had spilled on a prior flight. I was quite disgusted by the condition of the plane."

Cons: "Problem with the bathrooms had to sit on plane over hour waiting to be fixed. No refreshments served. Couldn't pay for bag on line so had to pay at checkin ..... not fair!"

Cons: "Short-staffed, so short tempered workers.kiosks did not work. Nickled and dimed on everything. Like flying in prison. No light and a cold hard bench seat. Awful."

Pros: "The staff was surprisingly welcoming for a budget airline. Everything went very smoothely and both my flights on this round trip arrived early. Well done!"

Pros: "When we landed and exited the plane"
Cons: "Charging for carryines just ain't worth it. I'm not ever flying frontier or spirit. The extra cost for no hassle will be worth it."

Cons: "Look like frontier is always late"

Pros: "Attendants were friendly, plane was clean, and the experience was overall great."
Cons: "It would have been nice if the plane carried wifi or some kind of tv/music option for entertainment."

Pros: "Nothing."
Cons: "Everything."

Pros: "uh the "big front seat" was decent? fairly roomy and still cheap"

Cons: "Being charged for a carry on."

Cons: "Trip had over 8 hours of delays."

Cons: "No free drink or peanuts."

Pros: "Smooth ride, convenient boarding. Very short distances, they may be OK."
Cons: "Checked and carry-on luggage rules are complicated to navigate. There is a charge for seat allocation, etc. We weren't even offered water free-of-charge! I wouldn't consider flying again. Because when you add the cost of luggage, etc. Southwest is more attractive."

Pros: "nothing"
Cons: "the fact that i was delayed more than 5 hours on the departure and more than 1 hour on the way back. Why is there an option for entertainment when none is provided? Also you need to pay for the food"

Cons: "to expensive to cary on a bag."

Pros: "Middle seat was empty"
