Pros: "Friendly crew. Roomy Sears."
Cons: "WiFi did not work, no food offerings (even for purchase) on a 6+hr flight, and there were no headphones to watch movies."
Pros: "The plane was super empty so everyone had their own row to themselves"
Cons: "The flight was bumpy but I think the pilot did all he could"
Pros: "Our flight was delayed due to weather. Every effort was made and ultimately the wait was minimal as compared to the original estimate. The attendant at gate 4e was so courteous and kept us constantly informed. Staff are always courteous, friendly and work very hard to help. Jet Blue is definitely my preference when flying."
Pros: "Comfortable,spacious seats. Direct TV. The flight attendants were efficient and polite."
Cons: "Everything was fine. No complaints."
Pros: "The crew was friendly and accommodating"
Cons: "Boarding took longer than anticipated and limitations of overhead compartment space delayed departure as several passengers had to surrender their luggage to gate check."
Pros: "Really enjoyed the leg room as well as the snack options on the flight!"
Pros: "An overall very pleasant flight with great snack and beverage choices!"
Cons: "On past PHL to BOS flights beverage options were limited but there were a few choices. Today, only water was offered. Also, the new service cart wasn’t used"
Pros: "The crew were so great, seats were bigger than I’m used to, and the movie selection was great. captain got us boarded and was able to take off earlier than expected. Arrived a half hour early."
Pros: "Extra legroom where definitely worth it!! Crew was pleasant and professional."
Cons: "Waiting area in Phillie airport needed some live. That may not be Frontier’s responsibility..."
Pros: "The crew called out beautiful sights as we passed over them. The flight attendants were sweet"

Cons: "Not much leg room but expected with budget airlines"
Pros: "Was direct and easy. No issues with boarding or flight"
Cons: "Cramped"
Pros: "The crew more than adequate. Very nice."
Cons: "The two hour delay caused by no one noticing that the tires needed to be changed which, according to your own pilot was listed as part of the needed ground Maintenance. Boarding the plane before they were changed. De-boarding the plane to change the tires. The one and a half hour wait at the gate for your company to approve the plane for flight. This was not a good experience and I do not want to fly frontier again as a result."
Pros: "Nothing"
Cons: "I will never fly Frontier airlines again. No matter how inexpensive the tickets are, it is not worth the aggravation. Agents were rude. Flight horribly delayed. Plan ride was uncomfortable. I lost my car rental because they close at 5:30pm. When there own employees say there flights are always delayed that alone said it all."
Pros: "Great customer service checkin they were very kind and patient"
Cons: "the seats are not very big"
Pros: "I arrived safely. The crew was very friendly and helped to. All my husband who was scared as this was his first time flying."
Cons: "The agent who checked me in was extremely unprofessional. I felt like she was envious that I was going on a vacation and she had to work. She tried to make my experience a living hell. I personally think she should be fired. She does not enjoy what she is doing. She joyfully told me that it costs $40 to carry my luggage and after I informed her that I saw it online for less she informed me that I should have bought it online. She then stuck me all the way in the last row of the plane. I am 5'9". My husband is 6'2" and over 300 pounds. Those seats have the least leg room. It was pure torture. The flight crew in the back help my poor husband by using humor to help him."
Pros: "No service issues. Our seats were arranged so the family was together for no charge. We were given a bottle of water to mix baby formula for no charge."
Cons: "Hard seats"
Pros: "Wide aisle"
Cons: "Pilot forgot paper work and added 1 hour to our flight"
Pros: "Quick boarding, smooth ride"
Cons: "No entertainment or food or drink service on a 6 hour flight"

Pros: "Everything!!! Super impressed!"
Cons: "That I had to leave the amazing experience and go on vacation. :("
Pros: "No way to contact wheelchair assistance when being dropped of to begin flight. Waited 30 minuted for a wheelchair. Had to ask Amer.Air agent for help. Other airlines are far more attentive. Seats need 2 more inches, felt squished. Very costly baggage policy, charge for carry- ons."
