4.0 Mediocre
SEA-DEN
Seats were new and comfortable. Staff was fine. Missed my connection due to weather -which wasn’t their fault- but got no help at all. Gate staff sent me to customer service, which was and stayed unstaffed. Sign with QR code directed me to call or chat. Chat was useless. Call was returned after an hour. No itinerary offered by Frontier could get me home in less than 30 hours. Rebooked with another airline and got a partial refund that came to about 10 percent of what I paid to get home.

Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.

6.0 Okay
MBJ-ATL
Worst boarding experience. No zone boarding announcements.
J
2.0 Poor
PHL-ATL
sluggish boarding and arrival procedures, fake nice flight attendants, and lots of delays.
D
2.0 Poor
ATL-LGA
Disaster. They lied every step of the way. We ended up being delayed due to crew and then allegedly abandoned the flight because of a curfew at LGA. No rebooking to LGA at any reasonable time. No hotel. No meal vouchers. Had to sleep in the airport and fly to Newark instead. Will never fly Frontier again.
J
8.0 Very good
ISP-MYR
Direct flight was important. Seats are very narrow.
V
2.0 Poor
DEN-DCA
Extremely delayed flight, malfunctioning speaker, disinterested crew
