7.6 Good
SFO-DEN
Pros:Everything was good except what I mention below. I would fly again, as your aircraft was clean, and the food/beverage packages had good options, I will just add additional bagage costs to the ticket price to make a determination of whether the flight is worth the price.
Cons:Paying for a carry-on. I would not have booked with frontier had I known I'd have to pay for the very small duffel I brought with me. I could have booked with Delta, had free beverages, and not paid for a carry-on, all for less than what turned out to be the total cost of this frontier flight. It should be clearly stated before booking that ANY bag brought with you would incure a fee. People would factor this into the purchase price and book accordingly.

DEN-SFO
Pros:The flight departed on time and arrived as scheduled.
Cons:I'm glad that I arrived safely because that is the one thing I can appreciate. The cheap fares equal the quality of the plane. Only 4 rows of 30 have reclining seats. It would be a stretch to say the seats are padded. The clientele is cheaper than the fare with lots of crying babes and impolite guests running to the door as the plane arrives to the gate.

DEN-LGA
Pros:Staff did a typical job, everyone was nice, nothing notable.
Cons:Frontier airlines is awful. With all the added fees, I could have just booked with Delta or another airline that at least offers their passengers water without charging for it. Or charging for my bag. What a joke. Not worth the "discount" at all and would never bother booking with them again.

Frontier contact information

Overview of Frontier

Focusing predominantly on domestic travel within the United States, Frontier flies to smaller regional locations as well as large cities. Controlling operations from a hub in Denver, the airline reaches more than 105 locations across the United States. Services are also available to international vacation destinations in Mexico, Jamaica, Puerto Rico, Canada, and the Dominican Republic.

Frontier operates as an ultra-low-cost carrier with competitive prices and direct single-leg trips. Fares are kept low by sacrificing luxuries, such as in-flight entertainment devices, while meals and drinks can be purchased as extras. It is a subsidiary of IndiGo Partners, which also controls JetSMART, Volaris, and Wizz Air. A codeshare agreement is held with carrier Volaris, expanding the possible connections between Mexico and the United States.

It is possible to sit in either Economy or Stretch (their version of Premium Economy). The chairs are not designed to recline, meaning the person in front of you won’t encroach on your space. Seats in the Stretch section have roughly an extra 5 in of legroom and a large pull-out tray that is ideal for working on a laptop.

Exclusively Airbus aircraft are chosen for the fleet, with Frontier preferring narrow-body jets like the A320 family. One of the most commonly flown models is the A320neo, which has tremendous fuel efficiency and can carry approximately 186 passengers. The planes have distinctive animals painted on the tails and are all unique images. Among the animals featured are rabbits, dolphins, bears, sea otters, and penguins. The names of the characters appear underneath the cockpit windows.
