It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.

A 630departure flight Delayed 6hours! They changed my gate, I moved to the new gate. Had our flight on the screen for 12noon departure. I go get above to eat, check screen again and the flight was gone, no notice no announcement, nothing!! They sent my bag on the flight I wasn’t on, got it back to me 3days later. Thank goodness they did refund my money but I will NEVER fly them again.

Due to weather, my flight was delayed, further delayed, then canceled. I eventually got through to a support person who helped me find a different route out of MSP, but to get to DIA, they didn't want to, but eventually did help with the connection ticket purchase. But even this replacement flight was delayed time and time again, and I would have missed my connecting flights and I didn't want to get stuck in a layover city, so after 12 hours at the airport with two young boys who were very tired, we just cancelled our plans and spent the week at home, instead of Nana's.

The third party booking with cheapflightsfares was awful. Kayak should NOT partner with them. They sold me a bundle including seat selection and carry-on, but did not book the carry-ons with Frontier, so I’m out of pocket for $414 more while I await resolution.

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.
