Frontier Airlines

Frederick W. “Rick” Brown, a pilot for United Airlines, his wife Janice Brown, and Bob Schulman—both of whom had previously worked for the original Frontier Airlines (1950–1986)—founded Frontier Airlines. Boeing 737-200 jetliners were used to launch regular flights between Denver and four North Dakota cities on July 5, 1994. Frontier began serving destinations in New Mexico, Montana, North Dakota, Texas, Nevada, Nebraska, and Arizona in January 1995 after expanding its route network from Denver.

Frontier Airlines, headquartered in Denver, Colorado, operates over 100 A320 family aircraft and has the largest A320neo fleet in the Americas, serving approximately 120 destinations in the United States, Caribbean, Mexico, and Central America. The use of these aircraft, as well as Frontier’s seating configuration and weight-saving initiatives, have all contributed to the airline saving 43 percent more fuel than other U.S. airlines, making Frontier the most fuel-efficient U.S. airline.

Families are a priority for Frontier, which not only offers the most affordable rates but also, via its Discount Den travel club, waives the child fare for passengers under the age of 14 on select flights. With more than 140 new Airbus aircraft on order, Frontier will keep growing to fulfill its mission of offering inexpensive travel throughout the United States.

Frontier Check-in

To guarantee that you can check in and be at the gate by the cutoff times, arrive at least 2 hours before departure. The following deadlines must be met in order to print your boarding pass and have any baggage inspected:

Domestic Flights: 45 minutes prior to departure

International Flights: An hour prior to takeoff

No later than 30 minutes prior to departure, kindly arrive at the gate and be prepared to board.

Frontier Seat Selection

Seat assignments are not included in Frontier fares. Seat assignments can be purchased both during and after the booking process. If you already have a ticket, you can purchase a seat assignment online. Seat selection is an option. If you do not purchase a seat assignment, one will be assigned at random during check-in. However, your group may be split up.

Frontier Baggage Policy

Personal items are limited to 14" tall, 18" wide, and 8" long. Personal items must fit completely within the bag sizer's personal item portion.

The maximum dimensions and weight for carry-on luggage are 24" tall, 10" wide, and 16" long (including handles, wheels, and straps). Carry-on luggage can be stowed under the seat or in the overhead bin. Consider carrying large backpacks, compact duffel bags, and compact wheeled bags!

Checked bags must be no more than 62 linear inches long (length + width + depth) and no more than 40 pounds in weight. Bags that exceed these limits will be charged an additional fee for each overweight bag and a separate fee for each oversized bag, and bags weighing 100 pounds or more will not be accepted. Bags that are longer than 110 linear inches will not be accepted. Consider large duffel bags, suitcases, and sporting equipment.

Traveling with Kids

Infants can fly for free in an adult's lap on Frontier Airlines up until their second birthday if they are seven days old or younger.

A second personal item, such as a diaper bag, may be carried for free by an adult traveling with an infant on their lap. Children older than two years old are required to have their own ticket and seat. These kids can ride in harnesses or car seats that have FAA approval for added safety. During the flight, booster seats are permitted, but not during takeoff and landing.

Strollers are permitted, but they must be checked once you get to the gate. Free check-in will be provided for the stroller.

Traveling with Pets

Domesticated dogs, cats, rabbits, guinea pigs, hamsters, and small household birds are permitted on domestic flights within the United States for a one-way directional fee. Domesticated dogs and cats may only be transported to and from international destinations. Your pet must remain in its travel container at all times for safety reasons. Pets are not permitted to be checked as baggage.

The pet must be able to stand, turn around, and lie down in a natural position in the travel container. The carrier must also be able to fit beneath the seat in front of you. In addition to your pet's travel container, you are permitted to bring either a personal item OR a carry-on bag. A fee will be charged for the carry-on bag.

Service Animals

Only dogs that have been trained to do work or perform tasks for the benefit of a qualified individual with a disability will be accepted as service animals. This includes service animals for people with mental illnesses.
