Kids Fly Free

Pre-Assigned Seats

When one or more of the passengers on a reservation are 13 years of age or younger, Frontier will guarantee adjacent seats for the child or children and an accompanying adult (over age 13) at no additional cost for all fare types subject to limited conditions specified below.

  • Child and accompanying adult are on the same reservation
  • Adjacent seats are available at the time of booking in the selected class of service
  • Adult either chooses seats for the entire reservation or skips seats for the entire reservation, and does not make changes to seat assignments once assigned to them
  • It is physically possible based on seat layout to seat the number of children traveling next to the accompanying adult(s).

Although Frontier will provide adjacent seats if available at the time of booking, Frontier might not provide seat assignments right away. Frontier will provide the customer the adjacent seating assignments no later than the day before scheduled departure of the flight.

Travel Tips

Don’t wing it - be prepared for your next family trip!
Check out our tips for family travel.

Traveling with Infants & Children

We want to help make your flight smooth and comfortable for your little ones. Find out some tips and resources to help make your trip as enjoyable as possible!

  • Bring a well-stocked carry-on bag, including diapers, wipes, bottles, snacks, a sippy cup, a book or two, and some quiet toys. If the child is old enough, download a couple of educational videos onto an iPad. This is a great attention-holder.
  • If you're bringing electronics for your kids, make sure they are charged and ready to go before your flight.
  • Comforting toys are great but keep other passengers in mind. Leave the noisy toys at home.
  • More leg room for you and extra space for toys is always a good thing on a flight with kids. Our stretch seating is a great way to get the space you need.
  • Babies and young children do not know how to clear their ears to reduce the pressure during takeoff and landing so unless your child is asleep, you will need to help them. We suggest a bottle for infants and gum or hard candy for older kids.  
  • We offer snacks, and beverages for sale on most flights (something to consider if the toys aren’t working or you run out of snacks)!
  • If you opt for packing your own snacks, bring along a Ziploc bag for wrappers and other garbage. This will come in handy throughout your flight with kids.

We know you want to make your child's trip easy and safe. There are some federal rules we need to follow to ensure the safety of infants and children.

  • Infants can travel for free, sitting on your lap from seven days old up to his/her second birthday. Please Note: A birth certificate may be requested for age verification purposes if the infants' age appears questionable.
  • Lap children may not sit in any seat that has an airbag seat belt installed which includes row 1 on most aircrafts.
  • Two adults with two lap children cannot sit in the same side of a row because there are only four oxygen masks per every three seats.
  • Only one child is allowed per adult lap. If you are traveling with two infants and you are the only adult in your party, you will need to purchase a ticket for them and have an approved car seat for the second child.
  • You may choose to purchase your little one his/her own seat and use an approved car seat on the plane, this is the safest way, if you can, we encourage you to do so. Our seat widths vary depending on the size of the aircraft. Minimum seat widths on the A319 and A320 are 17.4” and on our A321 minimum seat widths are 16.5”.
  • Car seats cannot be placed in emergency exit rows, in the rows directly in front of or behind emergency exit rows, or in the very first row. We also suggest placing car seats in window seats so they do not impede access to the aisle by other passengers.
  • If you're bringing a stroller, you can take it to the gate but it must be checked from there.
Pssst... Frontier Tip: Make sure your car seat is approved by the FAA. Look for the label on it that states, “This restraint device is approved for motor vehicle and aircraft use.” Use of the FAA-approved AMSafe Aviation C.A.R.E.S. child harness device is also allowed.
  • We fully support a woman’s right to breastfeed on our flights. Breast pumps are also welcome aboard.
  • We consider a breast pump to be a medical device. View the Frontier medical device policy under Sports Equipment and Special Items.

Unaccompanied Minors

Effective November 1, 2018, Frontier Airlines will no longer accept children traveling alone under the age of 15 yrs of age.  Any child under the age of 15 must be in the same reservation as an accompanying adult.

Traveling with Pets

Pets are like family. That’s why we’re committed to keeping your dogs, cats, hamsters, and more safe and sound on their trip. If you would like to take your critter on your next trip, there are few things you need to know first.

Need to add pets to your reservation during initial booking? Or add them on to an existing reservation? Learn how here.

  • A one-way, directional charge will apply and may be paid in advance during booking. If you do not pay in advance, you’ll need to pay when you check-in your pet. In addition to the travel container for your pet, you are allowed either a personal item (8”H x 14”W x 18”L) OR a carry-on bag (10”H x 16”W x 24”L). An additional fee will apply for the carry-on bag.
  • We do not allow pets to be checked as baggage.
  • Be sure to look into the applicable laws, customs, and other governmental regulations, requirements or restrictions of the country, state or territory to which your animal is being transported. This is your responsibility. Also remember to obtain your pet’s required health documents.
  • We recommend that pets have no food or water within four hours of departure.
Pssst... Frontier Tip: Make your trip a little smoother by checking what the state requirements of your destination are regarding animals - some require health certificates, others don’t!
  • Only certain animals are allowed in the cabin:
    • Domesticated dogs and cats must be minimum 8 weeks of age.
    • Domesticated dogs, cats, rabbits, guinea pigs, hamsters, or small household birds may be carried on flights within the United States.
    • The following species are never accepted: Large birds (e.g. parrots, macaws, cockatoos, birds of prey), rodents (including mice, rats, squirrels), beavers, ferrets, reptiles (including snakes), amphibians, spiders, and insects (and please, no lions, tigers, or bears).
    • Only domesticated dogs and cats may be carried to or from international destinations.
  • Pets are allowed in the cabin on all domestic Frontier flights, and on international flights to/from the Dominican Republic and Mexico.
  • You may not sit in row one or an exit row when traveling with a pet.
  • For safety reasons, your pet must remain in the travel container at all times. If your pet is disruptive, it’s up to you to soothe him/her without taking him/her from the pet container.
    Please Note: While it might be tempting to help comfort your pet, most veterinarians advise against sedating pets for travel since the effects of tranquilizers on animals at higher altitudes are unpredictable.
  • We ask that you do not provide food or water to your pet while traveling on the aircraft. The stress of traveling, the motion of the aircraft, and other factors could make your pet uncomfortable.
  • Please Note: No oxygen will be administered to a pet in the event of an emergency.
  • Your pet needs to be harmless, not disruptive, odorless, and require no attention during flight.
  • The travel container must be large enough for the pet to stand, turn around, and lie down in a natural position (you want your pet to be comfortable, don’t you?). The carrier must also fit underneath the seat in front of you. There may be certain seats that cannot accommodate your pet container, but we'll work with you to get a seat assignment with space.
  • Maximum dimensions for a pet container are 18" length x 14" width x 8" height.
  • We recommend the container be a soft-sided case.
  • Your pet must stay in its container at all times.

The United States Department of Agriculture (USDA) regulates the transport of pets within the U.S. While we do not require a health certificate for pets carried in the cabin traveling within the U.S., upon arrival, a certificate may be required by the specific state in which you are landing. For clarification, please call your veterinarian or see the U.S. Department of Agriculture's Veterinary Services.

For international travel, a health certificate is required. Each country may have vaccination requirements beyond the requirements listed here. Consulates can provide more information regarding other diseases for which your pet must be vaccinated.

  • Must be dated based on country on entry:
    • Within 30 days of entry into Puerto Rico
    • Within 10 days of entry into the U.S.
    • Within 15 days of entry in the Dominican Republic
    • Within 14 days of entry into Costa Rica
    • Within 5 days of entry into Mexico
  • Must include:
    • Name and address of the owner
    • Animal species
    • Country of origin/destination
    • Immunization against rabies within 12 months for: adult pets 3 months of age or older for all destinations except Costa Rica and Puerto Rico. Costa Rica defines adult pets as 4 months of age and older. Puerto Rico also defines adult pets as 4 months of age and older and requires immunization against rabies within 6 months. Please Note: The immunization must be administered no more than one year and no less than 30 days prior to international travel. If a pet received a rabies booster less than thirty days before an international flight, proof of the prior rabies shot is required.
  • Additional requirements by country
    • Mexico and the Dominican Republic require a statement on the health certificate that the pet is free from parasites and has been treated for parasite prevention.
    • The following vaccinations are recommended: hepatitis, PIP and leptospirosis.
    • Puerto Rico requires a sturdy collar and two identification tags. The tags should include both your permanent address and telephone number, along with an address and telephone number where you can be reached while traveling.
    • All dogs and cats being transported to and from Canada are required to have both a rabies vaccination and a health certificate.
      • The rabies vaccination certificate must be issued, in either English or French, by a licensed veterinarian from the country of origin. There is no waiting period after the vaccination is administered. Canada does also recognize the three-year rabies vaccination. Please note that if validity date does not appear on the certificate, then it will be considered a one year vaccination.
      • A certificate of health must be in English or French and completed by a licensed veterinarian. It should identify the animal, the dates of vaccination, the manufacturer and the expiration date of the rabies vaccine.
      • In addition to all other documentation requirements, parasitic treatment must be included in the health certificate.
