You must accept the following notification about traveling with hazardous materials before continuing with check-in.
 
(1) Federal law forbids the carriage of hazardous materials aboard aircraft in your luggage or on your person. A violation can result in five years' imprisonment and penalties of $250,000 or more (49 U.S.C. 5124). Hazardous materials include explosives, compressed gases, flammable liquids and solids, oxidizers, poisons, corrosives and radioactive materials. Examples: Paints, lighter fluid, fireworks, tear gases, oxygen bottles, and radio-pharmaceuticals.
 
(2) There are special exceptions for small quantities (up to 70 ounces total) of medicinal and toilet articles carried in your luggage and certain smoking materials carried on your person. For further information please visit: http://www.faa.gov/about/initiatives/hazmat_safety/
 

Check in online from 24 hours to 45 minutes prior to your flight’s departure time. You will save time at the airport, even if you're unable to print your boarding pass.



What you'll need:

  • Passenger name as it appears in your reservation
  • Frontier Airlines 6-letter reservation code

Checking bags?

Yes

That's great. Check in online and:

  • Get faster service at the airport — simply follow the "Bag Drop" signs to designated lines at the Frontier airport check-in counter where passengers who already checked in online can quickly check their bags until 45 minutes prior to flight departure.* Curbside Bag Drop lines make it even more convenient if you’re flying out of Denver, Las Vegas, or Los Angeles.

  • Pay the lowest checked baggage fees. Your 1st checked bag is always $20 at FlyFrontier.com for Economy fares, but may be higher at the airport. Members of Frontier’s Discount Den save even more with online check-in — pay just $15 for your 1st checked bag! Please note, you will still be responsible for paying any oversized and excess baggage fees at the airport. Some items, such as assistive devices, are exempt from baggage fees, which we can only waive at the airport. All bags must be checked-in at the airport at least 45 minutes to departure.

  • Pay lower carry-on baggage fees. If you haven’t already paid for your carry-on, it will cost just $30 at FlyFrontier.com online check-in if you are traveling on an Economy fare purchased on or after April 28, 2014, or a Basic fare. Carry-on bag fees will be higher at the airport.

Note: Carry-on bags may not exceed 10" height x 16" width x 24" length. Oversize carry-on bags are subject to a gate check fee at the airport departure gate.

Everyone is permitted to take onboard the aircraft one personal item not to exceed 18" x 14" x 8".

Want to choose your own seat?

If you are traveling on an Economy fare and want to choose where you sit, you can pay a fee to select an available seat during online check-in. Otherwise, you will be randomly assigned a seat and your party may be separated.

If you are on a Classic Plus fare, you may select any available seat for no charge.
