About Checking In

Frontier offers three check-in options:

  1. Check-in online at FlyFrontier.com — read below to find out why this is your best check-in option
  2. At the airport using self-service kiosks in many airports
  3. At our full-service check-in counters

Read below for details on each of these options plus information on what to do after check-in.

Check-In Cutoff

You must have your printed boarding pass in hand and have any baggage checked-in by the following cutoff times:

  • 45 minutes before your departure for domestic flights
  • 60 minutes before departure for international flights

In our Denver hub, please be in line to check-in at least 2 hours prior to departure to ensure you are checked-in with a boarding pass in hand no later than 45 minutes prior to your flight's departure.

Please be at the gate and ready to board no later than 15 minutes before departure or your seats may be released. We recommend arriving at the airport two hours or more in advance of your flight.

Check in online from 24 hours to 60 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.

Check In

What you'll need:

  • Passenger name as it appears in your reservation

Checking bags?


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 $25 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 $20 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.

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.

Service Counter Check-In

If you need some extra help with the check-in process, our customer service agents are always available to help get you going with traditional counter check-in, available in all airports. If you are traveling on Classic Plus fare or if you are a Summit or Ascent level member of EarlyReturns, we invite you to look for the Priority Check-in lane at our ticket counters.

After Check-In

Remember, your gate assignments and departure times can change due to operational requirements, so be sure to stay updated by checking the flight monitors at the airport.

We recommend being at the gate well ahead of your flight. We usually begin boarding about 30 to 35 minutes before departure time. In any case, you must be at the gate ready to board 15 minutes prior to scheduled departure or your reservation may be cancelled and your seats may be released to other passengers.

Frontier boards our aircraft using Zone Boarding to simplify the announcements at our gates and to speed up the boarding process. With Zone Boarding, we board in the following order:

  1. Passengers with Special Needs — Including anyone needing wheelchair or other boarding assistance and unaccompanied minors. For discretion, no announcement will be made for special needs boarding. If you require assistance with boarding, please check-in with the Frontier agent when you arrive at the gate so that they know you desire to board first.
  2. Priority Boarding and Zone 1 — Offered to Ascent and Summit level members of Frontier's EarlyReturns frequent flyer program, as well as anyone traveling on a Classic Plus ticket. Zone 1 also includes any military personnel in uniform and any passengers who have purchased a seat in STRETCH seating.
  3. Courtesy Boarding — Offered to families traveling with small children (under 3 years of age) and any other passengers requiring additional time or assistance with boarding.
  4. Zones 2 through 4 — Called in order, these zones move progressively from the aft of the aircraft forward for all passengers who are not in Zone 1.

Please note that in select airports where we board from the ramp using both the front and rear aircraft doors, the boarding order may be changed to expedite boarding through both doors of the aircraft.
