Midwest Airlines check-in

What options do I have to check-in for my Frontier Airlines flight?

Frontier Airlines offers you the choice of 3 check-in options:

  • Online Check-in.
  • Kiosk Check-In.
  • Service Counter Check-In.

What are the check-in time limits for Frontier Airlines flights?

The Online Check-in time limit is 60 minutes prior to your flight's departure time. The airport check-in time limits for Frontier Airlines flights, whether or not checking bags, are:

  • 45 minutes before departure time – domestic flights (within the continental United States and Alaska).
  • 60 minutes before departure time – all international flights.

Frontier Airlines reserves the right to cancel the reservation and pre-assigned seat of any passenger who fails to comply with the airport check-in time limits. Frontier Airlines advises passengers traveling internationally to arrive at the airport at least 2 hours prior to departure, thus allowing sufficient time to complete all necessary requirements.

Where do I check-in when my itinerary involves a connection to another airline?

You must check-in with the airline operating the first flight segment of your travel itinerary. The operating carrier will be identified on your ticket and in your reservation. For example, if your Frontier Airlines ticket includes a Great Lakes connection, depending on your itinerary, you may have to check-in with Frontier Airlines for one direction of your travel and check-in with Great Lakes Airlines for the return portion of your trip.

When connecting from Frontier Airlines to American Airlines, Icelandair, or Korean Airlines, passengers can receive their boarding passes through to their final destination when checking in at a Frontier ticket counter. Also, American Airlines, Icelandair, and Korean Airlines are able to issue a boarding pass for your connecting Frontier Airlines flight if you travel itinerary starts with a flight operated by them.

Online Check-in

For all Frontier Airlines flights, Online Check-in is available within 60 minutes to 24 hours of the departure time. Even if you're unable to print your boarding pass, Online Check-in can help save time at the airport. To start checking in online, you need the passenger’s name (as it appears on your reservation) and the Frontier Airlines six-letter reservation code.

If you travel without checked baggage, just be sure to have your printed boarding pass and photo I.D. when you arrive at the airport and head straight for security.

If you plan to check baggage, Online Check-in allows you to pre-pay baggage fees, and, upon arrival at the airport, you can follow the "Bag Drop" signs to designated lines1 available at all airports served by Frontier Airlines where you can drop your bags. You will have to pay any oversized and excess baggage fees at the airport. Also, if you want to check an item exempt from baggage fees, the fee can be waived only at the airport.

Also, Curbside Bag Drop lines are available, when you are departing from Denver, Las Vegas, Los Angeles, and Washington, D.C. – Reagan National, to drop your bags, pay baggage fees and obtain your boarding pass after you’ve checked in online.

Kiosk Check-in

Kiosk Check-in is available in select airports where you can use self-service kiosks to view your itinerary, check yourself in, check bags, and print your boarding pass. To start check-in at a self-service kiosk, you need to enter your Frontier Airlines six-letter reservation code, scan your confirmation, or swipe your ID, passport, or credit card.

Service Counter Check-in

Ticket counters within every airport terminal are available for passengers needing assistance to check-in. Frontier Airlines Customer Service representatives will assist you with any baggage you're checking, answer any questions you may have, and provide you with a valid boarding pass. Also, Priority Check-in lanes2 are available at all airports if you are traveling on a Classic Plus ticket or if you are a Summit or Ascent member of EarlyReturns.

2Except Branson (BKG), South Bend (SBN), and Grand Rapids (GRR).


You must be present at the departure gate and ready to board at least 10 minutes prior to departure, otherwise your reservation may be subject to cancellation, and your seats assigned to other passengers. Frontier Airlines recommends arriving at the gate earlier, considering that boarding usually begins 30 to 35 minutes before departure time. Always remember to stay updated by checking the flight monitors at the airport, because your gate assignments and departure times can change due to operational requirements.

Using Zone Boarding to simplify the announcements and speed up the boarding process, Frontier Airlines will board passengers in the following order:

  • Special Needs Boarding (no announcement) – anyone needing a wheelchair or other boarding assistance and Unaccompanied Minors. Because Frontier Airlines doesn't announce Special Needs Boarding, when you arrive at the gate, you must check-in with the Frontier agent if you require assistance with boarding.
  • Priority Boarding and Zone 1 – Priority Boarding for Ascent and Summit level members of Frontier's EarlyReturns frequent flyer program and passengers traveling on Classic Plus tickets. Zone 1 includes passengers who have purchased a seat in STRETCH seating and any military personnel in uniform.
  • Courtesy Boardingfamilies traveling with small children (under 3 years of age), children traveling alone, and any other passengers requiring additional time or assistance with boarding.
  • Express Boarding – passengers in Zones 2, 3, and 4 who will not be utilizing overhead space.
  • Zone 2 – passengers seated in SELECT Seating.
  • Zone 3 – passengers seated in rows 20 and above.
  • Zone 4 – all remaining passengers.

To expedite boarding, Frontier Airlines may change the boarding order in select stations where both the front and rear aircraft doors are used for boarding from the ramp.
