  2. Enter your Last Name and Confirmation Code
  3. Tap or click Search
  4. Select Add Seat Selection or Add Baggage
  5. Follow the prompts to complete your request

If you’re checking in online (within 24 hours of departure):

  1. Open the app or visit Frontier Website "My Trip" section  
  2. Enter your Last Name and Confirmation Code
  3. Tap or click Search
  4. Begin the check-in process and add seats or bags as needed
