## Understanding TSA PreCheck  
TSA PreCheck is a trusted traveler program operated by the Transportation Security Administration in the United States. It is designed for passengers who are considered low risk and want a faster security process.  

### Benefits of TSA PreCheck  
- Access to dedicated security lanes with shorter wait times

## Eligibility for TSA PreCheck  
Before adding TSA PreCheck to your Allegiant Air reservation, you must be enrolled in the program.  

### Enrollment Process  
1. Complete an online application through the TSA website.  
2. Schedule an appointment at an enrollment center.  
3. Provide identification documents and fingerprints.  
4. Pay the application fee.  
5. Wait for approval and receive your Known Traveler Number, often called KTN.  

Once you have your KTN, you can add it to your Allegiant Air profile or directly to your flight reservations.

## Allegiant Air and TSA PreCheck  
Allegiant Air is a US based low cost carrier that participates in the TSA PreCheck program. This means that if you have TSA PreCheck approval and your KTN is linked to your reservation, you can use the expedited lanes at most US airports served by Allegiant Air.

## How to Add TSA PreCheck to Allegiant Air  

### Step 1: Locate Your Known Traveler Number  
After approval, you will receive a KTN. This number is essential because it connects your traveler profile to the TSA system. Keep it accessible when booking flights.  

### Step 2: Add KTN During Booking  
When booking a ticket on the Allegiant Air website or mobile app, you will see a section for passenger information. Enter your KTN in the field provided. Double check the number to avoid errors.  

### Step 3: Update Existing Reservations  
If you already booked your flight and forgot to add your KTN, you can still update your reservation.  
- Log in to your Allegiant Air account.  
- Go to Manage Travel.  
- Select your reservation.  
- Edit passenger details and add your KTN.  
- Save the changes.  

You can also call Allegiant Air customer service and request that they add your KTN to your booking.  

### Step 4: Add KTN to Your Allegiant Travel Profile  
If you are a frequent flyer with Allegiant Air, add your KTN to your travel profile. This ensures that future bookings automatically include your TSA PreCheck information.

## Checking Your Boarding Pass  
Once your KTN is added, your boarding pass should display the TSA PreCheck indicator. This is usually marked with the words TSA PRE or a similar symbol.  

### What to Do if It Does Not Appear  
- Verify that your KTN was entered correctly.  
- Ensure that the name on your booking matches the name associated with your TSA PreCheck enrollment.  
- Contact Allegiant Air customer service if the indicator is missing.

## Using TSA PreCheck at the Airport  
On the day of travel, look for TSA PreCheck lanes at the security checkpoint. Present your boarding pass with the TSA PreCheck indicator and proceed through the expedited lane.  

### Important Notes  
- TSA PreCheck is only available at participating US airports.  
- Children under 12 traveling with an eligible adult can also use TSA PreCheck lanes.  
- If you are flying internationally, TSA PreCheck applies only to the US departure airport.

## Common Mistakes to Avoid  
1. **Incorrect Name Entry**  
   The name on your booking must match the name on your TSA PreCheck enrollment. Even small differences can cause issues.  

2. **Forgetting to Add KTN**  
   Many travelers forget to add their KTN when booking. Always double check before finalizing your reservation.  

3. **Assuming TSA PreCheck Works Everywhere**  
   TSA PreCheck is a US program. It does not apply at airports outside the United States.

## Tips for a Smooth Experience  
- Save your KTN in a secure place for easy access.  
- Add your KTN to your Allegiant travel profile to avoid repeating the process.
