The Transportation Security Administration is responsible for overseeing the five security checkpoints at McCarran International Airport -- three in Terminal 1 and two at Terminal 3.
A/B Security Checkpoint: Located on Level 2 of Terminal 1 above the Ticketing/Check-In area. This checkpoint has 8 screening lanes and serves airlines operating from the A and B Gates.
C Gates Annex: Located on Level 2 of Terminal 1 above the south end of the Ticketing/Check-In area. This checkpoint has 13 screening lanes and serves airlines operating from the C Gates. A pedestrian bridge located just past the checkpoint connects the C Gates to the A and B gates, so depending on which airline you choose, this may be a convenient option for travelers departing from the B Gates as well.
C/D Security Checkpoint: Located on Level 2 of Terminal 1 above Baggage Claim. The D Gates side of this checkpoint has 17 screening lanes and serves airlines operating from the D Gates. The C Gates side of the checkpoint has 2 screen lanes and services airlines operating at the C Gates. If you are traveling on Southwest Airlines and get your boarding pass in advance and are not checking any luggage, this may be a convenient option for you.
Level 2 Checkpoint: Located on Level 2 of Terminal 3, this checkpoint has 14 screening lanes and serves domestic and international airlines operating at T3.
Level Zero Checkpoint: Located on Level Zero of Terminal 3, this checkpoint has 17 screening lanes and will serve airlines operating from the D Gates. This checkpoint is currently not open.
TSA Security Requirements
All passengers must pass through one of these five screening checkpoints before they can proceed to airline departure gates. At passenger screening locations, TSA security officers will process you and your carry-on bag. To proceed through screening, you will need a current government-issued ID and a valid boarding pass for a flight. To help you prepare for screening:
- Learn what you can take in a carry-on bag;
- Have liquids and gels in containers of three ounces or less, and have the containers in a one-quart-sized, zip-top plastic bag;
- Remove the plastic bag from your carry-on bag and put it in a screening bin;
- Place metal objects, such as coins and keys, in your carry-on bag;
- Put laptop computers in a screening bin;
- Remove shoes, jackets and belts and put them in screening bins.
The TSA encourages travelers to become familiar with security regulations before coming to the airport. For information about the security requirements, prohibited items, and questions about baggage screening, visit the Transportation Security Administration Web site.
McCarran International Airport participates in TSA PreCheck, an expedited screening initiative available at Terminal 1 and Terminal 3 for the following airlines:
- Air Canada
- Alaska Airlines
- American Airlines
- Delta Air Lines
- Hawaiian Airlines
- JetBlue Airways
- Southwest Airlines
- United Airlines
- US Airways
- Virgin America
TSA PreCheck enhances aviation security by placing more focus on pre-screening individuals who volunteer to participate in order to expedite the travel experience. TSA is partnering with U.S. Customs and Border Protection (CBP) as well as U.S. air carriers as part of this pre-flight screening initiative. Certain frequent flyers from participating airlines and certain members of CBP's Trusted Traveler programs, including Global Entry, SENTRI, and NEXUS who are U.S. citizens are eligible to participate.
If TSA determines a passenger is eligible for expedited screening, information is embedded in the barcode of the passenger’s boarding pass. TSA reads the barcode at designated checkpoints and the passenger may be referred to a lane where they will undergo expedited screening, which could include no longer removing the following items:
- 3-1-1 compliant bag from carry-on
- Laptop from bag
- Light outerwear/jacket
TSA will always incorporate random and unpredictable security measures throughout the airport and no individual will be guaranteed expedited screening.
