Just display your boarding pass barcode on the screen of your device at the security checkpoint and when boarding your flight, and you're on your way. Check-in is available starting 24 hours before your scheduled departure.

You should have your boarding pass (either digital or paper) ready to be scanned at four specific stages of your airport journey. 1. Security Checkpoint: In 2026, most airports require a scan of your pass to verify you have a valid flight for that day before entering the TSA or security screening area. 2. Duty-Free and Retail: If you are purchasing items in the "international" section of the terminal, you must often show your pass so the merchant can verify your destination for tax-exemption purposes. 3. Lounge Entry: If you have lounge access, the front desk agent will scan your pass to confirm your eligibility based on class or status. 4. The Boarding Gate: This is the most critical time; the agent or the "e-gate" will scan your pass to officially "board" you into the aircraft manifest. In 2026, many airports use biometric face-scanners at the final gate, meaning once you have scanned your pass at security, you might not need to show it again until the actual plane door, where the flight attendant may glance at it to help you find your seat. However, you should always keep it accessible until you are physically sitting in your assigned seat, as it is your only proof of "right to occupy" that space in the event of a seating dispute.
