For all your trips to and from, or within, the territory of the United States, your booking must contain the exact information as shown on your Passport. The TSA (Transportation Security Administration) requires that all reservations include:
- Names and Last Name(s) exactly as they appear on your passport
- Date of birth
During check in for boarding at the departure airport, the TSA will determine in real-time, whether the registered information matches the booking information and if it meets the required conditions.
If the information is not the same the TSA will deny access to the air service, regardless of the airline.
Both the authorities and us as airlines have mechanisms to safeguard the privacy of your personal details.
For more information you can check TSA or directly with the Department of Transportation, Aviation Consumer Protection Division.
