Which option is not available for a traveler to update their profile in DTS?

Updating personal traveler information in DTS is an integral part of ensuring that profiles are accurate and up to date. Travelers can typically adjust their login information to maintain security, access quick links for efficient navigation, and change various profile details, including contact information and preferences. However, accessing administrative settings typically falls under the responsibilities of those who manage accounts and permissions rather than individual travelers. This means that while the other options involve steps a traveler can take to update their profile or access features, administrative settings are not typically available for personal updates by travelers, making it the correct choice in this context.
