Whether you’re a grandparent, aunt/uncle, family friend, coach, or chaperone, traveling with a minor who isn’t your legal child can come with extra questions at check-in, boarding, and border control. The best way to avoid delays (or a denied boarding situation) is to carry the right paperwork—every time.

📄 Must-Have for ALL Travel Types

Regardless of cruise, flight, or resort, plan to bring the following documents:

• Notarized Parental Consent Letter
  • Signed by both parents/legal guardians (when applicable)
  • Includes:
    • Child’s full name & date of birth
    • Travel dates & destination(s)
    • Name(s) of traveling adult(s)
    • Permission for medical treatment
    • Parents’ contact information
• Copy of Parents’ IDs (driver’s license or passport)
• Child’s Birth Certificate
  • Helps show parent/guardian information and legal guardianship
• Medical Authorization Form
  • Allows you to seek treatment if needed

✈️ Flights (Domestic & International)

🇺🇸 Domestic Flights (U.S.)

• TSA does not require ID for children under 18, but:
  • Airlines may ask for:
    • Birth certificate (proof of age)
    • Consent letter (highly recommended)

🌎 International Flights

• Child MUST have a passport
• Notarized consent letter is strongly recommended (and often required)
• Some countries require:
  • Additional entry forms
  • Proof of relationship or written permission to travel

🚢 Cruises

🛳️ Closed-Loop Cruises (U.S. departure/return)

• Birth certificate may be accepted instead of a passport (depending on the itinerary and cruise line)
• BUT if the child is not yours:
  • Passport is HIGHLY recommended
  • Notarized consent letter is required by most cruise lines

🌍 Cruises Visiting Foreign Ports

• Passport required
• Consent letter is mandatory
• Some cruise lines may deny boarding without it

🌴 All-Inclusive Resorts (International)

• Passport required
• Notarized parental consent letter required
• Resorts may request:
  • Emergency contact information
  • Medical authorization

⚠️ Important Tips

• If only one parent signs (for example, a single parent situation), bring:
  • Custody documents or a death certificate (if applicable)
• If last names differ:
  • Bring proof (a birth certificate often helps)
• Keep both:
  • Printed copies (easy to hand over at a counter)
  • Digital backups (phone + email/cloud)

🧳 Pro Tip

Even when something is “not required,” airlines, cruise lines, resort staff, or border agents can still ask questions—especially when an adult is traveling with a minor who has different last names. Having complete documentation helps prevent delays and can protect your trip from being derailed at the last minute.
