If you are under 25 and planning to rent a car on St. Thomas, there are additional requirements and surcharges you need to be aware of. Alamo, Enterprise, and National all have age policies at Cyril E. King Airport (STT). Here is what young drivers need to know.
Minimum Age to Rent
The minimum age to rent a car at STT from Alamo, Enterprise, or National is typically 21. However, drivers between 21 and 24 are subject to an underage surcharge that is added to the daily rental rate.
Underage Surcharge Amounts
The underage surcharge typically ranges from $20 to $30 per day, depending on the rental brand and location. This surcharge applies for each day of the rental and is collected at the counter. The exact amount should be disclosed when you book.
Which Vehicles Are Available to Underage Drivers?
Drivers under 25 may be restricted from renting certain vehicle categories:
- Luxury and exotic vehicles are typically off-limits
- Large passenger vans may be restricted
- Premium SUVs may have age limits
- Standard economy, compact, midsize, and standard SUVs are generally available
How to Minimize Costs
- Join the rental brand's loyalty program before booking
- Book in advance to lock in the best base rate
- Check if corporate accounts waive the underage fee
- Compare all three brands — surcharges vary
Required Documents for Underage Drivers
- Valid driver's license (held for at least one year in most cases)
- Credit card in the driver's name
- Proof of insurance (if declining rental coverage)
- Reservation confirmation
Why the Surcharge Exists
Underage surcharges reflect statistical risk — younger drivers are involved in more accidents. The surcharge helps offset the higher insurance costs that rental companies face for young renters.
Tips for Young Travelers
If you are traveling with someone 25 or older, consider having them be the primary driver to avoid the surcharge. However, all drivers must still be listed on the agreement.
