Booking Limits for Number of Passengers per Transaction

If you need to book travel for a large number of passengers, or for several children and/or infants, or if you are traveling with an unusual ratio of adults to children or infants, the following explanation of our booking rules may be helpful.

Four Age Ranges

Each passenger traveling on Amtrak is initially characterized by age as follows:

  • Adult (16+ years of age)
  • Youth (13-15 years of age)
  • Child (2 - 12 years of age)
  • Infant (younger than 2 years of age)

Reservations for passengers 13, 14 and 15 years old traveling alone cannot be booked on Amtrak.com, but can be made in accordance with the Amtrak Unaccompanied Minor Policy by calling 1-800-USA-RAIL.

In certain circumstances, a passenger who is characterized as a "child" by virtue of age, may be re-characterized as an "adult" for the purposes of determining a fare, if necessary to comply with the Adult-to-Child Fare Ratio rule explained below.

Likewise, a passenger who is characterized as an "infant" by virtue of age, may be re-characterized as a "child" or an "adult" for the purposes of determining a fare, if necessary to comply with the Adult-to-Infant Fare Ratio rule explained below.

Fare-Paying Passengers

Adults, youth and children are considered fare-paying passengers. Passengers characterized as "infants" do not pay a fare.

No More than Eight Fare-Paying Passengers per Transaction

In each online transaction, you may make reservations for no more than eight fare-paying passengers.

You may make reservations for more than eight passengers, but only:

  • when those passengers are "infants"
  • when you otherwise comply with the ratio rules, below

If you exceed the eight fare-paying passengers rule, you can still book travel for your party by completing additional online transactions with no more than eight fare-paying passengers.

Adult-to-Child Fare Ratio Rule

For most Amtrak routes, one child for every adult passenger booked in reservation is entitled to travel at 50% off the standard adult fare. Children exceeding that 1:1 ratio must travel at the standard adult fare. (Infants do not count as "children" for the purpose of determining an acceptable adult/child ratio.)

1 Adult + 1 Child: Child travels at the 50% off fare.

1 Adult + 2 Children: Amtrak.com and the mobile app do not permit booking two children and one adult since it exceeds the acceptable ratio. For the purpose of booking a reservation online, you must instead characterize one of the children as an adult.

2 Adults + 2 Children: Both children travel at the 50% off fare. Up to two children may travel at the children's discount with two adults.

2 Adults + 3 Children: As in the second example above, here one child must be re-characterized as an adult. The remaining children are entitled to travel at the 50% off children's fare.

3 Adults + 3 Children: Since the adult-to-children ratio is not exceeded, all three children may travel at the 50% off fare.

5 Adults + 5 Children: Although the adult-to-children ratio is not exceeded, you may not book travel for all 10 passengers in one transaction since you have more than eight fare-paying passengers.

Adult-to-Infant Fare Ratio Rule

Infants (passengers younger than age 2) are entitled to travel free. This discount is available, however, for only one infant for every adult passenger booked in a given transaction. Any infants exceeding that 1:1 ratio must travel at the children's fare, if available, or at the adult fare, if a children's fare is not available because the maximum number of children are already traveling.

Please note that infants are not entitled to a seat when they travel free. If you wish to ensure that you have seat space for an infant, you must purchase a ticket at the child or adult fare.

1 Adult + 1 Infant: The infant travels free on the adult's lap.

1 Adult + 2 Infants: One infant travels free on the adult's lap. The other infant must travel at the child or adult fare.

2 Adults + 2 Infants: The infants travel free on each adult's lap.

8 Adults + 8 Infants: The infants all travel free on each adult's lap. Since infants do not count as fare-paying passengers, this transaction is permitted by our booking system.

All Rules Applied Together

1 Adult + 1 Child + 1 Infant: This is an acceptable combination. You may book this reservation using our online booking system. The children will travel at the 50% off fare, and the infant will travel free. The infant does not count as a child for the purpose of the 1:1 child-to-adult ratio rule.

2 Adults + 2 Children + 2 Infants: This is an acceptable combination. You may book this reservation using our online booking system. The children will travel at the 50% off fare, and the infant will travel free. The infant does not count as a child for the purpose of the 1:1 child-to-adult ratio rule.

3 Adults + 3 Children + 2 Infants: This is an acceptable combination. You may book this reservation using our online booking system. The children will travel at the 50% off fare, and the infant will travel free. The infant does not count as a child for the purpose of the 1:1 child-to-adult ratio rule.

2 Adults + 3 Children + 3 Infants: You may book this transaction, but you first must re-characterize your passengers.

* The 50% off discount for children is available on most trains. Exceptions and limitations apply.
