Final answer:
In most cases, a 17-year-old would not be able to request Unaccompanied Minor service (UMNR) as they are considered adults for travel purposes; hence, the statement is generally false.
Step-by-step explanation:
The question, "17 years old can request UMNR," refers to whether a 17-year-old can request Unaccompanied Minor service (UMNR) typically offered by airlines. Commonly, UMNR service is available for minors who are traveling alone, but there are age limitations which vary by airline. Most airlines offer this service to minors who are between the ages of 5 and 14 years old for domestic flights, and between 5 and 17 years old for international flights. However, once a traveler is 17 years of age, they are usually considered an adult for the purposes of travel, so they would not be able to request UMNR services. Therefore, the statement is generally considered false.
