What does UM stand for?

• A. Weather
• B. Unaccompanied Minor
• C. Regular Reserve
• D. Visual Service Indicator

Answer: (B)

In airline terminology, UM stands for Unaccompanied Minor. This label marks a child traveling without a parent or guardian, triggering extra supervision and step-by-step handling from check-in through arrival. Airlines assign staff to escort the traveler during boarding and hand them to the designated guardian at the destination, with policies varying by carrier (age ranges and fees). The other options refer to unrelated concepts—weather, a reserve category, or a service indicator—so they don’t match the common use of UM in passenger operations.
