If heavy rail or intercity bus service is approved by an agency as a mode of employee travel, an agency shall pay for, and an employee shall only be reimbursed for, the cost of the lowest-price coach class heavy rail (for example, Amtrak) or intercity bus service that reasonably meets the travel needs of the employee, unless another class of service is authorized under § 4007.3.
To determine and obtain the lowest-price coach class fare that reasonably meets the travel needs of the employee, the employee shall:
An agency may approve a class of service other than basic, coach-class service if:
Mere preference or convenience is not an acceptable factor for an agency to consider.
An employee may upgrade to other than basic, coach-class service, or to preferred seating or service in coach-class accommodations, at the employee's personal expense. The employee shall be responsible for the payment of the cost of any upgrades.
