Tex. Government Code § 660.141: REIMBURSEMENT IN CERTAIN CIRCUMSTANCES INVOLVING LOWER AIRFARES.

The comptroller by rule shall allow extra travel time to be claimed for computation of reimbursable travel expenses if a state employee obtains an airfare that is lower than the fare that would have been paid for travel for the same purpose but for a shorter period pursuant to this chapter, the result is a cost saving to the state, and the employee's additional absence is determined by the employing agency not to be detrimental.

Amended by Acts 1999, 76th Leg., ch. 280, Sec. 7, eff. Sept. 1, 1999.
