My wife got today:
Discount: Valid for one discount of 20% off all base fare levels published at alaskaair.com.

Passengers: Up to two people per Discount Code, traveling together and booked and ticketed at the same time in the same reservation and at the same fare. The recipient of this discount code must be one of the travelers.

Does anyone know if they enforce it, that "The recipient of this discount code must be one of the travelers."?
