I rarely use those vouchers and give away most of them to my family while saving a few in case I am stuck on a RJ. However, while waiting on the GS line to board a flight on Monday from ORD to NRT, I noticed another passenger giving away the few vouchers he had left to about 12 soldiers who were lined up separately away from the long group 1 line. What a great idea! I searched through my bag and discovered I had a sheet left as well and made sure I dispersed them.
