I just recruited three relatives who are over here and will be flying back to the states shortly on NW and KL to distribute the flyers while on that trip.

I had two work colleagues in town who have always specified NW to our travel office as their airline choice and are have been NW elites for years who are so dejected about the airline's DL future they say they are not even going to bother specifyiing NW as their airline of choice any more, which means our travel office is sure to put them on its choice, UA. If by some circumstance the travel office books them on NW without them requesting it, I can probably motivate them to also pass out some flyers, but if they are on UA, I can't see them being as motivated to do so.
