I received a mailing today from Bob Sobczewski, Manager Onboard Services for United Airlines. Enclosed with the form letter was a three page survey about beverage preferences. Fill it out, mail it back (postage paid) and receive 1000 UA miles in 8-10 weeks. Took me 3 minutes to complete.
Too bad it was just about beverages as I wanted to let them know that we all want an increase in mustard pretzel availability!
