Delta offered the triple-points promotion to "increase awareness" of the new Chicago service, says spokesman Kent Landers. Fliers can earn 4,400 miles for a New
York-Chicago round trip through August. United matched the offer, and American began a similar promotion 16 days later.
"Delta's primary target is to steal people from American," says
consultant Brett Snyder, a former United and America West Airlines manager who runs the CrankyFlier blog. "American responded with the triple points because they don't want even one single flier to
switch to Delta."
