United Ads Return to the Air

United Airlines has returned to TV for the first time in about a year with new spots that promote its “Go. Go. Stay” fare promotion. The work will run through the end of the week. The spots will air in Chicago, Denver, Los Angeles, San Francisco and Washington, as well as in Seattle, Boston and New York, and tout a tie-in with Hilton Hotels Corp. The ads were created by Fallon in Minneapolis. The effort also includes newspaper and radio. Spending was not disclosed.
