A landmark Pepsi sign along New York City's East River will also promote JetBlue for the next six weeks, and critics are finding it hard to swallow.

An illuminated blue logo advertising the airline was added to the 60-foot (18-meter) Pepsi-Cola sign in Long Island City, Queens, this week. The new signage celebrates a partnership in which JetBlue will serve PepsiCo drinks on flights.

The city Landmarks Preservation Commission issued a permit for the JetBlue logo through Oct. 1. But City Councilman Jimmy Van Bramer, a Democrat who represents the area, says some constituents are complaining. Van Bramer says that even a temporary JetBlue sign "shouldn't be there."

Nancy Rooney, a PepsiCo vice president of marketing, says the iconic Pepsi-Cola sign is "the perfect symbol" to celebrate Pepsi's JetBlue partnership.
