New York City and Chicago tourism officials, along with American Airlines, unveiled a new deal Wednesday to promote visits between the two cities.

The upshot: $89 airfare each way between the two cities. But: You've got to purchase the tickets from American Airlines by the end of the day Oct. 22. You can travel between January 5, 2011 to February 25, 2011 with embargoes from January 15-17 and February 18-21, 2011.

Some of the NYC promotions taking place this winter include the first-ever Broadway Week offering two-for-one tickets to more than 40 of Broadway's hottest shows (January 24-February 10); the upcoming NYC Restaurant Week Winter 2011 offering visitors prix-fixe meals at nearly 300 of the City's high-end restaurants (January 24-February 6); and the Off-Broadway promotion "On the House" offering theater enthusiasts two-for-one tickets to some of the City's most celebrated Off-Broadway shows (January 24-February 13). In addition, more than 80 of the City's top hotels will offer up to 35 percent off their best available rate from January 2 to February 28 when travelers book between October 15 and November 2. Further details can be accessed at nycgo.com.
