Vail Resorts says lift ticket revenue, skier visits and spending at its six resorts are up so far this ski season.

The Broomfield, Colo.-based company acquired Northstar-at-Tahoe in October and also owns Heavenly in the Lake Tahoe area, plus Vail, Beaver Creek, Breckenridge and Keystone in Colorado.

It says that through Thursday, skier visits were up about 10.1 percent from the comparable period last season, when looking at the numbers as if the company had owned Northstar last season too. It says lift ticket revenue was up 7.4 percent, ski school revenue was up 11.5 percent, and retail and rental revenue was up 17.5 percent.

Exact dollar figures weren’t released Monday.
