CHICAGO (AP) -- United Airlines said on Monday that traffic dropped 1.6% in January, a month when bad weather hobbled airlines by forcing thousands of flight cancellations.

The cancellations pushed down United's flying capacity by 2.8% for the month. Because capacity fell more than traffic, United planes were actually a little fuller. It said occupancy rose one percentage point to 80.9%. The biggest gains were on domestic flights, where occupancy rose 1.5 percentage points to 83.8%.

United used to report monthly changes in passenger revenue, a key metric for airlines, but said that beginning with January it will only report that figure quarterly.

Shares of parent company United Continental Holdings fell 43 cents to close at $45.11 on Monday.
