Delta passengers can't check in because of problem with website, mobile app and kiosks

Passengers on Delta Air Lines Monday afternoon are unable to check in for their flights because of a malfunction with the airline's website, mobile app and airport kiosks.

Travelers from different parts of the country are complaining about the problem on Twitter. The Atlanta-based airline is not immediately saying how widespread the outage is.

The computer problems come on a day with massive flight delays and cancelations in New York and Boston due to a winter storm.

Tracking site FlightAware says Delta canceled 200 of its mainline flights Monday and hundreds of others belonging to regional airlines flying under its name.
