Amtrak (12:30 p.m.) -- About 15 percent of trains out of Washington, D.C., were canceled today. The issue was equipment in wrong places and trouble getting employees where they needed to be. It was having a ripple effect throughout the system -- affecting trains going south as well as north. Trains that were running were operating at full capacity today. Some cancelations included Acela Express service. There probably will be some residual effect for Monday.
American Airlines (12:30 p.m.) -- Cancelled 127 flights, plus another 40 for American Eagle. All morning operations at LGA, JFK and BOS were canceled. Hoped to resume operations there this afternoon.
Delta (12:30 p.m.) -- Hundreds of flights remained canceled. Hope to start resuming operations in the afternoon, but didn't expect planes to really start flying until Monday. The issue wasn't the runways -- but rather getting planes and workers where they needed to be. Officials were trying to figure out if they can run more flights or use bigger planes on some routes to accommodate passengers.
Continental (12:30 p.m.) -- Cancelled 50 flights this morning. Other flights were operating with one- to two-hour delays, depending on location and de-icing. Monday looked better domestically for a more complete schedule. However, there could be problems with flights coming from Europe -- which has its own weather problems.
JetBlue (12:30 p.m.) -- Cancelled 205 out of 682 flights -- mostly JFK and Boston. The airline's goal was to be up and running "full steam" Monday.
Air Tran (12:30 p.m.) -- 32 cancellations today. No more expected.
