WTOP’s Hank Silverberg reports that the flight schedule in and out of Reagan National Airport is returning to normalcy this morning after a pipe burst yesterday, flooding Terminal C. US Airways, which operates in the affected terminal, resumed flights at 10 a.m. — but long lines and waits are to be expected due to the backlog created by the shutdown last night. Silverberg notes that it took a hundred people working through the night to clean up the mess caused by the flooding; all complicated by the fact that electricity to the terminal was shut off throughout the evening. Those flying in and out of DCA today — especially on US Airways — are encouraged to call (the US Airways hotline: 800-428-4322) and double-check on the status of potential delays.
