BWI closed Checkpoint A a couple of hours early last night due to excessive TSA call-outs. No word on whether this was a one-off or is anticipated to be a regular thing, but it seems to me that the problem can only get worse as the shutdown continues.

Things are looking pretty bad all over the US for the next few days, as a large snowstorm is moving through the country and has already caused several thousand flight cancellations. Once things get moving again, I would think the backlog of stranded travelers will cause a spike in the number of people presenting themselves for screening, and with TSA short-handed due to these call-outs, that will probably cause longer lines at the remaining checkpoints.
