Yesterday morning (Sunday) I transited through JFK as I had to spend the night in a hotel at JFK due to bad weather at DCA. I arrived at the airport around 10:30 a.m. to find, to my pleasant surprise a deserted security checkpoint. As usual, I took out my laptop and my CPAP and put them in separate bins. For the first time, they did not take a swab off my CPAP to test it for explosives.
