Boarding continued for a few minutes, but then the pilot decided everyone should disembark so that the cleaning crew--which had to be summoned from a different terminal--could use chemicals whose odors might cause the rest of us to throw up, too. At this point Port Authority protocols kicked in--which did not prevent pax from complaining that this was somehow all DL's fault for allowing the first barfer on the plane to start with--and that included calls in to the CDC to make sure that there couldn't be something in the air that was making everyone sick. (The answer was no.)

Not a good day for many people, but for me a happy outcome: I'd missed the UGs on both this and my connecting flight, but with the delays and cancellations ended up in F on both my new flights.
