Not really. We scanned our own boarding passes prior to boarding; were told to observe the floor markings to keep proper distance. We borded from the back to front of the plane.
Jet Blue served a plastic package with a small bottle of water and a small bag of cookies; no other food or beverage service to minimize personal contact.
PJIA was very well organized with security screening, etc. I was pleasantly surprised by the whole experience. Jet Blue was gone before when the other flights came in, for which I was grateful!
