It's definitely not limited to the "regional" level which makes this article misleading. Pilots and flight attendants at all types of airlines use crashpads.

There are good and bad crashpads around. I happen to have a good one with my own bed, storage area, full kitchen, two bathrooms, computer, wifi, television/living room, maid service plus transportation to the airport and back twice an hour. Very nice and clean. The most I have ever seen in mine at one time is 10 people (but usually 5 or less) scattered on three different floors and rooms.
