Whether or not bruceb speaks from authority or delusions of grandeur (if the latter, bruceb, I would recommend impersonating the spokesman of a more commendable organization, such as North Korea), Delta's position towards PMs is:

Get drunk on your own hooch so you don't feel the pain of buying a first-class ticket

or

Get drunk on our hooch at the CRC so you don't feel the pain of our coach product.
