Tom.....there has always give and take in our pwa.
There was no memrat at delta until the 90's. The mec and company went into a room and shook hands on the pwa.
Very cozy. After all memrat can get messy.....from the concerned parties view im sure.
The history of never rejecting a ts speaks to the mindset of cooperation and acceptance of this pilot group that the 'best' deal....for delta and the pilot group......had been struck.
