Sad to see it go.

As to a replacement, maybe one of the seven older 763s not slated to get Polaris and retired could get a new lease of life? That 752 had 169 seats (16J/153Y). Reprieving a 763 and converting to High J would be 167 seats though at 46J/22P+/99Y. I can see that working for a business heavy route. And for a mostly Y heavy route with potential (say EWR-MAN or IAD-DUB?) put one of the non P+ 763s (30J/184Y) and if necessary sell lots of TODs.
