Flying CVG-FLR late January w/ TATL on DL228 (looks like old 76W but DL seat selection closer resembles 76K...) to CDG. Return is on AF378 (359) Total cost from Main to PS is $600 RT.

Outbound TATL is J9 C9 D9 I9 Z9 P9 A9 G9 W9 S9
Inbound AF is J9 C6 D0 I0 Z0 W9 S9 A8

I was convinced I wanted PS for the extra room but now I'm wondering if I'll have a decent chance for better price to upgrade (PS or D1 even though outdated) OR have enough room on the flight in Main that I won't really need PS. Trying PS on the AF 350 would be nice, but like the outbound, I could always hope for an offer to upgrade the AF flight (or add PS for just the AF flight if given the option). I am Jack's extreme indecision...

Any thoughts or advice?
