UpgradeMe recognizes that Delta's A310s from the PanAm days were all retired ~25 years ago.
Perhaps you meant A321 (all new) or A319 or A320 (all refurbished). Pretty much so long as you avoid Delta 717s, MD-88s and MD-90s you will get AVOD at every seat and 2Ku wifi (a big advantage over Alaska, if you need wifi).
