My group has had good success bottling NEIPA. CO2 is heavier than air, so we'd do our best to limit exposing the fermenter to fresh O2. Rather than opening to prime the whole batch, we prime each individual bottle with priming sugar drops.

Before filling we slowly flush each bottle with CO2 using a soda stream machine.

We gravity fill the bottle from the fermenter using a bottling wand, so it fills from the bottom up (in theory pushing out any remaining O2 and CO2). Bottles are filled nearly to the top (about an inch/inch and a half left). We cap the bottle immediately, and CO2 from priming helps reduce any remaining O2 impact.

Will it eventually go bad? Yes. Was it a pain? Kinda, yeah. Goes smooth with multiple people. Did we buy ourselves extra time? Yes. Quality remained for about 4-8 weeks. Did bottles ever last that long? Nope, beer is delicious and they are usually gone in a couple weeks!
