You still can't get tickets legitimately unless you are at least a member. I was going to go to Palace, but they aren't going to general sale
I let my membership lapse last season as it no longer seemed necessary and got tickets to the half dozen or games including three London aways without any bother.
Funnily enough has been harder this year with no joy on the London games, although iirc there were some right crappy dates and kick off times last season facilitating some GS being available.
I don’t do FB but might have to have a shufti on there, although this season for London aways there’s only Palace (I’m away for that) then W Ham on 11th April, then it’s onto the championship next year and I guess that knocks back the need to renew the membership even further.
