Same here. Even as a just Bronze member around 2008-2012 we were able to get tickets for around 8-12 away games a season. Sunderland, WBA, Stoke, Villa and Everton were regular visits.
Haven't been able to get a ticket for an away day since Middleborough in September 2017 when Sonny got 2.
and like you, I doubt (unless we dramatically fall from grace) we will get to go away again, unless we get a ticket amongst the homeys...
Most away games went to general sale back then, the 4-4 at West Ham went to general sale as did Chelsea every season. I think it was only Arsenal, UTD and Liverpool that you needed points for.
