This is wrong, their allocation was ~5700 and the official figure 5501. The stand holds ~6000, they didn't have the front row (155) and around 200 restricted view.
They were only allocated 5,700 and I swear it was announced 5,551 which would leave it at 13k Home fans

Newcastle websites said they had sold 5,900 and our official website gives the away end at over 6,200.
I'm unsure as to where you're getting this from mate, here's an article from Newcastle's site which states clearly their full allocation was 5700: http://www.nufc.co.uk/articles/20161006/ticket-alert-extra-barnsley-tickets-secured_2281670_5955784 And our official site says the away end holds 6238 yes, but the article's from 2014 and still refers to all the old sponsors' names so who knows how much truth there still is in it.
