Season ticket holders don't have priority for a normal euro away, its based on a credit system. Those who attended all 3 champions league away games plus Ajax home and away will have 5 credits and get preference (doesnt matter if you are a season ticket holder, exec or one united member). Then it works on a sliding scale 4 credits, 3 credits etc. Im guessing there will not be a huge demand for this one, i reckon everyone who applies will get one (if the allocation is not ridiculously low).
