Everton regularly take large numbers away from home both domestically and in European fixtures. The club implements a loyalty points scheme offering the first opportunity to purchase away tickets to season ticket holders who have attended the most away matches. Everton often sell out the full allocation in away grounds and tickets sell particularly well for North West England away matches.
