UPDATE 27 DECEMBER 19:00 CET: All tickets in the second wave have been sold.
The original story follows below.
In total there will be four waves of ticket sales for the 2018 Eurovision Song Contest. Tickets for the remaining shows, including the Semi-Finals, will be on sale in further waves in January 2018 after the Semi-Final Allocation Draw.
BlueTicket, the official ticketing partner for the 2018 Eurovision Song Contest, operates a system called Queue-It, which is used to sell tickets for many of the biggest events in the world. It prevents the site from crashing if all users accessed the queue for the ticket selling platform simultaneously.
Those who arrive in the queue for tickets before the sale opens are assigned a random number at the time of the opening of the sale. This means that no one is at an advantage when they arrive on the ticket purchasing page just before the sale starts. Users who join the queue after the sale starts are then assigned a sequential number behind those who joined it beforehand.
It is strongly recommended that tickets are purchased through the official ticketing partner.
