The Town Ticket Office would like to remind supporters that Saturday's fixture away at Southend United is an all-ticket game.
The Hatters currently have just over 200 tickets left from the full allocation of 2,000 seats.
Tickets remain on sale from the Ticket Office by phone or in person or also available online.
Tickets purchased by 3pm tomorrow (Tuesday) can be posted.
Any tickets ordered after this need to be collected from the Luton Town Ticket Office or arrangements made to collect on the day at Southend.
