Seventh in the table and just six points off the last playoff spot, the Bluebirds are currently on a good run, having won their last three games.
In fact, they're now unbeaten in their last five league games, having lost the previous five, culminating in the sacking of manager Neil Harris.
Since taking over at the end of last month, Mick McCarthy, the current boss, has done a good job of steadying the ship. Meanwhile, consecutive wins against Bristol City, Rotherham United and Coventry City have breathed new life into the side.
They'll hope to continue with the same momentum against a Luton side languishing in the bottom half of the table.
The Hatters returned to winning ways last weekend against Birmingham City and also have a game in hand over Millwall, who are a point ahead of them.
