Appellants appeal the district court’s denial of their motion for conditional class certification pursuant to § 216(b) of the Fair Labor Standards Act. Appellees contend that we do not have jurisdiction to hear the appeal.

This Court’s jurisdiction is limited to appeals from final decisions under 28 U.S.C. § 1291, interlocutory decisions under 28 U.S.C. § 1292, non-final judgments certified as final under Federal Rule of Civil Procedure 54(b), and other non-final orders or judgments to which an exception applies. Clark v. Johnson, 278 F.3d 459, 460 (5th Cir. 2002). The denial of a § 216(b) class certification is not a final decision under § 1291, nor does it fall under the “collateral order” exception to § 1291’s final judgment rule. See Baldridge v. SBC Commc’ns, Inc., 404 F.3d 930, 931, 933 (5th Cir. 2005). Further, absent certification under § 1292(b), it is not an interlocutory decision over which we have jurisdiction. See § 1292(a). The district court did not certify its decision as final under Rule 54(b), and there is no other exception that applies to give us *4 jurisdiction. Accordingly, the appeal is DISMISSED for want of jurisdiction.
