All-American Rejects, Hawthorne Heights, From First To Last and an as-yet-unnamed Decaydance Records act will support on the trek, which is to include a whopping 46 arenas across North America.

The tour starts March 15 at Albany, N.Y.’s Pepsi Arena and wraps May 13 at Ricoh Coliseum in Toronto.

Fall Out Boy’s platinum-certified major-label debut, From Under The Cork Tree, earned the group a best new artist nomination for the upcoming Grammy Awards.

Last year, the band started out with a two-month headlining club run, then wowed the crowds on the Vans Warped Tour before topping the Nintendo Fusion Tour bill.
