Arsenal booked their place at Wembley as they finally broke down Ipswich to win 3-0 in the Carling Cup semi-final second leg at the Emirates Stadium.
The npower Championship club were protecting a slender 1-0 lead from a fortnight ago in Suffolk, and defended resolutely to frustrate the Gunners for more than an hour.
However, Nicklas Bendtner finally ended their resistance with a fine individual goal.
A quick ball from Jack Wilshere out to the left was brought down superbly by the Dane, who then cut inside with a deft backheel before curling a low shot into the bottom right corner.
Laurent Koscielny headed in a second when Marton Fulop came to punch a left-wing corner from Andrey Arshavin but got nowhere near the ball and the defender headed in from six yards.
And captain Cesc Fabregas kept Arsene Wenger's men on course for a first trophy since 2005 when he slotted home after being played in by Arshavin following a surging 40-yard run.
