Bukayo Saka put the Gunners ahead from the penalty spot in a one-sided first half before Leandro Trossard swept home their second following a spell of Bournemouth pressure after the break.
The visitors had a goal controversially ruled out after that, with VAR upholding referee David Coote’s decision to penalise Dominic Solanke for a foul on David Raya, before Declan Rice added a stoppage-time third to put the result beyond doubt.
The victory, Arsenal’s fourth in a row, maintains their title charge and puts the pressure back on Manchester City as they host Wolves
