We study approximate Birkhoff–James orthogonality of bounded linear operators defined between normed linear spaces $$\mathbb {X}$$X and $$\mathbb {Y}.$$Y. As an application of the results obtained, we characterize smoothness of a bounded linear operator T under the condition that $$\mathbb {K}(\mathbb {X},\mathbb {Y}),$$K(X,Y), the space of compact linear operators is an M-ideal in $$\mathbb {L}(\mathbb {X},\mathbb {Y}),$$L(X,Y), the space of bounded linear operators.
