We compute the Newton–Okounkov bodies of line bundles on the complete ag variety of GLn for a geometric valuation coming from a ag of translated Schubert subvarieties. The Schubert subvarieties correspond to the terminal subwords in the decomposition (s1)(s2s1)(s3s2s1)(⋯)(sn–1⋯s1) of the longest element in the Weyl group. The resulting Newton–Okounkov bodies coincide with the Feigin–Fourier–Littelmann–Vinberg polytopes in type A.
