After a short presentation of the FLAG collaboration, we review lattice results related to pion, K-, D- and B-meson physics with the aim of making them easily accessible to the particle-physics community. Only a selection of FLAG averages or estimates is presented. For light flavours, we present results on the form factor f+(0), arising in semileptonic K → π transition at zero momentum transfer, as well as the decay-constants fK,fπ and their ratio. The consequences of these results for the CKM matrix elements |Vus| and |Vud| are discussed. For heavy flavours we focus on D- and B-meson decay constants and form factors, as well as the CKM matrix elements |Vcs|, |Vcd| and |Vub|. In addition we briefly cover the recent advances stemming from the calculation the BK-parameters and touch upon related current results relevant to the Physics beyond the Standard Model, which will be the subject of the next FLAG edition.
