Recent results from the NA48/2 and NA62 kaon decay-in-flight experiments at
CERN are presented. A precision measurement of the helicity-suppressed ratio RK
of the K+- to e+- nu and K+- to mu+- nu decay rates has been performed using
the full dedicated data set collected by the NA62 experiment (RK phase); the
result is in agreement with the Standard Model expectation. New measurements of
the K+- to pi+- gamma gamma decay at the NA48/2 and NA62 experiments provide
further tests of the Chiral Perturbation Theory. A planned measurement of the
branching ratio of the ultra-rare K+ to pi+ nu anti-nu decay at 10\% precision
is expected to represent a powerful test of the Standard Model.
