Jacques Ibert ( works for oboe, flute), Henri Tomasi, Honegger ( a lovely "Concerto da camera" for English horn & flute), Frank Martin ( Ballade for flute & chamber orch.). Dutch composer Hendrik Andriessen's Variations on a theme by Couperin ( flute & strings) is gorgeous - and so is Gunnar de Frumerie's Pastoral suite ( flute, harp strings) . Hamilton Harty's "In Ireland" ( flute,harp,orch.) is another little ,tuneful gem - not to be missed! ( check Naxos).
