  We study dimensional reductions of M-theory/type II strings down to 6D in the
presence of fluxes and spacetime filling branes and orientifold planes of
different types. We classify all inequivalent orientifold projections giving
rise to $\mathcal{N}=(1,1)$ supergravities in 6D and work out the embedding
tensor/fluxes dictionary for each of those. Finally we analyze the set of vacua
for the different classes of reductions and find an abundance of "no-scale"
type Minkowski vacua, as well as a few novel examples of (A)dS extrema.
