  We consider a class of helical phase inflation models from the ${\mathcal
N}=1$ supergravity where the phase component of a complex field acts as an
inflaton. This class of models avoids the eta problem in supergravity inflation
due to the phase monodromy of the superpotential. We study the inflationary
predictions of this class of models in the context of both standard and large
extra dimensional brane cosmology, and find that they can easily accommodate
the Planck 2018 and BICEP2 constraints. We find that the helical phase
inflation has $\alpha$-attractors and the attractors depend on one model
parameter only.
