  There are some motivations to consider inflation driven by a phantom field.
Before entering into some specific models and perform data fitting, it is
important first investigating some general features that any viable inflation
model should hold. The inflationary attractor property is an important one of
those features. In this paper we will show that the inflationary attractor
property still holds for canonical and Born-Infeld phantom fields in the
standard Friedmann-Robertson-Walker cosmology, however, it does not hold for
canonical and Born-Infeld phantom fields in the Randall -Sundrum II cosmology.
