We obtain new estimates for a class of oscillatory integral operators with folding canonical relations satisfying a curvature condition. The main lower bounds showing sharpness are proved using Kakeya set constructions. As a special case of the upper bounds we deduce optimalLp(𝕊2)→Lq(R𝕊2) estimates for the Fourier extension operator on large spheres in ℝ3, which are uniform in the radiusR. Two appendices are included, one concerning an application to Lorentz space bounds for averaging operators along curves in ℝ3, and one on bilinear estimates.
