Had the same experience. Side note, taking pseudoephedrine HCl has been an absolute lifesaver for me when I have terrible sinus pressure on planes. If you Google for "relieve sinus pressure on plane" or something similar, most of it is stuff that won't help when you're already in pain. I always take an ibuprofin and the real deal sudafed to open up my sinuses and relieve the pain, it works pretty well.
