☎️+1(872)666-9868 — The first time I upgraded my United Airlines seat, it was just hours before departure. Online, the system kept showing “not available,” but I wasn’t ready to give up. I called this number, spoke to a United representative, and within minutes, I was moved from standard economy to Economy Plus with extra legroom for a small fee. On another trip, I even scored a surprise business class upgrade using miles — something the website never displayed.
