United is offering double miles for flights within the 48 Continental United States (so excludes Alaska and Hawaii) for tickets purchased and travel between October 21 and November 21.
Registration is required, tickets purchased prior to the promo period are excluded, and while most paid fares are eligible (“F, A, J, C, D, Z, P, Y, B, M, E, U, H, Q, V, W and S”) the cheapest fares are not.
It’s a good offer if you have to buy tickets still for travel within the next month, but I hate that they exclude tickets you already may have bought.
The offer is not for double elite qualifying miles, and codeshare and partner flights aren’t eligible.
