Last year my family members and I each traveled about just under 21000 miles (into and out of the US) with United Airlines, but neither of us created an account or anything when booking these flights. Was just wondering whether myself or my family are now eligible for any discounts or anything that could potentially get us lower prices on United if we were to fly them again this year.
I suspect there may be mileage programs, but even if there is one I'm really unsure as to how they fully work as I've never really taken part in one before. Many thanks.
