For this promotion, only dollars spent on the "fare" on eligible flights operated by United® and United Express® will qualify toward meeting spending milestones. Certain specialty tickets, including but not limited to unpublished, consolidator/bulk, group, tour and opaque fares, will not be counted towards spending milestones. Dollars spent on tickets purchased for flights operated by Star Alliance™ member airline or a United MileagePlus® partner airline with tickets issued by United (ticket number starting with "016") will not qualify for this offer. The "fare" is the base fare of the ticket plus carrier-imposed surcharges, excluding any government-imposed taxes and surcharges. For tickets purchased in a currency other than U.S. dollars, we will convert the purchase to U.S. dollars using an industry standard exchange rate. Please note that the price displayed when purchasing a ticket on united.com includes up to a 7.5% U.S. Federal Transportation Tax on the base amount of the fare on itineraries wholly within the United States. This tax also applies to certain itineraries between the United States and Canada or Mexico.
