- 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 and then calculate the number of miles you will earn. 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. You will not earn PQD or award miles for the full amount of the displayed price for these itineraries because the U.S. Federal Transportation tax is not eligible to earn PQD or miles. Fare classes A, B, C, D, H, J, K, M, P, Q, S, T, U, V, W, Y and Z are eligible for accrual.
- The award miles accrued on codeshare flights are based on the operating carrier and their equivalent fare class. This could result in differences between the purchased booking class and the booking class flown, which determines the number of base and Premier qualifying miles and Premier qualifying segments earned.
- Ticket number starts with “016” and was purchased from United on united.com, through the United Customer Contact Center or at the airport, or from a travel agency or other travel website.
- Ticket number does not start with “016” and was purchased from an airline other than United or from a travel agency or other travel website.
- Flight distance is defined as the miles scheduled for a specific flight, as determined solely by United.
- All other fare classes do not accrue mileage. United and THAI reserve the right to change the eligible fare classes at any time without notice. Unless otherwise noted, Premier qualifying miles are based on flight distance, class of service and purchased fare class. Mileage accrual is subject to the rules of the United MileagePlus program and, as provided therein, mileage will be credited in accordance with the terms and conditions of the MileagePlus Program in effect at the time of travel, not at the time air travel is purchased, booked or reserved, and accordingly miles may not be awarded for some tickets or miles may be awarded in an amount fewer than shown. The award miles accrued on codeshare flights are based on the operating carrier and their equivalent fare class. This could result in differences between the purchased booking class and the booking class flown, which determines the number of base and Premier qualifying miles and Premier qualifying segments earned. MileagePlus award miles earned may vary depending on the Premier status of the customer.
- For more information on Premier qualification, including how to earn Premier qualifying dollars (PQD) on partner airlines, please see the Premier Status Qualification Requirements page.
- For Premier members who travel on eligible purchased fare classes on flights with a distance of less than 500 miles, 500 miles will be used as the flight distance for calculating the Premier qualifying miles earned, based on the percentages in the chart.
