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.
*Premier members earn a minimum of 500 base miles on all eligible purchased fare classes
** G, V, W fare classes only eligible for accrual on flights within Thailand
