United Airlines is offering double miles on U.S. flights, though the offer comes with some strings attached.
The offer applies only to mainland U.S. flights booked between Oct. 21 and Nov. 21 for travel during the same period. The offer awards double redeemable miles, but does not double "qualifying" miles that count toward frequent-flier status.
Presumably not coincidentally, United's offer comes after low-cost giant Southwest rolled out its own double-points promotion for the same time period.
As for United's offer, it covers flights operated by United and those by regional partners that operate as United Express flights. The double-mile offer excludes flights to Alaska and Hawaii. For international trips, domestic segments will earn double miles - but the international legs will not.
To earn double miles, MileagePlus members must register (using code TB2M06) for the promotion and complete their travel between Oct. 21 and Nov. 21.
"This member-friendly promotion gives us another opportunity to reward our MileagePlus members for their commitment to flying with us," Praveen Sharma, United's VP of loyalty, says in a release. "It's a great opportunity for MileagePlus members to earn twice the miles during the busy fall travel season."
And, for those paying attention to the fine print, United's terms and conditions for offer say double miles will be awarded on most - but not all - paid fare classes. In its release, United says the following fare classes are included in the promotion: F, A, J, C, D, Z, P, Y, B, M, E, U, H, Q, V, W and S. That excludes some fare classes (T, L, K, G, N) -- fare types most-often associated with special or deeply-discounted fare types.
