United R/T Award + free one way
I have a US - Asia trip that I have ticketed as one-way using miles. I wanted to book the R/T but due to lack of miles I was not able to do it. I recently understood the "free one way" on united awards.
I am planning to book the other one-way now (with miles) and wanted to utilize the free one way with UA. Not sure how to proceed.
Should I reserve the one-way & then call UA for combining these?
Will I have to cancel the one-way & then book the entire trip again?
Any other options?
