England's Chris and Gabby Adcock reached the Thailand Open final with a three-game victory over the third seeds from Chinese Taipei.
The Adcocks - the top seeds - defeated Wang Chi-lin and Lee Chia-hsin 21-16 19-21 21-7.
They will face Indonesian eighth seeds Hafiz Faizal and Gloria Emanuelle Widjaja in Sunday's mixed doubles final in Bangkok.
Faizal and Widjaja beat England's Ben Lane and Jess Pugh in the second round.
Victory on Sunday for the Adcocks - the reigning European and Commonwealth champions - would mark England's first success at the Thailand Open since 2004, when Olympic silver medallists Nathan Robertson and Gail Emms won the title.
