Indonesian Louise Sidharta, 25, was supposed to meet up with her fiance and his five family members in Singapore.
The seven of them were travelling from Surabaya to Singapore for a holiday.
Despite taking a later flight, she arrived at Changi Airport from Surabaya before them.
Mr Alain Oktavianus Siauw, 27, his parents, and three brothers were on the ill-fated AirAsia Flight QZ8501.
Miss Sidharta told reporters at Changi Airport on Sunday that she and Mr Alain had planned to marry in May next year.
Their trip here was supposed to be their last vacation together before getting hitched, she said in a mix of English and Bahasa Indonesia.
She said she was on the way to the airport in Surabaya when she heard the news that Flight QZ8501 had gone missing.
"I heard it on the radio and immediately browsed the Internet and saw the news. My heart knew by then that my fiance was on that flight," she said.
