Two Australian honeymooners took an earlier flight back from Europe but otherwise would have been on Malaysian Airlines flight MH17 which was shot down over Ukraine.
Simone La Posta and her husband Juan Jovel flew into Adelaide Airport this morning to news that there are no survivors from the flight they had originally been booked on.
"We flew into KL (Kuala Lumpur) via Amsterdam on the MH17 flight the day before," she said.
"We originally had our itinerary to be on that flight but then we changed it, thinking we'd be too jetlagged for work on Monday."
She says they found their earlier change of flight was overbooked so had to wait at the airport and literally found out at the last minute they had seats.
Our last photo on Facebook was a happy one of us on bikes out the front of a windmill and you sort of think how many other people would have had just innocent photos like that not knowing it was their last time?

"It's a bit surreal to think that one day later and I wouldn't be standing here," she said after passing through Adelaide customs.
"I think maybe I'll feel lucky eventually but I think right now you feel just very numb and maybe not so much lucky but more grateful to be here and not have been one of those poor people.
"We did the old Facebook update as we were sitting on the tarmac just to let people know that we were okay."
The couple has been busy since getting home responding to text messages and phone calls of concern from family and friends.
Ms La Posta says the concern from her own family and friends makes her realise how devastating the attack must be for family and friends of people who have died.
"Our last photo on Facebook was a happy one of us on bikes out the front of a windmill and you sort of think how many other people would have had just innocent photos like that not knowing it was their last time?" she said.
Mr Jovel echoed his wife's thoughts.
"It's surreal, just glad to be home," he said. "At the moment seeing all the images it's a bit hard to process it really."
He says his first thoughts were for Malaysia Airlines as it faced another aviation tragedy this year and for those on board, then he realised it was the same flight sector he and his wife had flown just a day before.
