A ticket mix-up left a man stuck at the airport in Iran while his wife boarded the doomed Ukrainian International Airline flight believed to have been shot down by an Iranian anti-aircraft missile system.

When Mohsen Ahmadipour said goodbye to his wife Roja Azadian, he had no idea it would be their last.

The couple had been visiting their families before they prepared to return home to Ottawa, Canada.

But when they arrived at the airport in Tehran, Ahmadipour was told that his ticket was no longer valid, according to the Ottawa Citizen.

The pair had planned to return home together, but instead Ahmadipour told his wife that he would join her in Canada as soon as he could get on another flight home.

Azadian, 43, boarded the flight while Ahmadipour stayed at the airport. The flight took off. And within moments she was gone.

Flight PS752 came down just minutes after leaving the runway at Imam Khomeini International Airport. Fifteen children, including a baby born in 2018, were named among the dead which comprised of 82 Iranians, 63 Canadians, 11 Ukrainians, 10 Swedes, four Afghans, three Germans and three Britons.

Ahmadipour learned of the crash from inside the terminal.

'He was the lucky person who didn’t get on the plane,' Kevin Manesh, a veterinarian and public relations director of the Iranian Arts and Cultural Society of Ottawa, told the Ottawa Citizen. Manesh explained that Ahmadipour had canceled a portion of his trip, assuming that the flight between Tehran and Toronto was still valid.

The grieving husband's wife was among the 63 Canadians who lost their lives in the horrific crash.

He said most of victims were visiting family in Iran over the holidays. He said many were dual citizens and many were international students.

'One of the reasons why you take that flight is you wouldn't want to take a flight that has a connection in the United States because international students can't do that,' he said.

The Iranian regime has insisted the plane's engine caught fire causing a loss of control, but has fueled suspicion of foul-play by refusing to hand over the craft's black boxes.

Video footage appeared to show the plane already burning before it fell out of the night sky, while pictures at the crash site showed the mangled wreckage peppered with mysterious holes.

The Boeing plane was less than four years old and had been checked just two days earlier, with 'one of our best crews' manning the aircraft, the Ukrainian airline said.

On Thursday it was revealed that US officials are 'confident' that Iran shot down the Boeing 737-800 jet after detecting a radar system being turned on before two missiles were launched, shortly before an explosion believed to have come from the jet.

Two Pentagon officials added that the missiles were likely launched in error by Iranian anti-aircraft crews awaiting a US response to Iran's rocket strikes against American bases in Iraq, according to Newsweek.

If true, the incident would be hugely embarrassing for Iran which had sought to avoid killing anybody in Wednesday's strikes, especially since 82 of the plane's passengers were Iranians.

It could also spark fresh tensions in the Middle East just a day after Trump said Iran seemed to be 'standing down'.

The jet which crashed was a Boeing 737-800 - a very common single-aisle, twin-engine jetliner used for short to medium-range flights. Thousands of the planes are used by airlines around the world.

Introduced in the late 1990s, it is an older model than the Boeing 737 MAX, which has been grounded for nearly 10 months following the two deadly crashes in Indonesia and Ethiopia.

According to flight tracking data from FlightRadar24, the jet reached an altitude of 7,925ft before tracking suddenly ended after three minutes.

The plane had been delayed from taking off from Imam Khomeini International Airport in Tehran by almost an hour.

'The plane was in working order,' UIA company president Yevgeniy Dykhne told a briefing in Kyiv where he choked back tears.

'It was one of our best planes with a wonderful crew.' It was the Kyiv-based carrier's first fatal accident.

Just hours before the crash, the US Federal Aviation Administration had banned US airlines from flying over Iran, Iraq and the waters of the Persian Gulf due to the Middle East crisis.
