French police are seeking her after Coulibaly and two other gunmen launched deadly attacks on Paris last week.
About 10,000 troops have been deployed in France following the attacks.
Hayat Boumeddiene has been identified as a suspect by French police, although she left France before the attacks.
The Turkish foreign minister said she arrived in Turkey on 2 January from Madrid, before continuing to Syria six days later.
The security footage, published by Haberturk newspaper, was released by Turkish police. It appeared to show Hayat Boumeddiene and a man at Sabiha Gokcen Airport in Istanbul.
Turkish officials told the BBC the man was Mehdi Sabri Belhouchine, a man of North African origin, and that he was not on a watch list. Officials believe he crossed into Syria with Hayat Boumeddiene.
French police had named Hayat Boumeddiene (L) and Amedy Coulibaly (R) as suspects after a policewoman was shot on Thursday
Hayat Boumeddiene's partner, Coulibaly, had killed four people
at a kosher supermarket in eastern Paris on Friday before police stormed
the building. He is also believed to have shot dead a policewoman the
day before.
Coulibaly had claimed that he co-ordinated his attack with brothers Said and Cherif Kouachi, who attacked the offices of satirical magazine Charlie Hebdo on Wednesday, killing 12 people. All three gunmen were shot dead on Friday after police ended two separate sieges.
French prosecutors said Hayat Boumeddiene had exchanged more than 500 phone calls with the wife of Cherif Kouachi in 2014.
French police said they had also found a second flat in Paris which had been used as a hide-out by Coulibaly, and contained weapons.
'Not Turkey's fault' Turkish Prime Minister Ahmet Davutoglu said on Monday that Turkey had not been asked to deny Hayat Boumeddiene access.
"We need to receive intelligence first so we can track people. We have 7,000 people on a no-entry list and deported 2,000, including French and German citizens."
He added: "Is it Turkey's fault that it has borders with Syria?"
2 Jan: Flew from Madrid to Istanbul,
accompanied by French citizen Mehdi Sabry Belhoucine. The pair attracted
the suspicions of Turkish authorities, who put them under surveillance.
They stayed at a hotel in the city for two days, where Boumeddiene is
reported to have bought a mobile phone and SIM card
4 Jan: Domestic flight to Sanliurfa near Syrian border. She is reported to have made a number of calls to France from Turkey. The pair did not use their return tickets to Madrid, dated 9 January
8 Jan: Crossed into Syria. On the same day, her partner Amedy Coulibaly shoots dead a policewoman, using Boumeddiene's car in the attack. The French authorities announce they are looking for her
10 Jan: Last recorded phone call, reportedly from the Syrian town of Tel Abyad - not far from the border
On Monday, France said it would deploy 10,000 troops to sensitive areas to boost security following the attacks.
It is the first time troops have been deployed within France on such a scale.
Defence Minister Jean-Yves Le Drian said the deployment, the first of its kind, was needed because "threats remain present".
Interior Minister Bernard Cazaneuve announced that nearly 5,000 members of the security forces would be sent to protect France's 717 Jewish schools.
Prime Minister Manuel Valls said synagogues would also be protected, as would mosques, following some retaliatory attacks over the Charlie Hebdo killings.
There had been more than 20 attacks on Islamic buildings and 30 threats against Muslims since Wednesday, a spokesman for the Central Council of Muslims in France said.
The four Jewish victims of the supermarket attack will buried at the Givat Shaul cemetery in Jerusalem on Tuesday.
On Sunday, an estimated 3.7 million people took to the streets to show solidarity with the victims, including 1.5 million people in Paris.
About 40 world leaders joined the start of the Paris march, linking arms in an act of solidarity.
Last week, Mr Valls admitted there had been "clear failings" after it emerged that the three gunman involved in the attacks had a history of extremism.
The Kouachi brothers were on UK and US terror watch lists and Coulibaly had previously been convicted for plotting to free a known militant from prison. Coulibaly met Cherif Kouachi while in jail.
Armed police patrolled on Monday in the Marais, a historic Jewish neighbourhood in central Paris
After the huge marches, a statue in Place de la Republique was left holding a giant "I am Charlie" pencil
The four men killed in Friday's supermarket attack will be buried in Jerusalem on Tuesday
Following the Charlie Hebdo attacks on 7 January, witnesses
said they heard the gunmen shouting "We have avenged the Prophet
Muhammad" and "God is Great" in Arabic ("Allahu Akbar").
On Monday, the magazine's lawyer said that the latest edition of the magazine, put together by surviving staff, would feature caricatures of the Prophet Muhammad, along with other figures.
The magazine would "cede nothing" to extremists, Richard Malka told French radio.
It will have a print run of one million copies, compared with its usual 60,000 a week.
The satirical weekly has courted controversy in the past with its irreverent take on news and current affairs. It was firebombed in November 2011 a day after it carried a caricature of the Prophet Muhammad.
