A Qatar Airways flight had to make an emergency landing after a female passenger found out her husband was cheating on her mid-flight, reports the Hindustan Times.

The unidentified Iranian woman reportedly used her husband’s fingerprint to unlock his phone while he was asleep, before becoming incensed by what she found on the device.

Flight attendants were unable to calm the woman as she repeatedly hit her husband, causing the pilots to make the decision to make an emergency landing in India on 5 November.

The flight was on its way from Doha to Bali when the incident took place, forcing the plane to land in India so that the couple and their child could be removed from the plane.

"The family spent the day at Chennai airport. No police action was taken," an unnamed source told the Hindustan Times.

Local Chennai paper the New Indian Express, meanwhile, reported that airport director G Chandramouli claimed the woman was drunk and said the family were not allowed to board a subsequent flight until she had sobered up.

This comes after The Independent reported on a pair of strangers who were caught having sex on a Delta Air Lines flight from Los Angeles to Detroit.

The woman, 48, was arrested while on the plane for performing oral sex on the man, 28, police told WDIV-Local 4 in Detroit.

Both parties could face charges of misdemeanour or felony, and both were issued citations according to FBI officials, who say the investigation is still ongoing.
