A British Airways stewardess smashed a glass into the face of her pilot lover when he told her their affair was over.

Senior British Airways cabin crew member Frances Smith, 36, flew into a rage when the divorced pilot ended their 18-month relationship, smashing a wine glass as they were out drinking near Cardiff Airport, a court heard.

She then drove the jagged glass into his face leaving him with a three-inch deep wound to his jaw which needed internal and external stitches.

She ran from the scene but was detained by an off-duty officer and later confessed to police: “I did it, I’m really sorry, I’ve done a stupid thing.”

The pair, who had been in a relationship for 18 months, had been drinking near Cardiff Airport when they began arguing, the Sun reported.

Prosecutor David Pugh said: “There were then text messages between them and he said, ‘Leave me alone, we’re finished’. She struck him with a broken glass to his face.”

He suffered an 8cm cut to the side of his jaw, which required deep and surface stitches.

Smith, of Troon, Ayrshire, who used to work as a waitress in a strip club before getting a job with BA, admitted wounding and was sentenced to a year in jail suspended for two years.

Judge Tom Crowther QC noted: “Had that injury been lower, the consequences would have been utterly dreadful.”

She was also ordered to pay costs of £535 and a victim surcharge of £100.

A BA spokesman said she no longer works for the company.
