Days later, the story - and the potential consequences for the man in question - have spread internationally.
Today Barcelona Deputy Mayor Jaume Asens condemned Ryanair's response as "unacceptable" and vowed that Barcelona City Hall officials would report it to Spanish prosecutors.
In subsequent tweets, Asens asked for witnesses to come forward and said Barcelona is a welcoming and inclusive city that would not tolerate such an assault.
Spanish police involvement comes after Ryanair said it had reported the matter to Essex police in the United Kingdom.
Essex police confirmed that they had identified "both parties involved" and passed that information on to Spanish authorities, who would be leading the investigation.
"Our officers will continue to provide assistance where necessary throughout the course of this case," Essex police stated.
Ryanair has said it cannot comment further "as this is now a police matter."
It's unclear what this sudden flurry of police activity could lead to in terms of consequences for the male passenger. The man was not immediately reported to police after the plane landed at London Stansted Airport and, as Lawrence told the Washington Post, appeared to be allowed to go on his way without being questioned.
According to the newspaper El Pais, Spain's Public Works Ministry will also investigate whether Ryanair should have disciplined the man as "a conflictive passenger" under current Spanish law.
For Gayle, the man's rant has already done its damage. She and her daughter had been returning from a holiday to Costa Brava in Spain to mark the anniversary of the death of Gayle's husband - a trip that was intended to cheer her mother up, Gayle's daughter told ITV.
Instead, Gayle said she felt shocked and depressed and was having trouble sleeping after the incident.
"I feel very low," the 77-year-old retiree told the British network. "He paid fare to go on holiday, and I paid mine. So why does he abuse me due to the colour of my skin?"
Gayle said she thought Ryanair's handling of the confrontation was unprofessional and that they needed more training.
"He do it with me and he gets away, he'll do it to somebody else," she added.
