Two YouTube pranksters were thrown off a Delta Airlines flight at Heathrow on Wednesday.
Adam Saleh, who was with his friend Slim, claims they were asked to leave after he on the phone to his mother in Arabic.
While there has been much debate over the veracity of their story, owing to their history of outlandish and misleading viral videos, Delta says it is taking allegations of discrimination "very seriously".
Even if their account is disputed, there is a long and inglorious history of Muslim people being thrown off flights for spurious reasons.
Here are examples from this year alone:
1. 4 August 2016
Two Muslim women were escorted off an American Airlines flight by armed police in August after a flight attendant said they made him feel "unsafe".
One of the women, Niala Mohammad (pictured above), said that their plane had been grounded for about five hours in Miami and they were not allowed to buy food or drink. After making complaints they were told to get off.

A Muslim woman was asked to get off a plane at Chicago airport in April without any explanation after she asked her neighbour to switch seats.
The Council on American Islamic Relations (CAIR) has called for an investigation of a possible “bias motive” as the woman was of Somali descent and was wearing a headscarf.
When police asked the flight attendant at the gate if there was any reason why the woman had been taken off the plane, the flight attendant replied “no” and that she did “not feel comfortable” with the passenger.

Syed Adam Ahmed, a six-year-old boy from Canada, has been repeatedly banned from boarding flights because he is on a "high risk traveller" list.
Despite authorities promising to remove him from the list months earlier, Syed was banned from boarding an Air Canada flight in March.
Although they have had no explanation for why their son is on the list, his family believe it may be because he shares his name with a suspected terrorist.
4. 17 April 2016
A man who moved to the US as an Iraqi refugee was removed from a Southwest Airlines flight in April after making a call to family in Baghdad.
After telling his uncle about the chicken dinner he'd had at an evening with UN secretary general Ban Ki-moon, Khairuldeen Makhzoomi was asked to disembark the plane because his conversation had "alarmed" another passenger who accused him of making "potentially threatening comments".
5. 1 April 2016
A family of five were kicked off a United Airlines plane at a Chicago airport just before take-off in April with staff citing "safety concerns" but not providing a full explanation.
Eaman-Amy Saad Shebley (pictured above), who was with her husband and three children, asked the pilot whether it was a “discriminatory” decision. The pilot replied it was a “flight safety issue” but did not give any further details.
6. 20 July 2016
A Muslim man was removed from an American Airlines flight last month after a flight attendant publicly announced his name, seat number and said she would be “watching” him.
Mohamed Ahmed Radwan had boarded a plane in Charlotte, North Carolina and the flight attendant went to the tannoy and said: “Mohamed Ahmed, Seat 25-A: I will be watching you.”
The employee made no other announcements about any other passenger.
7. 4 August 2016
A Muslim couple accused Delta Airlines of Islamophobia for throwing them off a flight from Paris to Cincinnati.
