This one has probably been around before, but I think it is awesome done by BA (true or not)

--------------------

On a British Airways flight from Johannesburg, a middle-aged,
well-off white South African lady has found herself sitting next
to a black man. She called the cabin crew attendant over to
complain about her seating.

"What seems to be the problem, Madam?" asked the
attendant.

"Can't you see?" she said, "You've sat me next to a kafir. I
can't possibly sit next to this disgusting human. Find me
another seat!"

"Please calm down, Madam." the stewardess replied. "The
flight is very full today, but I'll tell you what I'll do. I'll
go and check to see if we have any seats available in club or
first class".

The woman cocks a snooty look at the outraged black man
beside her (not to mention many of the surrounding
passengers). A few minutes later the stewardess returns with
the good news, which she delivers to the lady, who cannot help
but look at the people around her with a smug and
self-satisfied grin.

"Madam, unfortunately, as I suspected, economy is full. I've
spoken to the cabin services director, and club is also full.
However, we do have one seat in first class".

Before the lady has a chance to answer, the stewardess
continues: "It is most extraordinary to make this kind of
upgrade, however, and I have had to get special permission
from the captain. But, given the circumstances, the captain felt
that it was outrageous that someone should be forced to sit
next such an obnoxious person."

With that, she turned to the black man and said: "So if you'd
like to get your things, sir, I have your seat ready for you..."

At which point, the surrounding passengers stood and gave a
standing ovation while the man walked to the front of the
plane . . .
