Passenger is asked to move seats because he has a prosthetic leg

This is the shocking moment airline staff told a disabled passenger that he would have to move seats unless he could 'run and jump to prove his prosthetic leg was able to support him.
Tim Seward, 31, was flying from Beijing, China, to Seoul in South Korea with Asiana Airlines when he was approached by a cabin crew member who said: 'I cannot prove if your leg is functional.'
The industrial designer, who had his limb amputated at the age of 11 because of cancer, had paid extra money for an exit row seat which requires passengers to be physically able to open the emergency door in the event of a crash landing.
Although Tim has a prosthetic leg he told MailOnline that he is 'more capable than most people physically' and even managed a career as a professional skater during his 20s.
After boarding, he had asked the steward: 'So the company told you to move a disabled person because in this seat according to your policy you do not allow a disabled person to sit in this seat because I wear a prosthetic leg?'
After the staff member ordered him to move he asked to speak to the cabin manager.
But according to Tim the man then came back with three security guards who escorted him to another seat.
Tim, who was visiting China alone from his home in San Francisco, California, US, told MailOnline: 'It caught me off-guard completely.
'Even with everything that's happening on flights these days I couldn't believe what happened and that I am the one having to deal with it.'
MailOnline has attempted to contact Asiana Airlines for comment.
