Cons: Korean airlines ignored my wife's request for a wheel chair. She explained that she was a diabetic and was feeling dizzy. They did allow her access to a short cut through the terminals; however she had collapsed, broke her watch, cover to the cell phone, injured both legs and right arm. She kept yelling for help and no one arrived, she managed while in intense pain to get up make her flight. When she arrived in Bangkok she went immediately to the Emergency Room and received treatment.
I am appalled at the indifference of the members of the boarding crew that didn't offer assistance to my wife.
