The incident, Ms Goyal said, occurred on Monday (November 13) when she was waiting for a connecting flight to Mumbai at the Munich airport.
"@lufthansa i am a #blind #traveller who was locked up in your #disability #assistance lounge at #munich #airport yesterday with no food no access to leave," Ms Goyal said in a series of tweets the next day.
"#humiliated #helpless, #forced, #denied i had to endure the next few hours till it ws time to board. unacceptable behaviour towards a #disabled #person."
Responding, Lufthansa said in a statement: "We are sorry to hear about Ms Goyal's encounter in Munich."
"At this point, we are investigating into the incident to ensure comprehensive understanding relating to all parties involved. We appreciate your understanding for the time being."
