The woman has criticized the company on social media for the alleged substandard food during the Indigo flight. Delhi-based dietitian Khushboo Gupta posted an Instagram video showing a live worm found in a vegetarian sandwich she bought during her IndiGo flight from Delhi to Mumbai on the morning of December 29. When Gupta informed the Indigo flight attendant about the insect, his allegedly rude response was even more distressing. The company said that it is investigating the matter and apologizes for the incident.
