New Delhi, April 7 (PTI): Trinamul Congress lawmaker Dola Sen allegedly delayed Air India's Delhi-Calcutta flight on Friday by nearly 40 minutes after an argument over seating arrangement.

Dola had booked her seats via makemytrip, paying extra, said Air India.

When Dola boarded the plane with her wheelchair-bound mother, the cabin crew told her that rules do not permit wheelchair-bound passengers to sit in emergency exit seats, said Air India.

The airline said the MP didn't mention that a wheelchair-bound passenger was accompanying her at the time of booking tickets.

The lawmaker “shouted and screamed” at the cabin crew, the airline claimed.

This forced the pilot to come out of the cockpit, and offer business class seats to Dola’s mother but she declined.

Dola could not be immediately reached for comments.
