State-owned carrier Air India has put on sale nine of its 21 Dreamliners (B787-800) to raise over Rs 7,000 crore to fund acquisition of new aircraft and also for repayment of the bridge loan availed earlier for purchasing these Boeing 787-800s. Also, Air India will offer free return-tickets under a web loyalty scheme on purchase of six business class or ten economy class one-way tickets through the airline's website. The sales and travel validity of the scheme is from next Thursday to December 15.
