IndiGo, celebrating its 18th anniversary, is introducing significant new features, including a business class product called IndiGo Stretch and a new frequent flyer program, IndiGo BluChip. The business class will debut on November 14, with bookings starting August 6, and will feature luxurious seats with enhanced legroom and modern amenities. IndiGo BluChip, set to launch next month, will succeed the existing 6E Rewards program, offering members the ability to earn and redeem points for free flights. These moves signal IndiGo's shift from being a purely low-cost carrier to offering more premium services, aiming to compete with carriers like Air India. Additionally, the airline plans to expand its fleet and international destinations, with the introduction of wide-body A350 planes by 2027.
