he government is reviewing a move by private airlines IndiGo and SpiceJet to charge for seats booked in advance through the web check-in feature, which has provoked anger among air-travelers. The Civil Aviation Ministry tweeted it had noted that airlines are now charging for web check-ins for all seats. "We are reviewing these fees to see whether they fall within the unbundled pricing network," said the tweet. Unbundled pricing allows passengers to pay for exactly what they want instead of expensive tickets.
