New Delhi: Passengers of no-frills carrier IndiGo will have to shell out up to 800 extra if they opt for web check-in, as the airline has revised its policy.

“As per our revised policy all seats are chargeable for web check-in. Alternatively you may check-in at the airport for free. Seats will be assigned as per the availability," IndiGo said in a series of tweets Sunday.

The Gurugram-headquartered airline reported its first quarterly loss at 651 crore in July-September period amid high fuel cost and rupee depreciation.

Meanwhile, the Ministry of Civil Aviation has said that it is reviewing charges levied by airlines for web check-ins for all seats. “MoCA has noted that airlines are now charging for web check-in for all seats. We are reviewing these fees to see whether they fall within the unbundled pricing framework," the ministry said in a tweet.

The revised policy is effective from November 14, it said.

Accordingly, IndiGo will charge between 100-800 for such selection online, depending upon the position of the seat.

For web check-in of a first-row seat, a passenger will have to pay as much as 800 extra, while a non-reclining seat in row 12, which is next to the emergency exit, will cost an additional 600 when selected online.

A middle seat in the last row will cost 100 more, as per the revised charges.

Earlier, the budget carrier charged only for particular types of seats like a window or aisle seat or seat having extra legroom when passenger opted for online selection.
