Per-booking a meal is not a guarantee for Indigo
I booked a sandwich and beverage (CJSW) on MAA-CCU today, but all I received was a “Sorry, your pre-booked item is not available. Would you like a tea or coffee?” Indigo seems to be trying to discourage per-booking meals and scare away corporate travellers.
*Pre book
Update: After giving a very bad review on the trip feedback, Indigo contacted me over telephone and offered either a refund or the same meal on my next flight (they sent an email and said it would be done if I replied with the new PNR).
