I've got a different question, about baggage on IndiGo domestic flights. IndiGo online says the allowance is 15 kg, but it also says "For Double or MultiSeats bookings, extra 10 kg." I don't understand what that means. I'm not even sure what the terms mean - can anyone clarify what they are and what the difference is?

I'll be flying with my wife - is that a double booking? A multiseat booking? Does that mean we'd each get a 25 kg allowance as a "reward" for being a double or multiseat booking. Or that the first person gets a 15 kg allowance and the second person only 10kg? Or what?

While I'm at it, does anyone know what the cost for extra kg is on short flights (COK-HYD, HYD-BOM?). On their baggage page I see the rules for domestic bags (though confused by them) but not the costs for being over them.

Hoping someone can clarify. Thanks!
