1.) Aeroflot : This is the cheapest one. But it is only from Delhi. It is offering 23kg checked + 23kg checked + 10kg cabin + 1 laptop bag. I would suggest checking their website once before booking from any makemytrip or cleartrip website as they could be charging more than the Airline website. Roughly, it will come out to be 23kg.

2.) British Airways : They have come up again with the student offer of 23kg checked + 23kg checked + 23kg cabin + 1 laptop bag. The fare would come something around 32 to 35k depending on the city. But the only thing is you will have to get the transit visa for Heath-row Airport.
Offer: 23Kg + 23Kg Check-In Luggage, 23Kg Cabin Luggage (including laptop bag)
Flight can be booked online . After booking one needs to call and inform them and while boarding student visa needs to be shown. (Called their customer care and confirmed.)
Prices are on a higher side compared to other carriers but offer beats them all.
No transit visa required if connecting flights are from same airport.
