I'm trying to find the baggage allowance for the following itin:
IT 7079 29Sep LIS->LHR (operated by British Airways)
IT 2 29Sep LHR->DEL
IT 3214 29Sep DEL->BLR


From Kingfishers website I gather that LHR->DEL allows 2 pieces of 23kg bags.
DEL->BLR is only one piece at 20kg.

British Airways only allows 1 bag of 23kg inside europe (but two 23kg bags
if travelling to India).

Since the itin has multiple segments; I want to know the baggage allowance.
Can I carry two 23kg bags from LHR->DEL->BLR or will I have to pay extra?
for DEL->BLR?
What about LIS ->LHR?

Also, what are the excess baggage charges for this itin?

Thanks.
