Hi

I have booked my flight through edreams.de/

I am traveling with my wife and six month old my son


edreams have booked my flight

We are 2 Adult + 1 Infant traveling together.

from Hamburg to London it is British airways
and from London to Delhi it is Kingfisher airline.

If i check on both airlines website both have different baggage allowance for checked baggage and handbaggage.

British airways has checked baggage 23 kg for each passenger including 1pc _ + infant stroller for an infant.
and hand baggage for each passenger including 1pc infant. + 1 laptop

where as Kingfisher has 23 X 2 pc for each kg and 10 kg for adults + 1 infant stroller for infant.
and hand baggage only 7 kg per adult.

1st Question: Which baggage allowance is applicable for me? Kingfisher's or British airways it? " I can not pack according to two different airlines (neither can I pack unpack at London airport)

2nd question: I am Indian Citizen and living in Germany on resident permit. have around seven hours stay at London airport terminal including change I from Terminal 5 to Terminal 4
Do I need transit visa for London, UK airport?
