I am arriving in a week's time, BA from Heathrow - Haneda - Itami on same ticket, both operated by BA. Transit time is 2 hours (arrival Haneda morning 7ish). I am reading different messages and got a bit confused.

My question: is it correct that baggages cannot be put through from London to Itami? I need to be claimed at Haneda, through immigration/security again for domestic flight? Any idea how long the baggage claim could take at current time?

For my return flight Itami - Haneda - Heathrow, it is operate by JAL and BA and transit time is only 90mins at Haneda.

Question 2: will I be able to check baggages through to London from Itami? is 90mins too tight given just over MCT?

Thanks all.
