Hey everyone!

Was looking at booking this great deal I found for a one way business class flight from Newcastle to Los Angeles on British Airways and airBerlin. I'd be flying economy on British Airways NCL-LHR-BER, then BER-LAX on airBerling the following morning in business class. It's all on the same ticket so I wanted to see what will my baggage allowance be considered as? The difference airlines, different classes and different baggage allowances of the airlines has me thrown.

Many thanks in advance!
