British Airways cabins have been put to the ultimate test as four reviewers took the same BA flight - but each person was in a different cabin.
While most of us are likely to only experience economy class when on a BA jet, the British flag carrier also offers premium economy, business class and first class.
A search on the company's site shows the cheapest London to Washington DC return flight in October is £467 in economy, £800 in premium economy, £3,501 in business class and £4,151 in first class.
