Business Selling Class: I
I want to book Qatar business class through BA. The BA site only offers me "Business Selling Class: I" which, I assume, is equivalent to Qatar's 'Classic', which does not include lounge access and advance seat selection. Am I able to book Qatar 'Comfort', which does include lounge access and advance sat selection, through BA? If so, how do I go about it? If not, can I contact Qatar and pay for the change? If so, will the cost be the difference between their 'Classic' and 'Comfort' fares? TIA.
