Appreciate the trip report of IB and AB's TATL J product. Due to their former LCC heritage, one thing AB lacks is a solid lounge at their hub airports (DUS/TXL). Some people complain about AA's AC lounges, but it is certainly better than nothing. IB lounges are nicer, although they are just "business class lounges". Hopefully AB will build some decent lounges at DUS and BER.
