For those who wonder if the small Airbus can make it, Lufthansa use them on similar business-only services from Dusseldorf to Newark and Chicago, a good deal further
BA will operate the A318, Lufthansa operated the A319 in the past from DUS. Hence also my question if the 32seat layout is a result of performance restrictions given that Lufthansa put 48seats in the only slightly larger A319.
