Substitutions on the Seattle route are not just limited to Lufthansa. Virgin Atlantic has been flying the route with the 787-9 but, as with a lot of the Rolls Dreamliner operators, Virgin has been suffering from engine shortages while the blade cracking problems are dealt with. They have brought the A340-600 on to the route in the interim. I thought I wouldn’t be seeing these again after the last examples at SFO I saw but I got another chance. Not great light but it was good to see one more time.
