Seems that someone at Delta is not aware of that they have not been able to secure used Airbus A380’s (at least not yet). Delta is known to buy old planes from other airlines.
Delta or their advertising agency here in Japan is using Airbus A380 looking aircraft in Delta’s livery advertising their flights from Japan to Guam and Hawaii.
I just saw this ad this morning on some shuttle bus used in/around Narita airport in Japan.
This is quite a mistake by someone at Delta that must have signed off the ad being used here. They could have easily used Boeing 747 instead of this Airbus A380 looking aircraft.
