HFD could be a mis-file as that’s a municipal airport unlikely to ever see intl ops. If MT were to ever start that area it would be BDL and even then an A330 is too big for the route, even if just 2-3 weekly.
ANC/FAI could be cruise related, however, DE have served FRA-FAI for some time so maybe they have seen an increase in pax from the U.K. and could start a MAN flight?
thanks for the update though.
