$7000
Did I miss a memo or something? I'm trying to book two trips to Germany in April and October and normally there is a nice linear fare increase from Main, C+, Premium and D1 but (at least at the moment) the lower fares are on par with what is expected but D1 is between 3-5x higher than Premium. All of the outbound D1 fares are >$6600 but the return fares drop to the more typical ~$4000. Why the premium to get in to Europe this summer?
