Doing JFK-VIE then VIE-NRT in C in about two weeks. Will report back. Will also be doing LH from NRT-FRA on same trip.
Bear in mind I just enjoyed LX F NRT-ZRH-NRT a couple weeks ago.
Should be fun comparison shopping.
Remind me if I fail to get a post up by Sept 1. Flying mid to end Aug.
Looking forward to the feedback!
