Since I know that Christina will soon be posting to her newly created travel blog (I'll link to it when it goes live), I'll save the details of the trip for her to report. Instead I'll concentrate on the minutiae of travel that consume me...like what airline we ended up on.
For some reason, I could only get Christina a free ticket to Switzerland on Lufthansa. I am restricted to booking American (the nationality, not the brand) airlines, but I was able to book the flight on the way over as a United codeshare. By the warped logic this sort of thing goes by, that counts. On the way back, they routed her via Boston, a feat I was unable to duplicate. So she'll be on her own once we get to Frankfurt.
Though I had flown Lufthansa on intra-European flights before, I had never flow it across the pond. All in all, it was fairly nice. The check-in agent took our old seat assignments (in separate rows of the plane) and gave us some crew rest seats I guess they decided they didn't need. They were standard economy seats (i.e., not very comfortable), but they were window and aisle in a 2-4-2 combination. All in all, very survivable.
The Lufthansa "Senator's Club" in Frankfurt was a nice place to relax, although there was more smoking than you'd get in an American facility. They had a room with lounge chairs, which was a nice way of relaxing after the plane. Our flight to Zurich was fairly empty, and I slept through it.
