Yes, good time spend down your frequent flyer mile balance (I talked with a guy in Sydney last week who lost like 300K miles when Ansett went TU...)

Flew Lufthansa biz years ago and service/food were both good. Last year I scoped out an LH flight from Vancouver to Frankfurt, but wound up going another way. LH has seat maps on their web site. They have their own version of the flat first-class seat/bed that looked decent. IIRC, first class on their 747 is on the upper deck. Not as good IMO as in the nose as it is harder to get a seat away from traffic/galleys/toilets.

Lots of carriers are downsizing equipment on routes due to pitiful load factors. Friends just got back from London and BA was using a 767-ER they said in place of the 747 previously used on that route. I'd just keep that in mind, but there's first class on LH A340s, too, I think.

It is getting harder and harder to book award travel, so I would do it as soon as you can. Good luck getting a seat on any weekends, better luck on mid-week seats.

With your excursion desires, I'd try for an open-jaws booking, fly into Frankfurt, say then return from Amsterdam or Paris or London, depending on what you can get, seat-wise. Those first-class beds are awesome on the Atlantic eastbound as far as getting some real sleep goes, but I don't usually sleep on the westbound, so care less about it then. If you are in Amersfoort, you'll just be a skip from Amsterdam, so how could you miss that? If you are determined to rock climb, I think most of that is far away from Amsterdam. Since I think everybody should visit Paris (for good or ill!), here's what I'd do:

- take Thalys from Amsterdam to Paris
- see Paris for a few days
- take train/TGV to Valence and pick up rental car
- drive up Les Grand Goulets and over the Vercors
- rock climb (I met lots of Brits rock climbing around Die)
- return car at Nice Airport
- take LH connector flight to FRA and back home

And, "Real Soon Now" is right. And keep checking. You can maybe book a provisional reservation and then improve the itinerary before being forced to issue the ticket. Lots of folks cancelling, unfortunately, so you may find better routes/seats open up as you check back.

Hell, if I am unemployed in July, I just might have to extend my trip to that wedding!
