Flights home from Berlin booked, to the tune of 86,000 miles + $350 in fees and taxes (for biz class). I'm actually lucky to get a biz class miles redemption under 100k, even just one-way. Some of us used to call Delta miles "SkyPesos", but I think that's actually an insult to the peso now, so I'm going with "SkyRubles" going forward. 300,000+ miles for RT biz class to Europe from the East Coast? In March? Get dafuq outta here, DL. A round-trip booking would've made my itinerary a bit tougher anyway.
As for getting to Deutschland, I've poked around for a couple of months, but the best option I've found and keep coming back to is a so-called
"Fifth Freedom" flight on Singapore Air from JFK to Frankfurt at a range of prices depending on class. Currently debating whether a 6.5-7 hour flight is worth the ~$675 difference between premium econ and biz. Singapore A380 biz class is legendary, and I can swing the extra cost, but I'd be lucky to get 2-3 hours of sleep on that short of a flight, even in the lie-flat seat. Not to mention that $675 savings would just end up getting added to the food/transit/museum entries/cover charge budget. Either way, I am already setup to go from DTW to JFK for 'only' 13,500 SkyRubles and $6 in taxes and fees, so that is a plus.
This is the tentative itinerary I've laid out:
Day 0: Red eye flight to FRA, arriving around 10a CET on Day 1
Day 1: Train to Stuttgart, overnight there
Day 2: Morning in Stuttgart, afternoon train to Munich
Day 3: Munich
Day 4: Munich
Day 5: Morning in Munich, afternoon train to Bamberg
Day 6: Bamberg
Day 7: Train to Berlin
Day 6: Berlin
Day 7: Berlin
Day 8: Berlin
Day 9: Partial morning in Berlin, but must be at TXL by 10am for 11:55 flight to AMS and connection to DTW.
And yes, I'm going in March. The weather may or may not be a bit dicey, but that's a risk I'm willing to take. Honestly, I think I'm more worried about the departure and arrival weather in the US. It sounded like March is a reasonably dry month in Munich, and is among Berlin's 3-4 driest months. I certainly have no problem with temps in the 30-60 degree (F) range.
