I need help! I need someone who can help me figure out a very special trip for my husband and me (his first trip to Europe) while using FF miles AND while going during a set time period.

Our FF account info:
Delta SkyMiles account: 155,599 miles
My NW account: a little over 27,000 miles
His NW account: a little over 24,000 miles
His US Airways account: a little over 45,000 miles

Our IDEAL goals:
Dates: 8/27-9/4
Direct RT flights from MSP to LGW
First class

Our ACCEPTABLE goals:
Dates: Roughly 7-8 days anytime between 8/26 and 9/5
Direct RT flights anywhere close by in Europe (Amsterdam, Paris, etc.) then we can figure out how to get to or from London once there.
Coach, as long as we're at a window

My husband is convinced this is simply not possible. I spent about an hour and a half with two different Delta agents (since that's where the bulk of my miles are) and came away very discouraged. Will I get a different result if I approach the trip through NW? They are the ones, after all, that have direct flights between MSP and those cities I named above. Delta swore to me that since they're partners with NW that they had all the flight info right there.

The FIRST Delta agent told me she had a direct outbound (flight 44) on 8/27 (perfect!) and a Continental connecting inbound through Houston on 9/5 (not ideal, so I said I'd call hubby).

The SECOND Delta agent told me no, that there was NOTHING available the ENTIRE acceptable time I'd given her, unless I want to use SkyChoice (aka SkyScam) and use double the FF points to get any available coach seat on the plane. Doesn't sound like a good deal to me.

So where do I go from here? Just for fun I'm going to call NW and find out what I can do from their end. But are there avenues I haven't thought of? Specific agents I should be talking to? Since this is the first international trip I've coordinated, I'm feeling a little overwhelmed by the possibilities.

Can you help? WWFTD? (What Would FlyerTalk Do?)
