I am thinking about upgrading one of these flights to 1st class using Miles & More miles. There are two of us, so the upgrade would cost 2x45k on the UA flight and 2x65k on the LH flight.

The question is, which one should I upgrade? I am very familiar with the LH long-haul C and F experience, and also quite familiar with UA's long-haul C and short-haul F, but haven't flown UA in first on an intercontinental flight.

I would lean towards upgrading the very very long UA flight, but if their long-haul F product is anything like their intra-USA F then it's simply not worth it.

A big benefit of upgrading the LH flight would be the use of the F terminal upon arrival in FRA. (We have a 3-hour layover in FRA so we could make good use of the time, especially after an 11-hour fight.)

Any advice?

TIA
