(1) What is your home airport?VIE
(2) What types of fares do you usually buy ? Economy, occasionally discounted premium economy or business (e.g. N fare for prem.eco)
(3) How many miles do you usually fly each year? 50k/yr
(4) Do you have any kind of status at present? What is it? TK M&S Elite (*G), LH M&M Frequent Traveler (*S)
(5) What is most important to you in a FFP? Now that I have lounge access with TK *G, I'm looking for good award redemption rates (and possible free upgrades?)
(6) Which routes do you fly most often. About 2 trips to the US / year (West coast VIE-FRA/MUC-SFO or East coast VIE-IAD), Up to 2 trips to (South)-East Asia, and a few (~5) intra-European trips
(7) Preferred Airlines Being based in VIE, OS and LH are the obvious choices but otherwise any *A carrier that would get me the most miles (UA to the U.S.? Asian carriers to Asia?)
(8) Do you travel for work or pleasure? Work. Typically buying "best deal" fares - i.e. lowest, or if premium economy (or rarely business) is available at a great discount

A year ago I was LH M&M Frequent Traveler and since I'm not able to make Senator (100k miles), I was looking for another FFP to get *G for lounge access. I managed that this year - earned 65k miles with TK M&S, giving me *G for 4 years - great!

So now I want to decide where to start crediting my flights in 2020 - with the focus on Award miles, instead of Status miles - most probably either LH M&M (where I'm a Frequent Traveler and have about 17k miles in my account) or UA M+ (where I'm only a member and have almost nothing).

Having done a little bit of research, I know LH has higher surcharges on award flights than UA but I'm still unsure which would make more sense for me between the two. I tried to do some calculations of expected earnings (e.g.in the Miles and More calculator in the app, and through WhereToCredit.com) but it's a bit difficult, especially as Award miles earnings in LH M&M would be revenue based (the fare x 6) vs. booking class & distance for UA M+.

Take my upcoming flight as an example:
VIE-MUC (LH, H class) + MUC-SFO (LH, H class) + SFO-FRA (UA, N class) + FRA-VIE (LH, Y class)

The confusing part for me here is the Premium Economy (N) operated by UA bought on a LH ticket - does this really only earn 25% (status miles) on M&M and 0% (status - and what about award?) on M+?

If that's the case (and my calculations are correct), then for this flight (ticket cost around 1000€):

on LH M&M: 6000 award miles, 12674 status miles (including the 25% FF bonus)
on UA M+: 6085 award miles (according to WhereToCredit), 6085 / 5 = 1217 PQP according to UA's new system from 2020

As I mentioned above, the status miles / PQP are lower priority as I have TK *G and I won't make Senator (but could at least extend my FF status), but I *might* be able to make Premier Gold (if I'm "lucky" to fly enough on the right fares, and make sure to have 4 UA segments) - but I'm not sure if it's worth chasing?

And for the award/redeemable miles - suppose I can earn between 40-65k per year in either program, which one would be better?

Another consideration would be more long term - I guess the new UA M+ rules make attaining status more difficult for me (than it was with the old rules - but Premier Gold is still more attainable than Senator), not sure about the new LH M&M announced for 2021 - perhaps Senator would be more within reach, if I fly more / premium cabins in the future? And while I can switch and credit to various FFPs, I guess sticking with one of them for the long run is preferable - i.e. for example, it's probably better to have 90k miles in one program, rather then 50k and 50k in two, right?

Thanks!!
