As SAS' departure from *A is now looking imminent, and I'm still expecting a significant share of my travel to be on *A carriers, I need at new *A FF scheme to credit my flights to.

The obvious choice would be LH, but I'm not a big fan of the new changes where you only earn status miles on Lufthansa Group airlines as I'm expecting a significant share of my travel (especially in C) to be on other airlines. TK could be an option, but I'm also worried about the changes, where each leg of an award trip is charged separately - as I would practically always need at least one layover in Europe for any longer trip, I believe this would significantly dilute the value.

(1) What is your home airport?
Copenhagen, CPH

(2) What types of fares do you usually buy ?
Intra-Europe Y and inter-contintental (Africa & Asia) C. About an even split.

(3) How many miles do you usually fly each year?
At least 25k-50k

(4) Do you have any kind of status at present? What is it?
SAS Eurobonus Gold

(5) What is most important to you in a FFP? (Frequent upgrades on travel, priority services when flying the airline, good award redemption rates, free lounge access, etc.)
#1 priority is ability and ease to retain Star Gold (for fast-track security & lounge access).
Ideally I want a scheme where I can earn status no matter which *A airline I'm flying on (including no requirement that X number of flights per year is on a specific carrier).

(6) Which routes do you fly most often? (US Domestic, Transpacific etc)
Intra-Europe (primarily London, Amsterdam, Brussels)
Inter-continental (primarily East Africa and India)

(7) Preferred Airlines
Fairly agnostic. Historically a significant share has been LH, LX, TK and ET (in addition to SK). As AI has now started a direct flight CPH-DEL, I could see myself flying more with them also going forward.

(8) Do you travel for work or pleasure? (Can you chooose your airlines, class of service?)
Fairly extensively for work. I can choose airlines, subject to there not being a significant price differential. Inter-continental flights are C, intra-Europe is Y.
