UA/LH codeshare questions
 

My apologies as these are probably answered in other threads, but searches aren't getting me to answers very efficiently tonight.

If I book an LH flight in C as a UA codeshare SFO/FRA:

1. Do I receive flight miles AND 1P credit AND purchased business class bonus?
2. Do I check in at United or at LH?
3. Do I have access to RCC's or LH lounges or both?
4. Is there any benefit to booking the LH flight as the actual LH flight rather than the UA codeshare?

Sorry about this again, just can't seem to find all the detail in one place.

Thanks!

1. Do I receive flight miles AND 1P credit AND purchased business class bonus?
yes - but the miles will not count toward 1 Million Miles.

[i]2. Do I check in at United or at LH?
LH

[i]3. Do I have access to RCC's or LH lounges or both?
both

[i]4. Is there any benefit to booking the LH flight as the actual LH flight rather than the UA codeshare?
UA/LH: you can't upgrade such a code-share (not with miles nor with vouchers) - you could upgrade a LH/LH with UA miles (you need to ask UA for a paper voucher to do so) or a UA SWU (on standby basis only at check-in or the gate).
