*A Carriers into BLR
 

Its been a few years since I had occasion to go to BLR. Looking at SFO-BLR, the Star Alliance carriers flying into BLR seem unchanged:
FRA-BLR on LH
BKK-BLR on TG
SIN-BLR on SQ

Did I miss any new ones? Flightstats by Route doesn't show anything new.

I see these:
BRU-BLR (9W, but ending soon).
LHR-BLR (9W, BA but that doesn't offer earning into UA MP).
CDG-BLR (Air France, not a Star Alliance or earning into UA MP).
HKG-BLR (CX?, not a star alliance or earning into UA MP).

Given these, looks like the choices remain unchanged:
SFO-FRA-BLR (UA or LH and then LH).
SFO-BKK via NRT on UA or on TG and then TG to BLR.
SFO-SIN via NRT on UA or on SQ via HKG/ICN and then SQ to BLR.

Am I missing anything?

That's it for Star.

Emirates is not technically *A, but has a partnership with UA, so you could go SFO-DXB-BLR on Emirates or UA/Emirates and collect UA miles (although not EQMs to my knowledge)
