I was able to call UA twice and each time I told them I wanted it booked on UA metal but with the LH # for it, and both times they did it for me no problem 85$ cheaper.

Sometimes it is best to book the codeshares, but if you plan on upgrading the UA segment booked as a LH it is day of, luckily mine were S so I didn't care.

I did just book a ticket from WAS-DEL UA wanted 984$ for an S class, 1184$ for W, just decided to buy the same flights through Swiss, so same UA equipment but Swiss booked it as an E class which UA said was upgradable day of the flight and it only cost $1024, so sometimes booking that way can be beneficial if you don't care about the chance upgrades won't clear.
