Hi - I'm kind of new to this so can use some expert advice. I want to purchase a RT ticket from LAS to VIE (including LX TATL) via ORD/ZRH, which I can find and price easily on the LX website. The segments between LAS/ORD and return are on a UA codeshare. However, when I go to the UA website to duplicate, I cannot get it to appear. I narrow the departure times to match the offering on the LX website, make sure to uncheck "United Airlines Flights Only" and increase "Number of Flights to Display" to 50. No joy. Some LH flights show up, but no LX. Again, this is to purchase, not award travel. Assume I should just buy from LX? Thanks.
