Hello all. I've been trying to figure out if this is a valid bookable routing. Essentially I want to go to Europe next year over the summer for a few weeks and business class awards are obviously hard to come by. However, TK has excellent Businessn class availability all summer/year so I want to fly into Istanbul on or around 7/2/2014 and move around Europe for a couple weeks on a stop over and then fly from CDG to BKK on or about 7/17/2014 on TG or LX with BKK being my destination (both show a ton of options in Business, with TG having open availability in First). Finally I want to go from SIN to LAX on BR or NH Business or Economy (all options are open). My primary concern is if this route is even possible to book on one ticket and if so, is it something I need to call for because I can't seem to get more then one section of the ticket to price on United's site even though all legs are available.
