Looking for a flight from Chicago Or Minneapolis to KTM. Anyone knows which airlines,
I been looking through Priceline but didn't find anything cheap so far.

Turkish airline may be cheaper but not suggested by travelers.

avoid turkish airlines at all cost. you are better off with anything other than tk, personla experience.

Good luck finding cheaper during December and January. I have been looking from last week and everything is $ 2000.00, including Turkish. Flying from DFW, Dallas TX. I had a Reservation in China Southern Airlines flying Dec 14 and coming back Jan 14 for almost $ 1800. Now same ticket is extra $ 400. Travel agent told he that airlines cancel the reservation and it was less than 24 hrs. They might have made a mistake.

Try google\flights. I am looking one for $ 2000.00 via AA, and Qatar (london\doha) and coming back with Etihad and AA (Abu Dabi\London or Paris\Frankfurt).
I am planning to wait till tomorrow and get it. I hate AA (bad experience), other than that its a 30 hrs flight both ways. Off course lots of money.

Well try finding flight by China Southern (They might not have direct flight from MSP or Chicago O hare) but you might get a ticket from new york where they fly directly to gonzau China and I heard that its fare is preety affordable and cheap and service kinda good too.

Have you tried to call the contacts on the front page of sajha? They have pretty reasonable price. I try cheapoair.com at first and then bargain the fare with the companies listed on the homepage. **try google flights as well***https://www.google.com/flights/?f=0 
Ive heard Turkish airlines has improved its service. My in-laws came to US via Turkish Airlines. I like their flight schedule.
