Why it's awesome: Thai Airways has long been an industry leader for quality service, so it's no surprise to find the Thai national carrier high up on the list. Though its most heralded products are its business and first-class services, fliers found its economy seats to be of high quality as well.

Economy fliers on Skytrax also noted the crew's friendly demeanor and delectable dining options.

Moving up six spots to number 13, Thai Airways took home the award for World's Most Improved Airline as well as the title for World's Best Airline Spa Facilities.
