While its unlikely the 747-8I will be selling as much as the 777-300ER, there are still several potental airlines that could order the place, such as Cathay Pacific, Turkish Airlines, Emirates and Air China* for example...
Its only been operating for 1-2 years and airlines like to wait after its launch in service before seeing if its worth ordering...
*Maybe British Airways (might) be included and Lufthansa might want to order more...
We can judge if it been sucessful in the mid-2020s...
