"Emirates airline" (sic) is the correct name. The lower case "a" is intentional (why, I don't know) but is used in all public materials related to the airline.

It should also be noted that Skywards is not directly affiliated with Emirates airline, but rather is a separate operating division within the Emirates Group (http://www.emirates.com/gh/English/about/emirates.aspx).

Therefore, IMHO, the forum name should be "Emirates airline (Skywards)".
