Hi N830MH,
Can you demonstrate a need (specifically, miles 7 points discussion) for this new forum, to justify moving the airlines from their existing forum?

Without demonstrating a need, I cannot support a new forum.
Q. Are there so many threads created by these airlines that the existing forum is a problem?
A.

Some data points on threads for these airlines would be my first requirement to consider your proposal. Perhaps you can see how similar spin-out proposals were run: e.g.
- Airlines of India TB thread;
- Airlines of Greater China TB thread.

Cheers,
BB
