flyman : Yes. Even 16 years ago, my employing airline allowed 2 OML's to fly together but NOT if they had the same restricting condition. The whole thing gave Rostering a big headach. However, there was no question that at initial hiring, a full, unrestricted, Class one was required.
I know of no major airlines that will accept an OML on initial hiring. Just search through any hiring website. Of course, some employment possibilities might exist but before embarking on very heavy financial outlay for "mights, maybes, not unheard of", type prospects shows an attitude to risk that is not impressive.
