Well, let me put it this way: The pay situation will undoubtedly change at some point in the future. How long in the future is anyone's guess. That said, I'd still recommend Omni to someone looking at moving out of RJs into bigger equipment. You'll log heavy jet, international (I've been to 4 countries in the past 4 days, not including the US), oceanic, ETOPS, glass/FMS experience. Should you decide to move on to a major airline in the future, your resume will most certainly stand out among those with thousands of hours of domestic RJ experience.
YMMV of course, but this flying is excellent experience.
