I only waited 3 days for IOE when I was on the Bro and 5 weeks for IOE on the jet. During that 5 weeks I called 4 times a week until I got my answer, our IOE coordinator told me that all MKE pilots had priority and it will remain so through the end of the year. Mainly because we're short in MKE and every month we gain flying (in MKE) so it's a struggle to train pilots fast enough to keep out with the line demands. If you get any other domicile you'll sit for 4+ weeks until they can squeeze you in. Bid MKE if you want to complete IOE ASAP otherwise enjoy your 4 weeks off with full reserve pay and use your pilot privileges to travel (go see friends, family, abroad, etc.).
