If you really like it there, wait to see what happens. Mesaba seems like a good company to work for. If you find yourself out of a job, look for another job that doesn't require that youresign your seniority number and wait to see what happens. You can always take soime time off, rack up your credit card bills and go backpacking in Europe or wherever it is that you've always wantd to go. All this if you are young, single, and good looking. If you have a family to take care of, by all means start working on a plan B, but don't leave Mesaba unless they let you go.
Best of luck to you and to all the Mesaba brothers!
