Do you have the competitive times already?

I worked as a full-time sim IP at Simuflite after I got furloughed at AA and it was not a problem getting on with FedEx. I had not seen an actual jet for about 2 years but I was (according to every piece of paper the FAA had) current and qualified in the left seat of a multi-engine jet. I explained everything to the ACP my sponsor was working with and it was no problem - in fact we had one other former AA guy get hired at FedEx, and another got hired at UPS - both from sim jobs.

Bottom line - neither company will count sim time toward your total, but the "time off" probably won't count against you. If you are competitive going into the sim job it probably won't hurt you. If you don't have the times to be competitive then you'll just be treading water.

Good luck!
