All new hires will be given EWR as a starting base for the next year.
737 you will be able to bid out of EWR in a year
320 you will be able to bid out to IAH pretty quick but will be in IAH or EWR for at least a year.
76T you will be in EWR for 5+ years.
Just basing this off what I have seen on the last bids. New hires have not been awarded anything but 76T and 737 in EWR since SLI.
