I recently took a 737 FO on our JS from IAH to CVG.
After the exchange of pleasantries- the pilot said he was going on 17 days of night flying and had to JS back into CVG for more fun. No catering, no gateway, no hotels, no nothing.
I would say the 737 for southern has to be the worst flying job in aviation.
If a job is what you need. Go to eagle, or PSA get a flow through, and hey- you may even find the occasional FA to keep you warm.
