My wife is an aviation legal professional, and though she's not a lawyer (paralegal) she is a licensed commercial pilot with turbine experience and that has helped her immensely in getting hired by law firms and companies that specialize within aviation.

Aviation law is a very narrow niche in the legal field; there are only a handful of firms that actively practice such law and they're pretty much in major metros. The other option are companies and pilot unions.

I seem to recall hearing ALPA was paying some or all the cost for a Mesa FO to attend law school...don't know if that was urban legend or what but it may be something for someone to look into.

The early years of being a lawyer are often worse than the early years of being a pilot; you may make more coin but the hours and workload are FAR worse.
