Only regional pilots are underpaid, and then only as low senority FOs. Also, regional airlines don't sell tickets, they sell flying services to larger arlines, the cost of which is largely determined by the price of that regional's labor. I don't think a ticket tax would be the best solution. Maybe reduced pay for higher senority pilots with a raise at the bottom? I'd actually like to see a flatter pay structure. For example: FOs earn $45k, captains $75k, with opportunities to make more, such as overtime, holiday pay, longevity bonus, etc.
