No NSL will ever work

Base it on expirience or flight time

250 hours min for commerical license

$25,000 is min pay to fly for airline
Pick your pennies per hour

250-2500 hours you get paid 3.5 cents per hour of expirence or 25K which ever is more
So at 2500 x .035 x 70hrs/month x 12months= $73,500 per year

2501-5000 3 cents per hour or $73,500 which ever is more
5000 x .03 x 70 x 12 = $126,000 per year

5001 - 7500 2.5 cents or $126,000

7500 hrs x .025 x 70 x 12 = $157,500

10000 hrs x .0225 x 70 x 12 = $189,000

Some theoretical max pay. Captains get a 30% boost in pay. You can not be a captain unless you have 2500 hours.

In order to fly certain aircraft you need certain time.
This will keep high time pilots in the cockpit. Example
737 FO you need 2000 hours
777 Captain 12000 hours ETC....

All airlines would be required to pay the same rate. So they would all have a level playing field. They could not blame the company failures on the pilot group because all would be payed the same. Unions could focus on work rules rather than pay.

Just a thought
