I don't know the history of what other airlines have achieved in retro.

All I know is that last time we got a "ratification incentive" instead of "retro"

It was a chunk of money given to ALPA by the company and divided amongst us based on ALPAs plan. It was not based on credit hours flown since the contract became amendable. It was equally distributed by seat and longevity.

Another point worth mentioning about it; it was a good chunk of money ($75 Million I think) but it was needed to satisfy issues from the previous contract and bankruptcy. The company and union had a LOA dating back to bankruptcy that said the company would negotiate pay raises if/when Frontier returned to profitability. Of course they never did that (shocking) and therefore had to sweeten the pot to get us to sign the new contract. I hope that makes sense.

Anyhow, for me, the ratification incentive maybe amounted to 1/3rd of what full retro would have been.
