More than 7,000 Delta Air Lines employees in Michigan will feel the love on Valentine's Day with one amazing bonus.

They'll receive a bonus check that adds up to roughly two months of pay. Yes, amazingly, one bonus check could cover the amount of income that jewelers suggest you spend on an engagement ring — two months worth of income.

Maybe it's time to commit and shop for that diamond ring after all.

And the bonus cash doesn't stop at Delta.

Autoworkers in Michigan and elsewhere are likely to hear about the size of their annual profit sharing checks in February, too.

Ford Motor Co. is expected to make its profit sharing news on Feb. 4 when it releases 2019 fourth quarter and full year financial results at 4:05 p.m. after the stock market closes.

On Feb. 5, General Motors will announce the amount that UAW-represented hourly employees will receive for profit sharing checks. The GM negotiated formula with the UAW is $1,000 per every $1 billion in North America earnings before interest and taxes for represented employees.

Fiat Chrysler Automobiles is likely to announce details of its profit sharing checks for UAW-represented workers on Feb. 6 when FCA's fourth quarter and year-end earnings are released.

The UAW bonuses have meant a sizable infusion of cash for metro Detroit workers in recent years.

Last year, for example, UAW-represented workers at General Motors received profit sharing checks of $10,750 before taxes.

At Ford, the profit sharing checks amounted to $7,600 on average for a majority of the company's 56,000 hourly UAW workers in 2019.

At FCA, union workers received an average of about $6,000 in profit sharing checks, again before taxes, in 2019.

How big will the bonus cash be in 2020?

It's hard to say exactly but Ford and FCA's payouts could be close to last year's amounts and GM could be down slightly, experts say.

"Despite the gloom and doom by some, the auto industry had a very good year supported by a robust economy, low unemployment, and low interest rates," said David Kudla, CEO of Mainstay Capital Management.

"And, consumers are buying up profitable SUVs, trucks, and crossovers, upping the average transaction price to record levels."

All those factors help profits and would point to larger bonus checks. But other issues will come into play.

"There were certainly stumbles by the Big Three," Kudla said. "The strike hurt General Motors squarely in the pocketbook. And Ford lost a lot of traction with missteps on their truck launch in the latter part of the year. Fiat Chrysler greatly increased its incentives to move vehicles off the lot."

"All in all, and not knowing what may come out in the upcoming earnings reports, we do not see a dramatic change on average when it comes to the bonus payouts for last year’s performance for Ford and Fiat Chrysler," he said.

But Kudla cautioned that the impact of the 40-day UAW strike at General Motors will be reflected in lighter profit sharing checks for 2020.

Delta will pay out $1.6 billion in profit sharing to its 90,000 employees throughout the airline, translating to a 16.6% payout for eligible employees. That percentage equals about two months of pay, according to the airline.

Delta has a hub at Detroit Metro Airport.

The $1.6 billion in bonus cash is the largest profit sharing pool in Delta's history. It's the sixth year in a row that the Atlanta-based Delta will pay out more than $1 billion in profit sharing.

What to do with your windfall

Some tried-and-true tips apply if you're getting one of those bonuses:

Look at your big outstanding bills — say credit card debt or student loan debt — and use a once-in-a-lifetime windfall to save money in the long run and stop that interest from building.

Put a little extra in any emergency fund.

Don't take any bonus for granted by simply letting that money flow easily into your checking account where it can be quickly spent.

Think about bigger goals — retirement, saving a down payment for a new home, sending your children to college, and yes, popping the question and getting married. Time to share the love.
