NEW YORK (NYTIMES) - Ms Maria Boyd-Scott turned 60 last month, and she and her partner, Ms Joey Boyd-Scott, 68, celebrated the milestone in style.

They flew business class to Amsterdam, stayed at a Hilton hotel for two nights and then headed to France for two nights at the Waldorf Astoria Versailles.

The damage to their wallets? Thanks to their part-time travel jobs, their flights cost US$462 (S$635) in total - they paid only the taxes. The Hilton in Amsterdam was US$55 a night and the five-star hotel in France was US$75 a night.

They are part of a growing class of auxiliary travel workers who are stepping in as airlines and hotels, already struggling with thinned ranks after mass layoffs in 2020, now contend with the great resignation of employees.

Many of these new workers are seasoned, silver-haired and shameless about the fact that they are in it for the perks.

Ms Maria Boyd-Scott says: "I have a lot of friends in the airline industry, and I watched them all fly and thought, 'Well, that would be fun.' So I applied when I was 58 years old and I got a call."

She took a job as a ramp agent for United Airlines in May 2021, loading and unloading baggage at Ontario International Airport in California's San Bernardino county.

Most weeks, she puts in 15 hours, the minimum to maintain access to the flight benefits afforded to all United employees, which include unlimited standby travel for herself and a loved one - free within the United States and deeply reduced internationally.

The travel industry is facing significant labour shortages. In June, domestic employment in the American leisure and hospitality sectors was down nearly 8 per cent since February 2020, according to the US Bureau of Labour Statistics, leaving hotels, airlines and other travel operators ill-equipped to contend with surging demand.

That crunch - playing out in widespread flight cancellations, terminal halls filled with lost suitcases and diminished room service and daily housekeeping - is prompting companies to recruit at job fairs and sweeten the benefits with bonuses and same-day pay.

It is also pushing them to consider senior citizens for positions that are far from senior.

"We're open to anything," said Mr Dan Bienstock, chief people officer for EOS Hospitality, a hotel management company. "We have more job openings across the company than ever before, and we're thinking outside the box on how to retain talent."

More than half of the 38 properties in EOS' portfoliorely heavily on seasonal guests - and seasonal hiring.

The company is not actively targeting older workers for summer jobs, says Mr Bienstock, but is focusing its recruiting efforts on hotels' local communities to supplement the summer workforce long filled by international workers on H-2B visas.

Mr Eric Rubino, chief development officer for Extreme Hospitality, an asset management company working with more than 300 hotels, says: "The labour pool for the hotel industry has been hit very hard and these entry-level jobs have become harder to fill since the pandemic.

"For senior citizens, who maybe don't mind working so hard, they can say, 'I don't need the money, but that travel benefit means a lot.'"

Even those who do not need the money might now see the appeal of a little extra cash. Inflation is hitting record highs, and it is a phenomenon that affects retirees and those on a fixed income the hardest.

Mr Rubino estimates that since the beginning of the pandemic, at least 65 per cent of new hires at the properties he works with are either post-retirement or older than 50. Representatives for several major airlines, including United and Delta, say they are either not tracking these demographics or have not noticed a shift.

But hotel hiring managers are. "I've seen an influx of older workers," says Ms Stephanie Guibert, head of human resources for the Palm Beach Marriott Singer Island Beach Resort & Spa in Florida.

While her property has seen the number of applicants rise overall, "the biggest struggle is getting people to show up for the interviews or for their first day".

Older workers and those nearing retirement age, she says, are showing significantly better follow-through and so are being hired more often.

With their new part-time jobs, some older workers have found a chance to break in a passport for the very first time.

Ms Renae Mattimoe, 49, worked for her father's trucking company in Montana for 20 years. When he sold the business in 2020, she felt unmoored. Married with seven children, her only international travel had been to Canada in the 1990s, when Americans could still enter with just a driver's licence or birth certificate.

"When you have seven kids, you can't afford to fly," she says.

Earlier this year, she took a part-time position with Envoy Air - a regional carrier for American Airlines - at the airport of Bozeman, Montana. She checks people in, takes baggage and occasionally works on the ramp.

She also can now fly for free - or just for taxes if the destination is international. In January, she and a co-worker went to Madrid on American Airlines for US$46 each. The trip marked the first use of her passport. A visit to London followed.

She makes only US$20 an hour and is quick to point out that she could never have taken advantage of the job, or its corresponding perks, if she was not already financially secure.

"You can't pay your mortgage with flight benefits. You have to be in a position to be able to afford this," she said. "But it's surreal. I never imagined this would be my life."
