Airlines operate in a market that's dictated by supply and demand: If more people want to fly a specific route than there are available seats, then tickets on those flights cost more.

That makes scheduling and predicting demand a huge part of maximizing revenue for airlines. There are, however, numerous factors that go into how airlines decide which flights to put on the schedule.

Every airport has only a certain number of gates, flight slots and runway capacity, limiting carriers' flexibility. That's why during times of high demand — like flights to Las Vegas during Super Bowl week — do not usually translate to airlines sending more planes to and from that destination.

Airlines generally do try to add capacity every year. That's become challenging as Boeing has struggled to keep up with demand for new airplanes. If you can't add airplanes, you can't grow your business. That's caused problems for the entire industry. 

Every airline retires planes each year. In general, those get replaced by newer, better models that offer more efficiency and, in most cases, better passenger amenities. 

If an airline can't get the planes it had hoped to add to its fleet in a given year, it can face capacity problems. And it's a problem that both Southwest Airlines (LUV) and United Airlines have addressed in a way that's inevitable but bad for passengers. 

Southwest slows down its pilot hiring

In 2023, Southwest made a huge push to hire pilots. The airline lost thousands of pilots to retirement during the covid pandemic and it needed to replace them in order to build back to its 2019 capacity.

The airline successfully did that but will not continue that trend in 2024.

"Southwest plans to hire approximately 350 pilots this year, and no new-hire classes are scheduled after this month," Travel Weekly reported. "Last year, Southwest hired 1,916 pilots, according to pilot recruitment advisory firm Future & Active Pilot Advisors. The airline hired 1,140 pilots in 2022." 

The slowdown in hiring directly relates to the airline expecting to grow capacity only in the low-single-digits percent in 2024.

"Moving into 2024, there is continued uncertainty around the timing of expected Boeing deliveries and the certification of the Max 7 aircraft. Our fleet plans remain nimble and currently differs from our contractual order book with Boeing," Southwest Airlines Chief Financial Officer Tammy Romo said during the airline's fourth-quarter-earnings call. 

"We are planning for 79 aircraft deliveries this year and expect to retire roughly 45 700 and 4 800, resulting in a net expected increase of 30 aircraft this year."

That's very modest growth, which should not be enough of an increase in capacity to lower prices in any significant way.

United Airlines pauses pilot hiring

Boeing's  (BA)  struggles have had wide impact across the industry. United Airlines has also said it was going to pause hiring new pilots through the end of May.

United  (UAL)  Fight Operations Vice President Marc Champion explained the situation in a memo to the airline's staff.

"As you know, United has hundreds of new planes on order, and while we remain on path to be the fastest-growing airline in the industry, we just won't grow as fast as we thought we would in 2024 due to continued delays at Boeing," he said.

"For example, we had contractual deliveries for 80 Max 10s this year alone, but those aircraft aren't even certified yet, and it's impossible to know when they will arrive." 

That's another blow to consumers hoping that multiple major carriers would grow capacity, putting pressure on fares. Until Boeing can get back on track, it's unlikely that competition between the large airlines will lead to lower fares.  

In fact, it's possible that consumer demand will grow more than airline capacity which could push prices higher.

Isolated. Abused. Overworked.

These are the themes that emerged when I invited nine Black women to chronicle their professional experiences and relationships with colleagues as they earned their Ph.D.s at a public university in the Midwest. I featured their writings in the dissertation I wrote to get my Ph.D. in curriculum and instruction.

The women spoke of being silenced.

“It’s not just the beating me down that is hard,” one participant told me about constantly having her intelligence questioned. “It is the fact that it feels like I’m villainized and made out to be the problem for trying to advocate for myself.”

The women told me they did not feel like they belonged. They spoke of routinely being isolated by peers and potential mentors.

One participant told me she felt that peer community, faculty mentorship and cultural affinity spaces were lacking.

Because of the isolation, participants often felt that they were missing out on various opportunities, such as funding and opportunities to get their work published.

Participants also discussed the ways they felt they were duped into taking on more than their fair share of work.

“I realized I had been tricked into handling a two- to four-person job entirely by myself,” one participant said of her paid graduate position. “This happened just about a month before the pandemic occurred so it very quickly got swept under the rug.”

Why it matters

The hostility that Black women face in higher education can be hazardous to their health. The women in my study told me they were struggling with depression, had thought about suicide and felt physically ill when they had to go to campus.

Other studies have found similar outcomes. For instance, a 2020 study of 220 U.S. Black college women ages 18-48 found that even though being seen as a strong Black woman came with its benefits – such as being thought of as resilient, hardworking, independent and nurturing – it also came at a cost to their mental and physical health.

These kinds of experiences can take a toll on women’s bodies and can result in poor maternal health, cancer, shorter life expectancy and other symptoms that impair their ability to be well.

I believe my research takes on greater urgency in light of the recent death of Antoinette “Bonnie” Candia-Bailey, who was vice president of student affairs at Lincoln University. Before she died by suicide, she reportedly wrote that she felt she was suffering abuse and that the university wasn’t taking her mental health concerns seriously.

What other research is being done

Several anthologies examine the negative experiences that Black women experience in academia. They include education scholars Venus Evans-Winters and Bettina Love’s edited volume, “Black Feminism in Education,” which examines how Black women navigate what it means to be a scholar in a “white supremacist patriarchal society.” Gender and sexuality studies scholar Stephanie Evans analyzes the barriers that Black women faced in accessing higher education from 1850 to 1954. In “Black Women, Ivory Tower,” African American studies professor Jasmine Harris recounts her own traumatic experiences in the world of higher education.

What’s next

In addition to publishing the findings of my research study, I plan to continue exploring the depths of Black women’s experiences in academia, expanding my research to include undergraduate students, as well as faculty and staff.

I believe this research will strengthen this field of study and enable people who work in higher education to develop and implement more comprehensive solutions.

The Research Brief is a short take on interesting academic work.
