• It's a bad day to try to take a flight to or from Germany.
• A mass strike has caused huge disruption at the country's airports on Monday.
• 94% of flights were canceled at Frankfurt Airport, the country's busiest, a German news agency said.

Hundreds of thousands of passengers are facing disruption due to a strike in Germany, which has led to almost all flights at the country's busiest airports being canceled Monday.

The 24-hour walkout began at midnight on Monday and immediately caused mass disruption.

At Frankfurt Airport, the country's busiest, 94% of the day's 1,116 scheduled takeoffs and landings have been canceled, the German news agency dpa reported.

"There will be massive disruptions at Frankfurt Airport all day today," its website says, adding that passengers should not travel to the airport.

Munich Airport expected operations to be "severely disrupted," while Berlin Brandenburg Airport said it will have no regular flights.

According to data from Cirium, 108 flights are scheduled between Germany and the US on Monday, accounting for over 31,000 seats.

On Friday, the service workers union ver.di called on public-sector employees and ground and security staff to go on strike.

It also targeted airports in Hamburg, Bremen, Hanover, Düsseldorf, Weeze, Dortmund, Cologne/Bonn, Leipzig/Halle, Stuttgart, and Karlsruhe/Baden-Baden.

Jens Ritter, the CEO of flag carrier Lufthansa, said in a Sunday LinkedIn post that he was "stunned and really worried."

"What Verdi calls a 'warning' strike is again bringing air traffic to a halt," he added, and called for "cooperation instead of confrontation."

A warning strike is a common tactic in German labor negotiations. Monday's action relates to two separate disputes — one for airport security workers and a wider one for public-sector employees.

Ver.di said negotiations for the more than 2.5 million federal and local government employees across Germany will continue on Friday.

It is calling for an 8% pay increase with a minimum increase of 350 euros ($380) a month, plus higher bonuses for stressful shift work and three more days off.

For aviation security workers, the union wants better occupational health and safety, 30 days of holiday, an annual bonus increase, and other bonuses.

Ver.di also wants restrictions on fixed-term contracts, saying that most aviation security specialists are hired on 24-month contracts, many of whom are then replaced by newly trained employees.

"Public employers should know that we are assertive. This will be made clear again in the coming days," said ver.di chairman Frank Werneke on Monday.

• Trump's latest Ukraine moves put the future of F-16 fighter jets in Ukraine at risk.
• Europe has some jets that would suit Ukraine just as well, or even better.
• But there are far fewer of those planes and changing jet type now for Ukraine would be hard.

US-made F-16s were the first Western fighter jets to arrive in Ukraine, and since then they've helped to defend the country against Russian air strikes.

But President Donald Trump ordered a pause in US military aid to Ukraine last week, meaning Europe may need to find ways to fill the gaps, including in the air.

Europe, home to Ukraine's staunchest allies, has fighter jets that are similarly suited to Ukraine, but there are far fewer of them, and switching to those jets would cause a host of problems that Ukraine can little afford.

Celebrated in Ukraine

Ukraine began asking for F-16s almost immediately after Russia's full-scale invasion in February 2022, and celebrated their first arrival in August 2024.

The jets, built by Lockheed Martin but supplied to Ukraine by the country's European allies, have had some notable successes in Ukraine.

Peter Layton, a fellow at the Griffith Asia Institute and a former Royal Australian Air Force officer, said Ukraine's F-16s have shot down "numerous drones and cruise missiles," as well as hitting ground targets near the battlefield.

And while air warfare experts say Ukraine has not been given enough of them to take on Russia near the front lines — or to change the wider direction of the war — they've been effective air defenses.

Many of Ukraine's allies have more F-16s they could give, and Trump's actions could motivate them to send more. But because F-16s are American-made, Trump could block them from being sent to Ukraine.

European countries had to wait a long time for US approval to send their F-16s in the first place.

Layton said the US could also stop supplying spare parts, so that Ukraine's F-16 fleet "gradually goes unserviceable."

And while European countries have plenty of spare parts, if the US withholds approval to transfer those, European nations "will not be able to supply Ukraine," he added.

Europe's alternatives

Ukraine already has some European jets: Mirage 2000s. But only a total of six have reportedly been committed so far.

Those jets are seen as helpful for Ukraine, but not necessarily the best fit for the type of fight there.

Sweden's Gripen aircraft, made by Saab, is widely seen as the best fit, even better than the F-16. It was designed with a fight against Russia in mind. As a result, it can take off from civilian roads and is easier to maintain.

Justin Bronk, a leading airpower expert at RUSI, said that "on a platform level, the Swedish Griffin would be a better fit for Ukraine's requirements on almost every level, just platform to platform."

But none of those jets have so far been committed to Ukraine.

Europe also has other jets, like the Eurofighter Typhoon, but those haven't been committed either.

Set up for F-16s

A major problem facing Ukraine is that its program is heavily geared toward F-16s, and switching to another jet type would cause plenty of issues.

When asked last month if Sweden was considering giving it Gripens, Pål Jonson, Sweden's defense minister, told Business Insider he was "having a dialogue" with Ukraine and other countries in the Air Force Coalition, a group of allies committed to helping Ukraine.

But he said it's "more challenging for the Ukrainians to absorb another fighter," so Sweden was being advised to focus on sending airborne sensors that can provide command and control for the F-16s.

Bronk said the Gripen could serve Ukraine just as well, or better, but "there's so much that goes and has gone into so far getting the F-16s up and running in terms of training — not just pilots, but maintainers — and getting all the logistics set up."

He added that "you couldn't just swap them out quickly."

Issues with training have created a bottleneck in getting the jets into the air over Ukraine and changing to a new type would create a whole new host of requirements.

Mark Cancian, a defense expert at the Center for Strategic and International Studies, said that with new jets, "the major constraint is pilots, and you can't just rustle those up in a couple of weeks."

He added that the important thing isn't so much the differences between F-16s and European jets, but the "timeline and numbers and costs."

There's also another problem related to European aircraft: there are far fewer of each compared to the F-16.

That's one of the main reasons the F-16 was seen as the best fit for Ukraine: there are lots of them, as well as plenty of spare parts and people qualified to work on them.

George Barros, a Russia expert at the Institute for the Study of War, called the F-16 "sort of the ideal model because of how versatile and universal the system is."

He also said that Europe could not train as many pilots on aircraft like the Gripen because "relatively fewer countries" operate them.

Europe has vowed to keep supporting Ukraine, but losing US help requires a big increase in spending, and some weapons will be much harder to replace.

Another jet type may be an option for Ukraine, if the F-16 is no longer available, but it's an option that comes with problems Ukraine can ill afford.

• Joe DePasquale sells sports cards online under the brand "Joe Hollywood."
• Last year, his company made more than $5 million in sales.
• He wants to use his wealth to give his kids the resources they need to succeed.

This as-told-to essay is based on a conversation with Joe DePasquale, founder of the Joe Hollywood brand. It has been edited for length and clarity.

Growing up, I didn't have much. My dad was involved in drugs, and my mom struggled with a mental illness that sometimes made it difficult for her to even go outside. It was a really difficult atmosphere. I remember coming home one day to strangers at our house; it was the local church dropping off donations for us.

My prized possessions were my sports cards. My grandfather bought me my first pack when I was 8, and I absolutely treasured the cards even as I got older. I went to college in Manhattan and missed many classes because I was buying cards for 5 or 10 cents on the street corner.

Eventually, I dropped out of college to take a job in finance, making $200 a week. That job felt like a bridge between where I was and where I could be. I moved up the corporate ladder, eventually reaching leadership in my finance company. But I never felt fully financially secure, especially seeing firsthand how tumultuous the market can be.

I started selling millions worth of sports cards

All the while, I was still buying trading cards until I had more than half a million of them. I rented a storage unit to keep them all. In 2022, I relocated from New York City to Atlanta for my finance job. I had my dream house and decided to bring my cards home. They filled almost my basement, so my wife, Dori, suggested it was time to sell some.

My oldest son, Joe Jr., was 10 at the time. He was excited by the idea, so we started selling cards online and eventually on WhatNot, a livestreaming marketplace. At first, we were filming in the basement boiler room; the show would end when my phone battery died. As we sold more, we moved to my younger son's train table and eventually to the Ping-Pong table.

Soon, we outgrew that, and I could justify converting a bedroom into a home office for selling cards. Last year, my company did more than $5 million in sales on WhatNot.

I take each of my kids on individual trips

I don't like to talk about my personal wealth or net worth. But it's clear my three children, who are now 13, 10, and 6, are growing up very differently than I did.

We like to travel as a family, including a recent Thanksgiving trip to the Bahamas. Dori and I also do smaller trips with just one of our children at a time. We're preparing to take Joe Jr. to Disney — he's never been, and neither have I. This past fall, we took our daughter to New York City and did everything she wanted, including seeing the Rockettes. Our youngest wanted to eat grilled cheese on the beach, so we took him to Turks and Caicos.

Because of my success, I can spend quality time with each of my kids. That makes up for the fact that my quantity of time is sometimes limited since I stream for 24 hours each Friday through Saturday. I still reserve Sundays for faith and family, though.

I want my kids to have resources

I want my children to have access to every resource they need to succeed. Joe Jr. loves basketball, so I pay for every basketball team or clinic he asks for. Whether it's dance lessons or tutoring, I'm willing to spend on it. I want my kids to work for their success, but I'll be right at their side as they do.

I know the differences resources can make. My mom didn't have money but wanted me to attend a private high school. She asked my grandmother to pay for my schooling; in exchange, my mom didn't get anything in the will when my grandmother died since the tuition was her inheritance. I'm lucky not to have to make difficult choices like that, but I'm motivated to give everything I can to my kids.

More than anything, I want my children to grow up in a positive, encouraging environment. They'll need to work hard and be leaders, but I want them to know life isn't just about making money; it's about being a good person.
