Frankfurt Airport canceled over 100 flights Thursday after climate activists creatively breached security fences with bicycles and skateboards, reminding everyone that climate change can really throw a wrench in your travel plans.

With the audacity of an eco-friendly skate park gang, overzealous climate crusaders from 'The Last Generation' literally rolled past Frankfurt Airport's security, causing the largest flight disruption seen this week. As part of a broader European movement to underscore the urgency of tackling fossil fuel emissions, these activists ensured that not just passengers, but the entire aviation industry, felt the turbulence of environmental protest. Amid tightened security and looming harsher penalties, airports across Europe brace for a chaotic summer reminiscent of a rebellious summer camp.

Frankfurt Airport had to put on the brakes completely for a period in the early hours, creating a scene that could have only been inspired by a chaotic flash mob. All runways were back in operation by 7:50 a.m. local time, but not before more than 140 flights were canceled, with expectations of additional disruptions.

The Last Generation group, evidently not content with merely clicking 'like' on eco-conscious articles, organized the demonstration at Frankfurt with six protesters making surgical cuts in the perimeter fence before heading toward the runways. Their arsenal included not just their highly expressive banners, but also an unlikely fleet of bicycles and skateboards.

Frankfurt wasn't the only airport feeling the green wave. On Wednesday, similarly outspoken members of The Last Generation managed to halt flights at Cologne-Bonn Airport for approximately three hours, resulting in 31 flight cancellations. It appears the group is highly adept at turning airports into their personal stages for climate performances.

Meanwhile, attempts to extend this eco-friendly disruption to London's Heathrow Airport were nipped in the bud by police, who arrested seven Just Stop Oil members before they could enact their flight-stopping plans. The planned protest was clearly no match for British law enforcement's crackdown.

This week's surge in airport targeting has been part of a Europe-wide wave to raise the profile of climate change. Airports in Finland, Norway, Switzerland, and Spain also saw coordinated protests. At Helsinki Airport, protesters created a brief bottleneck in the main check-in area for about 30 minutes without managing to cause any delayed flights. It seems even climate protesters prefer timely departures.

Oslo's Gardermoen airport saw a trio of activists waving banners and disrupting air traffic early Wednesday morning. Fortunately for travelers, their performance only lasted about half an hour with no significant delays recorded.

Such frequency and coordination have lent notable credibility and raised the stakes substantially. The German government doesn't seem too amused; the Cabinet has green-lighted legislation imposing harsher penalties for such daring airside intrusions, with potential prison sentences of up to two years. However, the new rules still require lawmakers’ approval. One wonders if the latest antics will fast-track this legislative process.

As temperature records are being broken and global investments in oil and gas are paradoxically increasing, the climate activism seen at Frankfurt Airport serves as a frenetic, if somewhat disorganized, attempt to remind the world of the stark linkage between fossil fuels and climate change. Monday, for instance, was crowned the hottest day ever recorded—a rather dubious honor attributed to human-induced climate change.

Environmental groups are calling on governments to pull the plug on fossil fuel extraction and combustion by 2030, and it seems the Frankfurt activists decided that there’s no time like the present to emphasize this urgency—preferably from the middle of a runway.

With the summer just kicking off, many are starting to wonder whether packing an extra book for probable airport delays might be the new travel norm. It appears we should all brace ourselves for a summer where the flight status board might flip between 'Departed,' 'Delayed,' and 'Disrupted by Environmental Activists' with regularity.
