United flight to Chicago diverted to Green Bay, stranding passengers for nine hours

Quick summary

United Airlines flight UA119, operating Edinburgh to Chicago O’Hare on July 27, 2026, diverted to Austin Straubel International Airport in Green Bay, Wisconsin, due to severe thunderstorms — including multiple tornadoes — over the Chicago area. What followed was a nine-hour ground ordeal: four hours onboard the aircraft, then roughly five more hours in a controlled outdoor customs holding area, as the original crew hit their FAA-mandated duty limit and US Customs and Border Protection could not process the international passengers at a facility with no 24/7 staffing for unscheduled arrivals.

The aircraft finally pushed back for Chicago at 10:19 PM, landing at O’Hare around 11:14 PM CDT — nine hours behind schedule. At least one passenger connecting to Denver arrived approximately 20 hours late.

The Boeing 757-200 carrying passengers from Edinburgh touched down at Green Bay just after 2:00 PM on July 27, with Chicago still locked under severe weather. Simple Flying reported that the crew had initially planned to push back for O’Hare by 3:05 PM — a reasonable assumption given the 175-mile gap between the two airports. That window closed fast.

After four hours parked on the ramp, the crew began taxiing for departure. Then the aircraft turned back. The original flight crew had reached their FAA Part 117 duty limit — the federal ceiling on how long a flight crew can legally operate — and could not continue. A replacement crew would have to be positioned from elsewhere, a process that takes time even when airlines move quickly.

With the crew change underway, United needed somewhere to put the passengers. The terminal was not an option. Austin Straubel’s US Customs office runs standard weekday hours, and the CBP fact sheet for the airport makes clear that inspection services outside those hours require advance permission-to-land arrangements — arrangements that were not in place for an unscheduled diversion. CBP permitted passengers to deplane, but only into a fenced, controlled tarmac area outside the customs facility. That is where they stayed for roughly five hours, with limited food provided.

The replacement crew eventually arrived. UA119 pushed back at 10:19 PM and covered the short hop to O’Hare in about 37 minutes, landing at approximately 10:55 PM — with flight tracking showing the aircraft at Chicago by 11:14 PM CDT.

How a weather diversion became a nine-hour ground hold

The National Weather Service recorded several tornadoes in the Chicago area that day, with wind gusts reaching around 100 mph across the region. Diverting was not a judgment call — it was the only option. Green Bay, roughly 175 miles north of O’Hare, was within range for a Boeing 757-200 running low on options.

The structural problem emerged on the ground. FAA duty clocks do not pause during diversions. Every hour the crew sat at Green Bay consumed what remained of their legal duty window, and by the time the aircraft began taxiing, that window had closed. Under 14 CFR §259.4, the federal tarmac-delay rule, airlines must offer international passengers a deplaning opportunity before a four-hour tarmac delay — but the rule includes safety and security exceptions, and CBP’s constraints at Green Bay effectively defined the security boundary.

The Austin Straubel customs page lists standard office hours as 8:00 AM to 4:30 PM Monday through Friday. The CBP fact sheet for the airport confirms that 24/7 inspection services exist — but only when carriers have pre-arranged permission-to-land rights. Without that prior coordination, an unscheduled international arrival lands in a grey zone: passengers can deplane, but not into the terminal.

United stated that CBP officers permitted passengers to move to a controlled tarmac area outside the customs facility. That is where they remained — outdoors, with pizza as the primary food provision — for approximately five hours. One passenger connecting onward to Denver ultimately arrived around 20 hours behind schedule. United initially offered that traveler $200 in flight credit, later raising it to $500.

Why small airports and transatlantic diversions are a bad combination

The mechanics here are worth understanding, because they apply to any transatlantic flight routing into a congested US hub during storm season. FAA Part 117 sets hard ceilings on flight duty periods — the clock starts when the crew reports for duty and does not stop for weather holds, ground delays, or diversions. A transatlantic crew arriving at a diversion airport after an eight-plus-hour flight may have very little duty time remaining. An hour or two on the ground can exhaust it entirely, even if the weather clears and the aircraft is ready to go.

CBP staffing at non-hub airports adds a second constraint that airlines cannot easily override. Austin Straubel handles mostly domestic and general aviation traffic — its customs infrastructure reflects that reality. The permission-to-land system exists precisely because the airport cannot staff for unscheduled international arrivals around the clock. When a widebody diverts without prior notice, CBP’s options narrow to: process passengers within the existing facility footprint, or hold them in a controlled area until the situation resolves.

The US Department of Transportation’s tarmac-delay rules set a floor — food and water within two hours, working lavatories, deplaning opportunity before four hours — but they do not guarantee terminal access or rapid onward travel. The four-hour deplaning threshold has a security exception, and CBP’s constraints at Green Bay fit squarely within it.

Protecting yourself on transatlantic flights that divert

Transatlantic diversions to non-hub US airports are rare but not exceptional — and when crew duty limits and customs constraints collide, a two-hour weather hold can become an overnight situation with very little warning.

• Ask the crew directly about CBP clearance. If your flight diverts to a smaller US airport, ask whether CBP can process international passengers into the terminal or whether you’ll be confined to a controlled area. The answer shapes everything — medication access, food options, rebooking logistics.
• Know the two-hour food and water rule. Under 14 CFR §259.4, airlines must provide food and potable water within two hours of a tarmac delay beginning. If that doesn’t happen, document the time and note it for any subsequent complaint.
• Document everything with timestamps. If you’re held beyond four hours, note exactly when deplaning was offered (or not), what food was provided, and whether lavatories remained operational. This record supports DOT complaints and any goodwill compensation request.
• File with DOT, not just the airline. After any tarmac delay exceeding four hours on an international flight, submit a formal complaint to the DOT’s Aviation Consumer Protection office at transportation.gov alongside any airline claim. DOT tracks complaint patterns and uses them in enforcement reviews.
• Build buffer into transatlantic connections. A same-day domestic connection after a transatlantic arrival into a storm-prone hub like O’Hare in summer is a risk. A minimum three-hour connection — ideally more — gives you a fighting chance if the inbound flight diverts.

Watch: Whether United updates its diversion airport list for transatlantic routes to exclude non-hub airports without pre-arranged CBP permission-to-land agreements — any policy change would likely surface in DOT filings or United’s customer service guidelines within the next few months.
