JetBlue and Endeavor Air face the highest number of flight cancellations worldwide following two consecutive days of FAA ground stops and severe weather disruptions across major US airports.

Severe weather in the Northeast has triggered a cascade of FAA ground stops, leaving JetBlue and Endeavor Air with the highest cancellation rates globally as of July 28, 2026.
The Federal Aviation Administration (FAA) implemented traffic management measures for two consecutive days, causing systemic failures across several of the busiest aviation hubs in the United States. The disruption is centered primarily on the East Coast, where flash flooding and thunderstorms have crippled operations.
Escalating Operational Failures
JetBlue experienced a dramatic surge in disruptions between July 27 and the morning of July 28. While the carrier struggled with 377 delays and 52 cancellations on Monday, the situation deteriorated rapidly by 6:00 AM EST Tuesday.
Endeavor Air, which operates regional services for Delta Connection, has similarly seen its network collapse under the pressure of weather-induced ground stops. The airline reported a 30% network cancellation rate, with the majority of the impact felt at LaGuardia Airport.
Critical Flight Data: July 27 vs. July 28
The following data illustrates the sharp increase in instability for JetBlue's operations:
| JetBlue Operations | July 27 | July 28 (6:00 AM EST) |
|---|---|---|
| Flights Delayed | 377 (34%) | 29 (2%) |
| Flights Canceled | 52 (4%) | 223 (21%) |
Affected Hubs and FAA Restrictions
The FAA Air Traffic Control Command Center issued ground stops and delays across a wide array of airports. These measures prevent aircraft from departing for affected cities until conditions improve or congestion is managed.
July 27 Affected Airports:
- New York LaGuardia (LGA)
- Atlanta (ATL)
- Newark (EWR)
- New York (JFK)
- Teterboro (TEB)
- San Francisco (SFO)
- Chicago O'Hare (ORD)
- Chicago Midway (MDW)
- Washington Dulles (IAD)
- Orlando (MCO)
- Tampa (TPA)
- Philadelphia (PHL)
July 28 Continued Restrictions:
- Atlanta (ATL)
- New York (JFK)
- Newark (EWR)
- Chicago O'Hare (ORD)
- San Francisco (SFO)
- San Diego (SAN)
- Philadelphia (PHL)
Comparative Airline Impact
While JetBlue and Endeavor Air lead the cancellation rankings, the disruption has affected nearly every major US carrier.
| Airline | Canceled Flights (July 27) | Delayed Flights (July 27) | Canceled Flights (July 28) | Delayed Flights (July 28) |
|---|---|---|---|---|
| SkyWest | 298 | 648 | 55 | 113 |
| Republic Airways | 268 | 273 | 210 | 47 |
| United Airlines | 234 | 1,162 | 73 | 94 |
| American Airlines | 173 | 1,218 | 39 | 116 |
| Envoy Air | 140 | 187 | 7 | 0 |
| Southwest | 124 | 1,367 | 45 | 231 |
| GoJet | 111 | 29 | 40 | 9 |
| Endeavor Air | 105 | 300 | 252 | 46 |
| Delta Air Lines | 66 | 1,191 | 98 | 88 |
| JetBlue | 52 | 377 | 223 | 41 |
Why This Matters: Industry Analysis
From a logistical perspective, this event highlights the extreme fragility of the US "hub-and-spoke" model. When a primary node like LaGuardia or JFK is throttled by the FAA, the knock-on effects are not localized; they ripple across the entire national network.
For travelers, the real impact is the "recovery lag." While a storm may pass in six hours, the displacement of aircraft and crews takes days to resolve. JetBlue’s heavy concentration in New York and Boston makes it disproportionately vulnerable to Northeast weather patterns. The fact that Endeavor Air (Delta Connection) is seeing a 30% network cancellation rate suggests that regional feed into major hubs is currently the weakest link in the aviation chain.
Forward Outlook
The National Weather Service indicates that severe thunderstorms and flash flooding will persist in the Northeast for several more days. Passengers should expect continued volatility. JetBlue has waived change and cancellation fees for flights to and from Long Island/Islip (ISP), New York (JFK, LGA), Newark (EWR), and Westchester County (HPN) through July 29, 2026.
Industry trends suggest that until airlines diversify their hub dependencies or the FAA implements more flexible dynamic routing, these "cluster cancellations" will remain a recurring risk during peak summer storm seasons.
