DALLAS — Newark Liberty International Airport (EWR) is experiencing an unprecedented operational crisis, with flight cancellations soaring to alarming levels since April 26, 2025. 

Today's data from aviation analytics company Cirium shows the situation has deteriorated further, with 68 flights canceled and significant delays affecting thousands of travelers. This report analyzes the factors behind this disruption and its financial impact on airlines and passengers.

Sharp Increase in Cancellations

Cirium data reveals a troubling pattern at EWR. Before April 26, cancellations were managed at a reasonable level, with an average of just four flights canceled daily throughout early to mid-April. However, since April 26, the situation has deteriorated dramatically, with average daily cancellations surging nearly tenfold to 39 flights per day.

Today, Monday May 5., represents the peak of the crisis thus far, with 68 flights canceled – the highest single-day total since the disruption began. The chart below illustrates this dramatic spike in cancellation rates, with the problem worsening significantly in early May.

On-Time Performance Collapse

The operational challenges extend beyond cancellations. Newark's on-time departure performance, which had been maintaining a respectable 80% rate before April 26 (considered good by industry standards), has plummeted to just 63% in the period since.

This significant deviation places EWR among the worst-performing major airports in the country for on-time departures.

Root Causes Identified

As per the Cirium analysis, combined with industry and local reports, points to several interconnected factors behind this operational crisis:

1. Critical Air Traffic Control Staffing Shortage: According to industry executives, Newark's air traffic control facility has been "chronically understaffed for years," but the situation has reached a breaking point. The Philadelphia Terminal Radar Approach Control, which coordinates planes arriving at Newark, is severely understaffed, limiting the airport's capacity to handle its scheduled traffic volume.
2. Runway Construction: One of Newark's main runways is closed for rehabilitation work until mid-June 2025, reducing the airport's operational capacity. While necessary, this planned construction has exacerbated the effects of other issues.
3. Technology Failures: Multiple equipment outages have been reported, including a serious incident on April 28 when controllers lost radar and communications with aircraft under their control for 90 seconds. This has raised concerns about outdated infrastructure and technology at FAA facilities. As a result, air traffic controllers took 45-day ‘trauma leave’ after failures, according to the FAA
4. Weather Challenges: Low ceiling conditions have occasionally worsened the situation, with the most recent data showing arrival delays averaging nearly 4 hours due to poor visibility.

Financial Impact

With each minute of delay costing airlines approximately US$100, the financial impact of this crisis is substantial:

• The dramatic increase in delays since April 26 is costing airlines millions of dollars
• United Airlines (UA), EWR's dominant carrier, has been forced to cancel 35 round-trip flights daily (approximately 10% of its EWR schedule)
• Passenger compensation, crew overtime, and aircraft repositioning are creating additional costs

Passenger Experience

The impact on travelers has been severe. Many passengers have experienced:

• Flights diverted to alternative airports
• Extended waits on tarmacs at diversion airports
• Multi-hour delays both for departures and arrivals
• Last-minute cancellations
• Missed connections and disrupted travel plans

Industry Response

The situation has prompted significant responses from both airlines and regulators:

1. Schedule Reductions: United Airlines has unilaterally cut 10% of its Newark schedule (35 daily round-trip flights) to stabilize operations.
2. Calls for Capacity Controls: Airlines are urging the FAA to implement stricter capacity controls at Newark, similar to those at LaGuardia (LGA) and Reagan National (CDA) airports.
3. FAA Incentive Program: The Department of Transportation has announced new financial incentives to address the controller shortage, including recruiting military controllers and providing bonuses for academy graduates.

Outlook, Recommendations

Without immediate intervention, this operational crisis will likely continue through at least mid-June when runway construction is scheduled to be completed. Airlines and passengers should prepare for:

• Continued high cancellation rates
• Below-average on-time performance
• Potential further schedule reductions
• Minimal recovery capability during weather events

For travelers with upcoming flights through Newark:

• Consider alternative airports in the New York area when possible
• Allow additional connection time (3+ hours) for international itineraries
• Monitor flight status closely before departure
• Be prepared with contingency plans for delays and cancellations
• Check with airlines regarding fee waivers for changes and cancellations

The current situation at EWR represents one of the most significant operational disruptions at a major U.S. airport in recent years. Tomorrow's scheduled update on airline schedule changes will provide further insight into carriers' strategies for mitigating these challenges in the coming weeks.
