Understanding Low-Visibility Flight Delays and How to Mitigate Them

Low-visibility conditions, such as fog, heavy rain, or snow, can significantly impact flight operations, leading to delays and cancellations. Understanding these conditions and how to mitigate their effects can enhance your travel experience.

What Are Low-Visibility Flight Delays?

Low-visibility flight delays occur when weather conditions reduce a pilot's ability to see the runway or other aircraft, compromising safety. Common causes include fog, heavy rain, snow, and low cloud ceilings. These conditions can lead to slower aircraft movements, longer taxi times, and, in severe cases, grounded flights.

How Do Low-Visibility Conditions Affect Airports?

Airports implement various measures to manage low-visibility situations:

• Instrument Landing Systems (ILS): ILS guides aircraft during landing in low-visibility conditions.

• Surface Movement Guidance and Control Systems (SMGCS): SMGCS provides guidance for aircraft and vehicle movements on the ground during low-visibility operations. (faa.gov)

• Ground Delay Programs (GDPs): Air traffic control may implement GDPs to manage air traffic flow during adverse weather, leading to departure delays. (nbcbayarea.com)

Recent Examples of Low-Visibility Delays

• San Francisco International Airport (SFO): In May 2026, low cloud ceilings led to a ground delay program, causing significant delays for flights departing and arriving between 8 a.m. and 11 p.m. (nbcbayarea.com)

• New York Region: In February 2026, low ceilings and visibility were primary factors affecting terminal operations at airports like New York's JFK and LaGuardia. (adept.travel)

How to Mitigate the Impact of Low-Visibility Delays

1. Stay Informed: Regularly check the Federal Aviation Administration's (FAA) Flight Information for real-time updates on airport statuses and delays.

2. Plan Ahead: Consider booking flights during times when low-visibility conditions are less likely, such as midday or early afternoon.

3. Choose Alternative Airports: If your destination airport is prone to low-visibility delays, explore nearby airports with better on-time performance.

4. Allow Extra Time: Allocate additional time for connections and potential delays, especially during seasons known for low-visibility weather.
