Key Routes from IAH

Delay Patterns at IAH

Houston's Gulf Coast location means weather is the dominant factor in IAH delays. Understanding seasonal patterns helps set expectations:

Summer (May–Sep)

Intense afternoon thunderstorms are nearly daily occurrences in Houston. Convective cells build quickly, producing heavy rain, lightning, and occasional hail. Ground stops and ground delay programs are common between 2–8 PM. The extended summer storm season (May through September) is IAH's most challenging period.

Hurricane Season (Jun–Nov)

Tropical storms and hurricanes in the Gulf of Mexico can shut down IAH operations for days. Even distant tropical systems can produce sustained rain bands and wind that reduce capacity. Hurricane preparations may trigger preemptive cancellations 24–48 hours before landfall.

Winter (Dec–Feb)

Rare ice storms and freezing rain events can paralyze operations, as IAH has limited de-icing infrastructure compared to northern hubs. Fog is also common in winter mornings along the Gulf Coast.

Tip: Morning departures (before 11 AM) have the best on-time performance at IAH. Summer thunderstorms build in the afternoon, so early flights consistently outperform evening departures.

Delta Air Lines is actively equipping its fleet with Starlink satellite internet — the fastest WiFi ever offered on a commercial airline. IAH-based narrowbody and widebody aircraft, including 737 MAX 8, 737 MAX 9, and A321neo, are among the first aircraft types receiving Starlink installations.

Use Widget Watch's Fleet tab to check if your specific aircraft has Starlink. You can search by tail number, flight number, or aircraft type.

How to check: Look up your flight on Widget Watch → check the aircraft details panel → look for "Starlink" in the WiFi field. Equipped aircraft show ● Starlink.
