Why BWI Experiences Flight Delays: Unpacking Common Flight Delay Reasons
Several factors contribute to BWI airport flight delays, helping you set realistic travel expectations:
- Mid-Atlantic Weather: Winter snow, ice storms, coastal fog, and summer thunderstorms often cause ground stops, de-icing, or holding patterns.
- Shared Airspace & ATC Congestion: BWI shares busy D.C. airspace with DCA and IAD, where regional weather or traffic issues can cascade delays.
- Southwest’s High Volume: As BWI’s dominant carrier, Southwest’s frequent flights mean late arrivals can ripple across their schedule.
- Infrastructure Limits: BWI’s single terminal concentrates operations, where taxiway or gate issues during peak times cause bottlenecks.
- Northeast Corridor Effects: Delays at hubs like JFK, EWR, or PHL, or en-route issues, impact BWI even if local conditions are clear.
Our flight delay predictor tool analyzes these factors in real-time for tailored risk assessments.
