Should You Fly From a Different Nearby Airport Instead?

Often, yes. Washington Dulles (IAD) departs on time 83.2% of the time — 9.9 points better than nearby Baltimore/Washington International (BWI) at 73.3%, even though the two airports are only 45 miles apart and serve the same metro area. Similar gaps show up around San Francisco and Los Angeles, where a smaller nearby airport consistently outperforms the region's biggest hub.

Key takeaways

• Washington, DC area: Dulles (IAD) 83.2% on-time vs. BWI 73.3% — a 9.9-point gap within 45 miles
• San Francisco Bay Area: San Jose (SJC) 83.6% on-time vs. SFO 79.6% vs. Oakland (OAK) 79.8%
• Los Angeles area: Long Beach (LGB) 84.1% on-time vs. LAX 81.9% vs. John Wayne/Orange County (SNA) 81.7%
• In every metro area checked, the smaller regional airport had a higher on-time rate than the largest hub

Washington, DC: Dulles vs. Reagan National vs. BWI

• Dulles (IAD) — 83.2% on-time departures, 14.9-minute average delay, 45 miles from BWI
• Reagan National (DCA) — 75.9% on-time departures, 19.7-minute average delay, 23 miles from Dulles
• Baltimore/Washington (BWI) — 73.3% on-time departures, 17.0-minute average delay, 30 miles from Reagan National

For a traveler willing to drive 30–45 minutes further, Dulles beats BWI by nearly 10 points and Reagan National by more than 7.

San Francisco Bay Area: San Jose vs. SFO vs. Oakland

• San Jose (SJC) — 83.6% on-time departures, 10.3-minute average delay, 30 miles from SFO
• Oakland (OAK) — 79.8% on-time departures, 11.5-minute average delay, 11 miles from SFO
• San Francisco (SFO) — 79.6% on-time departures, 15.3-minute average delay

Both alternate Bay Area airports beat SFO, and San Jose's 30-mile drive comes with a nearly 4-point better on-time rate and almost 5 fewer minutes of average delay.

Los Angeles: Long Beach vs. LAX vs. John Wayne

• Long Beach (LGB) — 84.1% on-time departures, 9.5-minute average delay, 17 miles from LAX
• LAX — 81.9% on-time departures, 13.7-minute average delay
• John Wayne/Orange County (SNA) — 81.7% on-time departures, 14.4-minute average delay, 36 miles from LAX

Why do smaller nearby airports often perform better?

The pattern that shows up across all three metro areas is the same: the largest hub in each region has the lowest on-time rate of the group. Big hubs run far more simultaneous operations, funnel more connecting traffic through the same runways, and are more exposed to cascading delays from congestion elsewhere in the network. A smaller regional airport with fewer daily departures and simpler point-to-point schedules has less opportunity for that congestion to build up.

How to check if switching airports is worth it for your trip

The right call depends on your specific trip, not just the metro-wide averages above — a route only a nearby airport serves, or a much longer drive, can outweigh the on-time gain. Look up both airports on FlightRecord, compare their on-time rates and average delays, and weigh that against the extra travel time to reach the alternate airport.

Frequently asked questions

Is it worth driving further to a more reliable airport?

It can be. In the Washington, DC area, driving the extra distance to Dulles instead of BWI corresponds to a nearly 10-point better on-time rate. Whether that trade-off is worth it depends on how much extra drive time is involved and whether your specific route is served from both airports.

Are smaller airports always more reliable than big hubs?

Not always, but in the three major metro areas checked here — Washington, DC, the San Francisco Bay Area, and Los Angeles — the smaller regional airport outperformed the largest hub every time. Always check the specific airports involved rather than assuming.

How do I compare two nearby airports' reliability?

Search each airport by name or code on FlightRecord to see its on-time departure rate, average delay, and cancellation rate side by side, all computed from the same 24 months of US DOT data.

All figures are computed from US DOT Bureau of Transportation Statistics on-time data — see our methodology. Compare airports directly: IAD, DCA, BWI, SJC, SFO, OAK, LGB, LAX, or SNA, or see the full most reliable airports ranking.
