Flying into BWI: common questions

Which runway will my flight use at BWI?

It depends mostly on the wind: airplanes take off and land into the wind where they can, so the runway in use changes with the weather. FAA data lists 3 runways at BWI (10/28, 15L/33R, 15R/33L); the longest is 10/28 at about 10,503 ft.

Why might my flight circle before landing at BWI?

Holding is a normal way for air traffic control to space out arrivals when it's busy or the weather changes. Airplanes carry extra fuel for it. You can check current delay programs on the FAA's National Airspace System status page.

Is it normal for the landing at BWI to feel bumpy?

Yes. Low-level bumps are common on approach, especially on windy or gusty days, and a firm touchdown is often deliberate. The airplane is designed for it; keep your seat belt fastened while seated.

What can I bring through security at BWI?

TSA rules apply at every US airport: liquids in your carry-on must be in containers of 3.4 ounces (100 ml) or less, all in one quart-sized bag. TSA's 'What can I bring?' tool covers specific items.
