BWI is the short code for a big airport in the United States that serves both Baltimore, Maryland, and Washington, D.C. It sits between those two cities, so a ticket that says BWI is not sending you into the middle of Washington itself — though actually that is the point: one airport, two cities. , airlines, and boards say the three letters one by one: B-W-I. You meet it on tickets, maps, and luggage tags. If a flight into Washington looks expensive, people often fly into BWI instead. It is airport English, not a word you use at home.
BWI（巴爾的摩／華盛頓國際機場）
組成The first letters of Baltimore/Washington International, the airport’s name. People say each letter.
