In 1938, the Empire Terminal of Imperial Airways opened opposite the coach station, designed by Albert Lakeman, also in the Art Deco style.

It allowed passengers to check-in before boarding special trains from Victoria Station to Croydon Airport or Southampton Docks for the flying boat service.

The terminal continued in service until the end of the 1970s, by which time there were dedicated rail or bus connections to Gatwick and Heathrow Airports.

Following a national fundraising campaign called "Save Our Stuff", the Guides were able to move into their own purpose-built headquarters at 17–19 Buckingham Palace Road, which they still occupy today.
