Can you get a look at old magazines? Can't expect to get every year for every airline, but some stats did appear in the 1960 era. American Aviation (which became Airlift around then) published passengers and passenger-miles for US airlines, and sometimes for some foreign, including BOAC if not BEA.
Samples:
The table in the 28 Apr 1952 issue says BEA carried 912,604 revenue passengers in 1950, 1,121,439 in 1951. Available seat-miles 429,823,148 in 1950, 493,968,220 in 1951; revenue passenger miles, 259,046,195 in 1950, 329,452,420 in 1951.
Airlift May 1962 gives revenue passengers and revenue passenger-miles (thousands) in 1961
Autair 10000 - 400
BEA 4,355,442 - 1,538,888
BOAC 852,941 - 2,654,272
British United 424,157 - 705,500
Channel Air Bridge 238,000 - 28,011
Cunard Eagle 151,135 - 37,486
Same issue says BEA Vanguards carried 198,568 thousand RPMs in 1961, Viscount 800s (?) carried 694,990, Viscount 700s (?) carried 244,188, and Comets carried 335,614.
The June issue says BKS carried 194682 passengers in 1961, 48251 thousand RPMs.
Then in the July issue, a correction: British United RPMs were actually 82542 thousand.
