Leeds Bradford – 1960s flights

Does anyone know if there is a website which shows details of past flights. I am trying to identify the aircraft I flew in during the 1960s and 1970s.

I have dates, airlines and in some cases times, but would very much like to know the identity of the aircraft. For example I flew from LBA to Heathrow in the late afternoon in a BKS HS748 on 31 March 1964, returning on 16 April 1964, but have no serials.

A later example was a BA viscount flight from LHR to LBA (flight no BA5412), on 2 March 1979 (approx 17.40hrs landing 18.40hrs).

Any advice on where to look (if at all) much appreciated!
