BEA also had a 'Social' Housing scheme for staff - My pal had a flat in Hounslow that was part of that scheme - No idea if it carried on in later years...Does it survive?
They also owned Aerad ? International Aeradio, Ltd. for charts etc.
BEA Silver Wing holidays, and Enterprise Holidays (Which BEA Airtours was the in-house airline from 1970) I think the Sales offices were in Central London?
I cannot recall when Martin Rooks Holidays was owned by BEA. Their office was in Ebury St SW.1
Queues around the block even, with Mum & Dad on Sundays when the new summer brochure and holidays were released just after Xmas each year.
