As my 'lifetime' is somewhat inhibited by my age, I have no personal interest in the prospect!
That said, if LTS would cost BA more than, say, £180.47 per annum, globally, I doubt I will see it being introduced in MY lifetime. Younger subscribers here will clearly have a different view.
BA is no longer the benevolent old Uncle we used to know. Instead, he has morphed into a penny-pinching old Grandfather (the image of Private Fraser from Dad's Army flashes across my mind) who cares naught for anyone or anything except scraping money from every corner of his existence, and shovelling it into a tin under the bed.
