Pinkman I know we are leaving the EU and imposing tough controls on immigration to limit those terrible foreigners from entering our country, but I don't think we can afford for BA to limit itself to only carrying unfailingly polite Brits!!
I would also question how many decades ago it was when you last travelled on a holiday route with BA or any other British airline, because unfailingly polite is something very few Brits are these days.
10 abreast ............ perhaps it will be called the Samantha Fox cabin?
