BD offers a card in the UK which earns 20K bonus miles for sign up and then up to 2 miles per GBP sent on the card which can add up quickly. Keep that in mind when deciding on which programme to go with.

BD *G only lasts one year and must be requalified within your membership year to maintain it. LH*G on the other hand lasts two, but you have to get all qualifying miles to maintain in one of those two years.
