British Airways is offering a £20 discount, per person, when you spend at least £100 on an Economy Euro-Traveller flight. The promotion is in conjunction with Lloyds TSB, and is meant for Lloyds TSB credit card holders, but it is unlikely that BA will be able to cross reference those that use it with Lloyds TSB’s customer database.
To get the discount, enter promo code LTSBMARZH on the britishairways.com booking page by following the “Got a promotion code?” link. You must book by 12th April 2013 and travel between 1st April 2013 and 30th June 2013. Booking classes Y,B,H,K,M,L,S,V,N,Q and O are included in the offer, but Domestic and BA City Flyer flights are excluded, as are one-way bookings.
