Whilst I agree with more choice, wouldn't having BoB at LGW only only appear a bit illogical to the customer?
Also, if BA kept the free drink and biscuit, the offering would actually be superior to LHR since at least customers would have a choice in eating more.
Does this also mean the demise of CE at LGW, since customers may be able to buy a nicer meal, one of the CE USP's?
In light of Lufthansa's catering improvements, this would mean BA is no longer a full-service airline like them.
