I would be surprised! Surely the point of attaining LTG is that at some point in the future you can relax and stop flying on a regular basis? Whether change of job, location or simply retirement... you shouldn’t have to keep flying BA four times a year to keep your LTG status.

it comes back to the scenario that if, as a LTG,you are only flying now and again you are not really costing BA much anyway.

it is a reward for your past loyalty.
