Quite right NTarrant.
Staff travel is NOT a contractual benefit in kind and these discretionary perks form no part WHATSOEVER of the contract of employment.
You can see what these discretionary benefits entail here:
If you illustrate the “benefit” on a domestic flight, the saving is paltry as the fare component is often as low as £10, with the remaining £70 made up of taxes and fees. So a £9 saving would result.
But on a £600 economy fare to Sydney, for the BA employee and friends/family plus potential to upgrade depending on seniority, the perk could add up to thousands.
