What allowances should be included in a pilot’s holiday pay?

The ECJ has ruled that a pilot’s holiday pay should include an allowance (e.g. a flying time allowance) that is intrinsically linked to the performance of the pilot’s job duties [see para. 24].

However, the law did not require the pilot’s holiday pay to include an allowance (e.g. a time away from base allowance) that is intended to cover ancillary expenses arising from the performance of the pilot’s job duties [see para 25].
