Kernrechtsfrage
Whether the employer had standing to be sued for the unpaid pre-retirement benefits
Extrahierter Entscheid
The employer remained bound; the letter of 31 August 1998 created obligations for Swissport toward the employee.
Extrahierte Begründung
The wording of the letter, its letterhead, and the context allowed the employee to understand in good faith that Swissport undertook the obligations; group-internal funding arrangements did not matter.
