Not only in BA.....
From the FT:
KLM recruits pilots for down-to-earth duties
... Two jobs the pilots are being asked to cover are “baggage recovery agents” in the arrivals hall and “hospitality agents” in the airline’s business class lounges...
KLM cabin crew was asked in March to either opt for a temporary lower employment percentage or take unpaid leave. Enough CC availed themselves of the various schemes, and the company will not have CC sitting at home on full pay this summer.
KLM also wants to avoid pilots sitting at home on full pay, so the above scheme was proposed in addition to unpaid leave and temporary lower employment percentages.
Apparently the number of pilots going for the above has risen since.
