Most cabin crew I spoke to feel that IFS Moon should be given a fairer punishment by demoting him to the position of chief steward (1 rank down) rather than the position of leading steward (2 rank down) which most think it's too severe. IFS Moon is appealing to the management to be a bit more lenient by giving him another chance.
Frankly, it's no big deal about upgrading our own cabin crew when they are flying as passengers. Most airlines do it. The cc are well behaved people when flying as passengers.
I recall a time when a station manager from Australia upgraded SQ staff to the first class when the flight to SIN was overbooked in the EY and JC. These staff were on "standby" and they did not have a right to the business class let alone flying in the first class. If "off-loaded" the staff would have to pay for their own accommodation and catch another flight home the next day. But the station manager took pity on the staff and upgraded them. I was working on that flight and I, on behalf of the staff expressed gratitude to this station manager.
The " gud old days" was the period whereby the company did not even bat an eyelid when we upgrade someone. The company do not suffer any monetary loss but those were the days of understanding and compassion by a then great company.
