it seems the time has come for the faaa lh to set an example (the shire fishing club might not agree on that one) and proacticely canvasse alternate options for lh cabincrew before a legal challenge will put them in a corner. it might not be a perfect sytem/ addition but it would certainly improve the current limited options.
my advise would be
1) instant trip swap system online. with set rules which cannot be interfered, like MPT, no interference from operations,etc. this would also give cabin crew flexibility to add extra hours as long as it does not interfere with the above rules. lets face it there are still a number of cabin crew out there who do well in excess of 200 hrs.
and they do it by infringing their mpt (yes you too, faaa official)
2) limit the number of trips you can make in one bid period. leets say only 3 lax per bid period. yes , sorry old chaps
that would mean you have to explore another bar/burger joint somewhere else.
just kicking the ball along. certainly any changes need fine tuning, but you are better of controlling the ball then someone else.
germany just raise their retirement age for cabin crew to 65. BA is proposing to move it from 55 to 65 as well. the rest of europa will follow. in the US you have already the flying RSL.
