Cabin crew have resisted changes for many years......
A few years ago the cabin crew at Gatwick were moved to the terms & conditions that BA want at LHR.
The LHR cabin crew declined to assist their colleagues at Gatwick resist that change.
Now BA want the same at LHR........
Given the state of the industry and BA in particular the BA offer isn't bad .. broadly they'd end up on thje same sorts of allowances etc as their LGW "comrades" but with no reduction in salary .. new lower salaries would only apply to new starters.
There's a bit more in the detail but that's broadly that.
However, the real deal is it's not particulalry about the money - it's about who runs BA.
The cabin crew believe they do ..... the CX thinks he'd like to have a go at running it instead
There's been a fair of "dirty tricks" ("allegedly") ... disgruntled cabin crew have been trying to start up a new crew body to represent them ..... it "appears" that the unions IT/Web person hacked their site and linked it to prono sites etc.
The two main unions involved Unite & BASSA refused to even sit together in the same room until quite recently so BA had to try and negotiate with each individually.
Sadly my experience (not just with BA) is that when an a/c doesn't go anywhere because of "crew hours" .. it's very often the cabin crew who stamped their feet and refused to use discrentionery hours - the pilots are often the first to to do what they can to get the thing moving - unless to do so would be illegal.
It's a sad fact that in aviation today the world is in turmoil - did you know that SAS almost went out of business last weekend
British Midland's survival depends on what it's current owner (Lufthansa) thinks it can salvage .. might be a lot .. might be nothing.
BA is currently known in the industry as "London Airways" - truth is it's long been regarded as this really - first thing it does when the going gets tough is cancel anything that doesn't start in Heathrow.
It flogged it's domestic flights to FlyBe who seem to be able to make money from it - BA reckoned it was a basket case...... then again that may have been due to BA's terms & conditions:-0)
I've rambled enough ... I'll stop now .. maybe p0pc0rn41
