Well that's what the TfGM growth strategy says. All this is in the context of the £243m extra Treasury funding (to be spent by 2022) for Greater Manchester local transport networks in support of NPR and HS2. It appears that the Altrincham-Airport busway is currently a front runner for this budget (though I am sure TfGM will try to get the Airport and Royal London to stump up a fair proportion of the cost).
Just generalising the thread, but are you saying the £243 million extra (mentioned in the Autumn Statement) is specifically and solely to support HS2 and NPR related schemes?
Of course, there will also be a cycleway alongside; maybe that will endear it more to Altrincham types? In any case, both the LSM busway and the Cambridgeshire busway find that reluctant car users (of whom there are vast numbers) are their biggest source of business, so if Altrincham and Poynton are full of potential travellers who have not been on a bus since school, that could well prove an ideal market. It is the former regular stopping bus users who are most likely to be dissatisfied with busway services - the whole principle of 'walking further to travel faster' only works for those who are arsed to travel faster in the first place.
Maybe I'm overestimating the "snob factor" here, although in the "populist" 20th century its probably more reverse snobbery. I recall an occasion a few years ago when two drunken yobs got on a Hope Valley line instead of an Ashton train by mistake, and when told they needed to get off at Reddish North, they asked how to get to Ashton. They were advised to catch a 7 bus (this was before it was re-routed away from North Reddish), but retorted "We don't do buses, when's the next f**king train back to Manchester?"
Stockport is unlikely to get an all-dancing BRT link - more likely just improved bus priority along Bramhall Lane towards the Airport. But long-term TfGM envisage Audenshaw/Denton to the Airport via Stockport interchange as an orbital tram-train route - coming off the heavy rail line onto the tram tracks at Baguley, and then running via Wythenshawe hospital and the HS2 station into the Airport station from the west.
Again, maybe as a child and young adult of the (regulated) 70s/80s, my economic attitudes and lessons no longer hold sway in the 21st Century, but I can never get my head around this idea of BRT being favoured for higher car owning catchment areas, often with longer distances to cover, and Rail being favoured for lower car ownership areas, often only a short distance from the regional centre (or in this example) another major town. I was trying to visualise (based on probably two trips either way to Leigh and not yet using a V2), how far apart the stops were on LGB. Whilst obviously further than the 250-300 metres average, they seemed to be within reasonable distance of each other for the vast majority of ambulent people to use. I don't think this is the case for Metrolink (maybe a mile apart, once outside the city?) nor obviously heavy rail. Thus most would want/need private transport to reach Rail, which obviously must mean increased car ownership - and with the state of our Transport Economics, that's got to translate as an exponential increase in car use.
I was talking specifically about bus ridership into Manchester city centre; which has indeed been 'flat' since 2011 . Which is surprising, as over the same period more and more former car drivers have been desperate to switch to any sort of reasonable alternative mode of transport for getting to work. Given that jobs in the city centre have been increasing so fast, it takes a special degree of gross incompetence that bus services into Manchester city centre are not achieving rapidly expanding ridership figures in line with those for rail and tram services. Incompetence more on behalf of the policymakers than the operators perhaps.
