I don't know if it was directed at me, but I wasn't suggesting that say a "North of England" to S.America (or anywhere else) route should launch from say Newcastle or Liverpool. Clearly Manchester has the greatest appeal in the North plus the best network for passengers to access it by (road, rail & air). I don't know where posters are based, but on the Manchester threads I suspect in relative proximity to Manchester Airport. If that is the case, Manchester's long haul network is very convenient. Just think about it from the other perspective however. Lets say the Northern cities had developed differently and the major northern airport was in Newcastle. I'd be very surprised if you didn't get the slightest bit frustrated if those local to Newcastle continuously pushed for ever more routes from Newcastle and for the population of 'the North' to use Newcastle for as much of their flying as they could.
Using your "why should they expend time and resources on launching the new route from BHX" regading Orlando, why dd VS start at MAN? Or with such an "obvious" market in BHX-MCO, why didn't TCX approach BHX saying let's work together to provide this link 3 or 4 times a week and we may also be able to squeeze in another service say 2 or 3 times a week to JFK. After all, there's much greater competition at MAN so why not enjoy being the "big shot" at BHX? Why did CX restart MAN? Or any of the other airlines doing long-haul? Or come to that, any airline doing any short-haul route. All are available at LHR and LGW. These stupid airlines, recklessly adding routes at MAN when they have determined they are commercially viable. Oh, there's that phrase "commercially viable".
Let me expand on my point here: why would say Thomas Cook launch BHX-Orlando, when 'Midlanders' currently are "prepared" to travel to Manchester (& Gatwick) for flights to Orlando? Whilst yes it would mean they would have a near monopoly on BHX-Orlando, it would mean people leaving the current services from Manchester/Gatwick to use the new one from BHX. What affect would that have on their yields from those currently served airports? By serving Manchester & Gatwick, an airline can cover most of the country south of the Pennines. That doesn't mean that by serving those 2 airports that there isn't enough demand to fly from other airports in between.
Orlando is of particular frustration to us local to BHX, as I think the following stats show.
During the summer, Manchester has more flights in 1 week than Birmingham does in an entire year.
2016 Passenger Figures
Manchester 543,021
Glasgow 115,335
Stansted 51,184
Newcastle 17,435
Birmingham 17,190
Manchester (January 2017) - 16,319
Birmingham (Jan-Dec 2016) - 17,190
I accept Birmingham won't have as many passengers flying to Orlando as Manchester, but personally I would have thought there's enough demand to handle at least as many passengers to Orlando as Glasgow does if not more. To put the numbers into perspective, it would mean 744 passengers flying Manchester to Orlando every day, whilst Glasgow would be 158, and Birmingham just 24. I appreciate Manchester gets some passengers transferring onto those Orlando flights from other flights, but we 'Brummies' cannot fathom why no airline is looking seriously at Birmingham to Orlando. You can't be suggesting that Birmingham to Orlando isn't a "commercially viable" route?
Let me reiterate. I'm not suggesting new long haul routes should be diverted away from Manchester to other airports. MAN is the natural hub for the North on England and if any airport outside of London were to get a new route to say Tokyo, Rio, Seoul, etc I would be incredibly surprised if it wasn't Manchester. Those that are loyal to Manchester must be aware however that there are other airports out there which 'should' be able to support long haul flights, and that it is not a given right that passengers in the North (or Midlands) should use Manchester for their long haul flying.
